Plastic Moulders UK Article | Demystifying Part Warp: Analysing Pressure Gradients, Polymer Temperature, and Their Effects on Residual Shear Stress and Shear Rate

 

The following article is from Ledwell Plastics, Plastic Moulders UK

When it comes to the manufacturing of plastic parts, one of the most common challenges faced is part warp. The phenomenon of part warp can be frustrating and costly, often resulting in rejections, rework, and even production delays. However, by understanding the underlying factors that contribute to part warp, such as pressure gradients and polymer temperature, manufacturers can take proactive measures to prevent or minimise this issue. In this blog post, we will delve into the intricate details of part warp, exploring its causes and effects on residual shear stress and shear rate. By demystifying these complex concepts and providing practical insights, we aim to equip manufacturers with the knowledge and tools necessary to effectively address part warp and ensure the production of high-quality plastic parts.

1. Understanding part warp: Causes and consequences

Understanding part warp is crucial in the manufacturing process, as it can have significant consequences on the final product’s quality and performance. Part warp refers to the distortion or deformation that occurs in a plastic component during the cooling process after moulding. It is a commonly encountered issue that can lead to dimensional inaccuracies, poor aesthetics, and even functional problems. Several factors can contribute to part warp, with pressure gradients and polymer temperature being two key influencers. Pressure gradients occur when there is an uneven distribution of pressure within the mould cavity during the injection moulding process. This can result from variations in material flow, gate design, or the filling pattern. High-pressure areas can lead to increased material flow, resulting in excess poly

mer filling certain regions of the mould cavity faster than others. Conversely, low-pressure regions can cause insufficient filling, leaving voids or thin sections. These imbalances in material distribution can lead to uneven cooling rates, which ultimately result in part warp. Polymer temperature also plays a crucial role in part warp. During the cooling phase, the polymer undergoes thermal contraction, which can cause distortion if not uniformly controlled. If sections of the part cool faster than others, thermal stresses build up and can cause warping. Factors such as material composition, mould design, and cooling mechanisms can influence polymer temperature distribution. The consequences of part warp can vary depending on the specific application and requirements of the component. It can result in dimensional variations, making the part incompatible with assembly or causing functional issues. Aesthetically, part warp can lead to visible deformities, surface defects, or even part failure. Understanding the causes and consequences of part warp is essential for manufacturers to implement effective mitigation strategies. This involves careful design considerations, including gate placement, mould design optimisation, and material selection. Additionally, controlling process parameters such as injection pressure, melt temperature, and cooling rate can help minimise the occurrence of part warp. By addressing pressure gradients and polymer temperature distribution, manufacturers can strive to produce high-quality components with minimal distortion and ensure optimal performance and customer satisfaction.

2. Pressure gradients: A key factor in part warp

When it comes to part warp in the manufacturing of plastic components, pressure gradients play a crucial role. Understanding and analysing pressure gradients can help demystify the causes behind part warp and provide insights into effective mitigation strategies. Pressure gradients refer to the variation in pressure experienced across different sections of a mould during the injection moulding process.

These variations can arise from a multitude of factors, including variations in polymer temperature, flow rate, and the design of the mould itself. The uneven distribution of pressure within a mould can lead to uneven cooling and solidification of the molten polymer, resulting in part warp. The variations in pressure can cause different rates of cooling and shrinkage across the part, leading to distortions and deformations. Analysing and managing pressure gradients is essential to minimise part warp. One effective approach is to optimise the design of the mould by incorporating features that promote uniform pressure distribution. This can include the strategic placement of cooling channels, the use of venting systems to release trapped air, and the implementation of proper gate design. Furthermore, careful monitoring and control of polymer temperature during the injection moulding process can help mitigate pressure gradients and minimise part warp. Maintaining consistent temperature throughout the mould cavity ensures uniform cooling and reduces the likelihood of uneven shrinkage. It is also important to consider the shear stress and shear rate experienced by the polymer during the injection moulding process, as they can influence pressure gradients and subsequently affect part warp. High shear stresses and rapid shear rates can result in non-uniform polymer flow, leading to uneven pressure distribution and subsequent part distortions. By understanding the correlation between pressure gradients, polymer temperature, residual shear stress, and shear rate, manufacturers can take proactive measures to mitigate part warp and enhance the overall quality of their plastic components. In conclusion, pressure gradients are a key factor contributing to part warp in the injection moulding process. Analysing and managing these gradients, along with considerations of polymer temperature, shear stress, and shear rate, can help manufacturers effectively address and minimise part warp issues, leading to improved product consistency and customer satisfaction.

3. Polymer temperature: Its impact on part warp

Polymer temperature plays a crucial role in the phenomenon of part warp. Understanding how it impacts the warping of plastic parts is key to achieving high-quality, dimensionally stable products. When a polymer is heated, it undergoes thermal expansion, causing it to expand in size. As the polymer cools down, it contracts, returning to its original dimensions. However, if the cooling process is not uniform or controlled properly, residual stresses can accumulate within the material, leading to part warp. The temperature at which the polymer is processed and cooled significantly affects the degree of part warp. If the cooling rate is too rapid, temperature gradients can form within the material, causing uneven contraction and resulting in warping. On the other hand, if the cooling rate is too slow,

Plastic components

the polymer may remain at elevated temperatures for an extended period, leading to excessive relaxation and potential warping as well. To mitigate part warp caused by improper temperature control, it is crucial to monitor and control the cooling process carefully. This can be achieved through techniques such as adjusting cooling rates, using cooling fixtures, or employing cooling media to facilitate uniform temperature distribution. Additionally, optimising the mould design and incorporating cooling channels can help regulate the polymer’s temperature and minimise temperature gradients. Furthermore, it is important to consider the polymer’s specific thermal properties during the processing stage. Different polymers have their own unique thermal behaviours, including their coefficient of thermal expansion and glass transition temperature. Understanding these properties and adjusting the processing conditions accordingly can help minimise part warp. In conclusion, the temperature at which a polymer is processed and cooled plays a significant role in part warp. By carefully controlling and monitoring the cooling process, selecting appropriate materials, and optimising mould design, manufacturers can minimise the effects of temperature gradients, reduce residual stresses, and achieve high-quality, dimensionally stable plastic parts.

4. Analysing residual shear stress and shear rate

When it comes to understanding part warp in manufacturing processes, analysing residual shear stress and shear rate is crucial. Residual shear stress refers to the internal stress that remains within a material after it has undergone deformation. Shear rate, on the other hand, measures the rate at which adjacent layers of a material slide past each other. Analysing residual shear stress and shear rate can provide valuable insights into the underlying causes of part warp. High residual shear stress indicates that there is excessive internal stress within the material, which can lead to deformation and warping. By identifying and addressing the factors contributing to high residual shear stress, manufacturers can mitigate part warp issues. Similarly, studying shear rate helps in understanding the speed and intensity at which material layers are moving relative to each other. A high shear rate can result in uneven material flow and increased internal friction, both of which can contribute to part warp. By analysing shear rate, manufacturers can identify areas of the manufacturing process where adjustments may be needed to minimise shear-induced warping.

injection moulding quality

To analyse residual shear stress and shear rate, various techniques can be employed, such as numerical simulations, experimental testing, and rheological studies. Numerical simulations involve using advanced software to model and simulate the behaviour of materials under different conditions, allowing for the prediction of residual shear stress and shear rate. Experimental testing involves subjecting materials to controlled conditions and measuring the resulting residual shear stress and shear rate. This can be done through techniques like mechanical testing, thermal analysis, or microscopy. Rheological studies involve analysing the flow behaviour of materials, particularly their viscosity and elasticity, which are directly related to shear stress and shear rate. Rheological measurements can provide valuable data on how a material responds to different levels of stress, temperature, and deformation, aiding in the understanding of part warp mechanisms. By analysing residual shear stress and shear rate, manufacturers can gain a deeper understanding of the factors contributing to part warp and develop targeted strategies to minimise its occurrence. This knowledge can lead to more efficient manufacturing processes, improved product quality, and reduced waste, ultimately benefiting both manufacturers and customers.

1. Importance of Runner System Design

The runner system is a crucial component in the injection moulding process and the injection moulding quality. A well-designed runner system can ensure consistent material flow and minimise defects. It is essential to consider factors such as gate types, gate locations, and runner size when designing the runner system. A small gate can lead to high injection pressure and poor part quality but does allow for a faster cycle time and the potential for self-trimming gates such as sub gates which reduce part cost. A large gate can increase cycle time and slow down production and will also need a separate trimming operation. Therefore, selecting the right gate type and location is critical for achieving optimal injection moulding quality.

2. The Role of Material Properties

Another essential factor that can affect material flow is the material properties. It is crucial to understand the viscosity and flow rate of the material being injected to optimise the runner system design. The material’s viscosity can impact the gate size, while a low flow rate can increase dwell time and affect the melt’s temperature. Therefore, it is essential to choose the right material and adjust the runner system design accordingly to achieve optimal injection moulding quality. The type of material is also a consideration a Crystaline or semi-crystalline material will behave very differently to an amorphous material, and this will often impact the gate and runner design and type chosen for the application.

3. Simulation Software

Simulation software can aid in designing a runner system by predicting the flow of the material within the mould. It allows designers to simulate various scenarios and optimise design parameters before creating the final mould. By simulating the injection moulding process, designers can predict potential issues such as weld lines, air traps, and flow hesitation. This approach helps in reducing the iterations required during the mould design process and optimising the runner system design for optimum injection moulding quality.

4. Sustainable Runner System Design

In recent years, there has been a growing interest in sustainable manufacturing practices and reducing waste in the injection moulding process. Runner systems can contribute to material waste, as they are often discarded after each cycle. One solution is to design a cold runner system, where the runners are not ejected with the part and can be re-processed and fed back into the machine to use in subsequent cycles. Another option is to create a hot runner system, where the runner material is kept melted and reused in the next cycle, reducing waste and energy consumption. Sustainable runner system design not only benefits the environment but can also lead to cost savings and increased efficiency.

5. Runner Balancing

Balancing the runner system is crucial for achieving consistent material flow and preventing defects in the final product. This stage is often overlooked by toolmakers and imbalanced runners can lead to variations in filling time and pressure, causing issues such as short shots, sink and warpage. Balancing the runner system involves adjusting the runner length, diameter, and placement to ensure equal pressure and material flow to each cavity. This process can be time-consuming but is essential for achieving optimal injection moulding quality.

6. Design for Manufacturability

Design for manufacturability (DFM) is a concept that involves designing parts and moulds that are optimised for the injection moulding process. By considering DFM principles, designers can ensure that the part is mouldable, with appropriate wall thickness, draft angles, and gating locations. These factors can impact the runner system design and ultimately affect the part’s quality. Designing for manufacturability can reduce lead times, decrease costs, and improve quality control in the injection moulding process.

In summary, controlling material flow in a runner system is crucial to achieving optimal injection moulding quality. A well-designed runner system, consideration of material properties, simulation software and using well-established practices to ensure the runner is designed properly, can significantly impact the final product’s consistency and quality. Optimising the injection moulding process requires a thorough understanding of the runner system and its role in the overall process. By following these guidelines, engineers, product designers, mould designers, toolmakers, and mould makers can improve their injection moulding processes and achieve consistent, high-quality results.

In conclusion, there are various factors to consider when designing a runner system for injection moulding. optimising the runner system design can result in consistent material flow, reduced defects, and improved product quality. Using simulation software and designing for sustainability and manufacturability can also improve the injection moulding process’s efficiency and reduce waste. Balancing of the runner system is also crucial for ensuring optimal quality and preventing downtime. By following these guidelines, manufacturers can achieve consistent, high-quality results in their injection moulding processes.

9. Addressing common misconceptions and myths

In the world of plastic manufacturing, there is a long-standing debate that has puzzled many: the spelling of “moulding” versus “molding.” This confusion has sparked numerous misconceptions and myths that often leave manufacturers scratching their heads.

One common misconception is that the choice between “moulding” and “molding” is simply a matter of regional preference. While it is true that the spelling can vary depending on the country or region, there are deeper factors at play.

The first myth we need to debunk is that “moulding” is the British spelling, while “molding” is the American spelling. While it is true that “moulding” is more commonly used in British English, it is not exclusive to this region. In fact, both spellings have been used interchangeably in various English-speaking countries.

Another misconception is that the spelling difference reflects a distinction in the manufacturing process. Some believe that “moulding” refers specifically to the process of shaping plastic using a mould, while “molding” refers to a broader range of manufacturing techniques. However, this is not accurate. The choice of spelling does not indicate any difference in the actual manufacturing process.

To further complicate matters, there are industry-specific terms that can contribute to the confusion. For example, in the construction industry, “molding” often refers to decorative trim or casing, while “moulding” is used to describe the process of creating these decorative elements. This usage can vary across different industries, adding to the complexity of the debate.

Ultimately, it is essential for manufacturers in the plastic industry to understand that the choice between “moulding” and “molding” is subjective. It depends on factors such as personal preference, regional conventions, and industry-specific terminology. What matters most is clear communication within the industry and a shared understanding of the intended meaning.

By addressing these common misconceptions and myths, we can untangle the spelling confusion surrounding “moulding” and “molding” in the plastic manufacturing industry. Let’s prioritise effective communication and focus on the quality of our products rather than getting caught up in a never-ending debate over spelling.

10. Conclusion: Embracing language diversity and clarity in the industry

In conclusion, the ongoing debate between “moulding” and “molding” in the plastic manufacturing industry can be seen as a testament to the diversity of language and the importance of clarity in communication.

While some may argue for the traditional spelling of “moulding,” emphasising its historical roots and adherence to British English, others may advocate for the simplified spelling of “molding,” which aligns with American English conventions and is increasingly accepted worldwide.

Rather than getting caught up in the spelling differences, it is crucial for professionals in the plastic manufacturing industry to prioritise clear and effective communication. This means ensuring that all stakeholders, regardless of their geographical location or preferred spelling, can understand and interpret the information accurately.

By embracing language diversity and accommodating different spellings, the industry can foster inclusivity and avoid any unintended misunderstandings. It is essential to establish clear guidelines and standards for terminology within the organisation to maintain consistency and prevent confusion.

Ultimately, the focus should be on the quality of the products and services provided by the plastic manufacturing industry rather than the spelling nuances. By prioritising effective communication and embracing language diversity, professionals in the industry can navigate the “moulding vs molding” debate with ease while focusing on delivering excellent results to their customers.

We hope this blog post has shed some light on the great moulding vs molding debate in the plastic manufacturing industry. While the spelling may differ depending on geographic location, it’s important to remember that both terms refer to the same process.

How Plastic Moulders are Improving Production Efficiency in Injection Moulding with Robotic Automation

In today’s fast-paced injection moulding industry, companies are constantly seeking ways to improve production efficiency and gain a competitive edge. With the advent of robotic automation, injection moulding companies can now streamline their operations, enhance product quality, and increase overall productivity. In this article, we will explore the various ways in which robots can and have improved the production efficiency of injection moulding, at Ledwell, along with the benefits they bring to the table.

The Rise of Robotics in Injection Moulding

The demand for more flexible solutions in the plastics industry has led to the extensive use of industrial robots in injection moulding operations. These robots can automate the entire injection moulding process, from loading plastic parts into the machine to placing the finished products onto a conveyor belt. By replacing human-operated injection moulding with robots, companies can ensure the consistent production of high-quality products that are accurately formed.

Advantages of Robotic Automation

The utilisation of robotics in injection moulding offers several advantages for manufacturers. Firstly, it provides them with a competitive advantage by increasing both productivity and the quality of the produced parts. Robots can work faster and more efficiently than humans, leading to higher output and reduced cycle times. Additionally, robots can perform highly repetitive tasks 24/7 without the need for breaks or rest, maximising the utilisation of injection moulding equipment and increasing overall efficiency.

Another significant advantage of robotic automation is the improvement in product quality. Robots can perform precise and repeatable tasks, ensuring consistent quality and reducing the risk of errors or defects. They can also handle parts in a controlled and consistent manner, reducing the risk of contamination and improving the overall quality of the final product. By incorporating robots into the injection moulding process, manufacturers can reduce waste, minimise the need for rework or scrap, and deliver products that meet the required specifications.

Application of Robotics in Injection Moulding

Robots have a wide range of applications in different stages of the injection moulding process. One common application is machine tending, where robots are used to unload finished parts from the injection moulding machine and deliver them to downstream processes such as packaging. By automating this task, manufacturers can improve product consistency, reduce the risk of injuries to labourers, and increase production capacity.

Another important application is insert moulding, which involves enclosing inserts such as pins or threaded rods in moulded plastic. Robots, such as SCARA robots, can add inserts to mouldings and load them into machines to continue the process. They can also work in collaboration with pick-and-place robots to complete the manufacturing process.

Automation can also be applied to over-moulding, where a moulded object is removed from one injection moulding machine and placed into another with the help of a robot. This automated process ensures a more efficient and accurate arrangement of parts, reducing labour and assembly expenses while ensuring the quality and integrity of the final product.

In-mould labelling is another popular application for automation in injection moulding. Robots can feed pre-printed labels or decorated film directly into the open plastic injection mould, ensuring precise and stable positioning of labels. This process enhances the visual appeal of the final product and eliminates the need for secondary processing or shipping parts to and from warehouses.

Post-processing tasks, such as inspection, testing, and trimming of plastic moulded parts, can also be automated using robots. Robotic trimming cells provide superior repeatability compared to manual trimming, resulting in higher precision, accuracy, and cycle times. Robots can minimise waste and improve production efficiency by reducing errors and defects.

The Future of Robotic Technology in Injection Moulding

The future of robotic technology in injection moulding looks promising, with ongoing advancements aimed at simplifying operations and maximising overall equipment effectiveness. Companies like Sepro Group are breaking new ground in the area of robot and automation control. Their work focuses on simplifying robot programming with the use of artificial intelligence (AI) and creating highly integrated control systems that communicate with all equipment in a production cell.

Plastic moulders can overcome the technical complexities associated with robot programming by implementing “no-code” programming and AI-driven robot controllers. This enables easier retrofitting of code or hardware to evolving business and market needs, making robotic automation more accessible and user-friendly. As a result, even relatively new employees with limited training can set up basic moulding processes, further reducing the need for skilled technicians.

In conclusion, robotic automation offers immense potential for improving production efficiency in injection moulding. Manufacturers can increase productivity, enhance product quality, and reduce costs by utilising robots in various stages of the process. Robots’ flexibility, precision, and efficiency contribute to the overall competitiveness of injection moulding companies. As technology advances, the future of robotic automation in injection moulding looks promising, paving the way for further innovations and improvements in the industry.

Plastic injection moulding

Advantages of Injection Moulded Parts:

 

1.0 High Efficiency:

One of the biggest advantages of injection moulding is its high efficiency in producing plastic parts. The process involves feeding raw plastic material into a heated barrel, which is then melted and injected into a moulding cavity. The entire process takes just a few seconds, during which time multiple parts are moulded.  With good mould tool design and under the right circumstances different parts can be produced simultaneously. As a result, injection moulding is highly efficient and reduces the cost per part.

 

2.0 Repeatability:

Another advantage of injection moulding is its ability to produce identical parts with high repeatability. This is due to the computer-controlled IM machinery, giving a consistent and repeatable process.  This results in consistently shaped parts. As a result, the parts produced through injection moulding can be easily assembled with high levels of interchangeability, in various applications.

1.0 Start-up Costs:

The biggest disadvantage of injection moulding is the start-up costs associated with the machinery, moulds, and equipment required. The cost of creating the moulding tools and setting up the initial process can be high, making it challenging for manufacturers looking for low-volume production runs. There are options to help with tooling cost reduction including the “Ledwell Plastics Rapid Tooling System”.  However, due to the nature and requirements of the process, this cost does still need to be overcome.

 

2.0 Limited Material Compatibility:

An additional disadvantage of injection moulding is that it is limited to material compatibility. Certain materials cannot be easily processed through injection moulding.  The design of components and parts needs to be considered carefully to make sure it is possible to produce them in the desired polymer. The choice of the wrong materials for components and parts that work together within an assembly may result in certain parts not functioning as they should. Careful consideration of the materials used needs to be addressed at the design and prototype stage to ensure cross-compatibility and correct product operation. Temperature is a part of this too.  Although there are polymers that can withstand high temperatures they can often limit the design of the part due to the difficulty in processing them. Manufacturers must carefully consider the material selection before opting to use injection moulding.

 

3.0 Design Limitations:

Finally, injection moulding has design limitations that need to be considered when developing components. Often with thought and by working with an injection moulding company workarounds or design tweaks can overcome these limitations. Simply put the injection moulded parts must be designed with the moulding process in mind, and this can limit what designers can achieve creatively. Additionally, parts produced by injection moulding may require additional post-production processing, which may increase the overall cost.

 

Conclusion:

Injection moulding has many advantages, but these need to be weighed against the associated costs and limitations. Engineers must carefully consider their design requirements and materials, but working with an injection moulding company with sound knowledge of the process and limitations can often resolve such issues.  By fully understanding the advantages and disadvantages of injection moulding, engineers can make informed decisions for their projects, both in terms of design and cost-efficiency.

Ledwell Expands Quality Control | Meet Paige

Posted on by Peter Wilkinson

Quality Control in the Field of Injection Moulding: An In-Depth Guide

Paige Otter- quality control Injection moulding
injection moulding

Injection moulding assembly

**Paige Otter, Ledwell’s Quality Control Supervisor

Injection moulding, a cornerstone manufacturing process, has been the backbone of the plastic industry for decades. It’s a complex procedure that requires precision, expertise, and strict quality control measures. This post delves into the quality control aspect of injection moulding, highlighting its importance, the procedures involved, and the benefits it offers.

The Art of Injection Moulding

Before diving into quality control, let’s understand the process of injection moulding. It’s a technique where molten plastic or composites are forced into a mould to create a part, a product or component. There is a wide range of different plastics to choose from as well as composites and biodegradable materials. The process begins with the material being heated until it becomes molten. It’s then injected into a mould under pressure, cooled to solidify, and eventually removed from the mould. The result is a solid part fashioned and engineered from your chosen material.

Injection moulding technology came into existence in the early 1870s, initially used to manufacture billiard balls. Fast forward to today, and injection moulding has become a versatile method to create a plethora of products – from drink tumblers and automotive parts to musical instruments and medical devices.

The Vital Role of Quality Control in Injection Moulding

In the world of injection moulding, quality control is crucial. It’s a systematic process that ensures the final products meet the set specifications and consumer expectations. Several factors, including dimensional stability, colour, gloss, and moulding defects, define how well the product aligns with the intended design and overall quality.

Quality control is not just a term used to boost brand image or a buzzword thrown around casually. It’s a rigorous process that involves meticulous planning, design, development, assembly, production, and packaging. Quality control measures are integral to the success of a business, reducing production costs and boosting customer satisfaction.

Dimensional Stability and Quality

Dimensional stability is an important aspect of quality control. If the product is an individual piece that doesn’t connect to anything, the dimensions might not matter. However, for components that fit together to form an assembled product, having the correct dimensions is crucial.

Each component must conform to specific dimensions to fit with other parts correctly. This includes being neither too large nor too small and maintaining the right shape to fit, perfectly with other components. If the components don’t fit together, the entire assembly might not function as intended, resulting in halted manufacturing lines or dissatisfied customers.

The Impact of Colour in Injection Moulding Quality Control

Colour is another critical factor that can affect the overall quality of the product. Changing process parameters, such as increasing or decreasing temperature and pressure, can affect the end colour of the product. There are different ways to colour the plastic, including pre-coloured plastic from a plastics manufacturer or a blended plastic created at the moulding factory.

Colour harmony is crucial to ensure each component meets the specification, meaning each part aligns with the intended colour within a few shades. It’s important to show uniformity and consistency of colour between all components, meeting the design intent.

The Role of Gloss in Product Quality

Gloss, though a small detail, can significantly influence the perceived quality of the product. The right gloss level can enhance your product’s visual appeal, influencing your consumer’s perception. The process parameters during moulding can influence gloss to a certain degree. For instance, high temperature may increase gloss, while the time in the mould could decrease the gloss level of your product.

Common Moulding Defects and Quality Control

Moulding defects can affect the quality of your product. The five most common defects that may occur include flow/weld lines, sink marks, short shots, burn marks, and flashing. Each of these defects can compromise the overall quality of the product, deterring customers from purchasing it.

However, not all defects warrant discarding the product. For instance, some defects might be acceptable on an internal component that isn’t visible after assembly. The product specification should outline if a defect is acceptable, its acceptable location, and the degree of defectiveness allowed.

Benefits of Quality Control in Injection Moulding

Quality control in injection moulding comes with numerous benefits. It encourages a quality-conscious approach among the workers, leading to higher product quality. It also reduces production costs by minimising waste and inefficiencies. Companies can ensure the utilisation of resources, improve employee morale, and satisfy customers by maintaining stringent quality control measures. Additionally, quality control helps identify and fix problems early, reducing returns and failures.

Quality Control Trends: AI and Advanced Quality Assurance Tools

Quality control in injection moulding has seen significant advancements with the emergence of artificial intelligence (AI) and advanced quality assurance tools. AI enables complex and reliable quality control systems, ensuring consistency in mass production. The integration of AI with quality control systems allows automatic adjustments to the moulding cycle, improving the overall production process.

In addition to AI, advanced quality assurance tools like IdentiPol QA2 have revolutionised quality control in injection moulding. It enables efficient quality assurance tests, ensuring consistency and quality across the production line. It’s a user-friendly tool that grades plastics based on a pass or fail basis, bridging the gap between simple testing and complex lab analysis.
