Injection Moulding Plastics: How to Improve Flow Lines 

Injection Moulding Plastics: How to Improve Flow Lines 

Injection moulding plastics is a widely used manufacturing process for creating high-quality plastic parts. However, like any process, it is not without its challenges. One common issue that arises during injection moulding is the occurrence of flow lines. Flow lines are wavy patterns or streaks that appear on the surface of moulded parts, resulting from uneven material flow and cooling. While flow lines may 

not affect the functionality of the part, they can impact its aesthetic appeal. In this article, we will explore the causes of flow lines in injection moulding and discuss strategies to prevent and minimise their occurrence. 

Injection Moulding Plastics

Understanding Flow Lines in Injection Moulding Plastics

Flow lines are visual defects that manifest as circles, lines, or patterns on the surface of a moulded part, predominantly near the gate where the material enters the mould cavity. These lines are an indication of non-uniformity in the flow pattern of the molten plastic within the mould. When the molten material reaches a cooled area of the mould, it solidifies, while the material in the inner area continues to flow. This temperature difference between the flowing and solidified material results in a ripple-like effect, causing flow lines to appear. 

While flow lines can provide insights into the material flow and fill behaviour within the mould, they are generally considered undesirable. Customers and manufacturers prefer visually flawless parts with high aesthetic standards. Flow lines can be particularly problematic for parts that require a smooth surface, such as gears. Therefore, it is cruc

ial to address flow lines through proper process and mould design to ensure the production of high-quality plastic parts. 

Causes of Flow Lines in Injection Moulding Plastics

Flow lines can occur due to various factors, including material properties, machine settings, and mould design. Understanding these causes is essential for implementing preventive measures. Let’s explore some common causes of flow lines: 

Material Temperature 

The melt temperature of the plastic material plays a significant role in controlling its viscosity and flow characteristics. If the melt temperature is too low, the material may not flow uniformly, leading to flow lines. It is important to heat the plastic to an optimal temperature that allows for proper deformation and flow. However, caution must be exercised to avoid exceeding the degradation temperature of the material. Monitoring temperature at different points in the injection moulding process using temperature sensors and employing control systems and alarms can help prevent flow lines. 

Mould Temperature 

The temperature within the mould can also contribute to the formation of flow lines. If the mould temperature is too low, premature cooling may occur when the molten material enters the mould cavity. This can result in uneven flow and the appearance of flow lines. Adjusting the mould temperature to ensure proper heat transfer and preventing premature cooling can help minimise flow lines. 

Injection Speed and Pressure 

The speed and pressure at which the molten material is injected into the mould also affect the occurrence of flow lines. Insufficient injection speed or pressure can cause slower flow, resulting in parts of the material solidifying before others. This temperature difference in the flow pattern leads to the formation of flow lines. Increasing the injection speed and pressure

Injection Moulding Plastics

 can help maintain uniform flow and minimise flow lines. 

Runner and Gate Design 

The design of the runner and gate in the mould can significantly impact material flow and the occurrence of flow lines. A narrow runner or gate restricts flow, slowing down the material and exposing it to increased temperature loss. This can result in non-uniform cooling and the appearance of flow lines. It is important to ensure that the runner and gate dimensions are appropriately sized to allow for smooth and even flow throughout the mould cavity. 

Preventing Flow Lines in Injection Moulding 

Preventing flow lines requires a combination of careful mould design and proper adjustment of process parameters. Here are some strategies to consider: 

Optimise Mould Design 

A well-designed mould is essential for minimising flow lines. Maintaining uniform wall thickness throughout the moulded part is crucial to ensure consistent cooling and prevent temperature variations that lead to flow lines. Avoiding sharp corners and incorporating smooth bends in the design can promote even material flow and reduce the occurrence of flow lines. Additionally, proper gate placement and type selection can help distribute material evenly, reducing the likelihood of flow lines. 

Control Process Parameters 

Controlling process parameters during injection moulding is vital for preventing flow lines. It is important to ensure that the melt temperature is within the recommended range for the chosen material. Adjusting the mould and nozzle temperature to maintain optimal heat transfer and prevent premature cooling can also minimise flow lines. Increasing injection speed and pressure can help maintain uniform flow and prevent temperature variations that lead to flow lines. Furthermore, ensuring proper venting in the mould can help eliminate trapped air and promote even material flow. 

Post-Processing Treatments 

In some cases, even with careful mould design and process optimisation, flow lines may still appear on the surface of the moulded parts. In such situations, post-processing treatments can be employed to minimise their appearance. Texturing the mould surface can help hide flow lines, as they are more visible on smooth surfaces. However, it is important to consider the functional requirements of the part before applying texturing treatments. Painting and pad printing techniques can also be used to mask flow lines and improve the aesthetic appeal of the parts. 


Injection Moulding Plastics: How to Improve Flow Lines

Flow lines are a common defect in plastic injection moulding that can impact the visual appeal of moulded parts. Understanding the causes of flow lines and implementing preventive measures through proper mould design and process optimisation is crucial for producing high-quality plastic parts. By optimising material and mould temperatures, adjusting injection speed and pressure, and ensuring proper venting and gate design, manufacturers can minimise the occurrence of flow lines. Additionally, post-processing treatments such as mould texturing, painting, and pad printing can help mask flow lines and enhance the aesthetic quality of the parts. By addressing flow lines, manufacturers can meet the demands of customers for visually flawless plastic products.

Determining the injection mould cost is not a straightforward task as it is subject to various factors. Considering all the variables involved is crucial in evaluating the overall cost of the injection mould. One must carefully weigh the cost of the mould against the number of parts being manufactured. Producing higher quantities of parts will result in a lower per-piece cost, as the total injection mould cost can be distributed over hundreds or thousands of pieces. Despite the initial expense, injection moulding remains the quickest and most cost-effective method for producing large quantities of plastic parts.

How to Calculate Injection Moulding Cost. 

The cost of plastic injection mould tooling largely relies on the machining of the injection mould. Several factors come into play when determining the cost. The complexity of the mould is the key element in the cost of the tooling, the size of the mould is also a significant factor in its cost. Larger and more intricate moulds will naturally be more costly compared to smaller and simpler moulds. Additionally, the type of mould influences its price. Prototype injection moulds typically cost less than moulds used for production runs. On the other hand, moulds intended for long production runs will incur higher expenses. To withstand repeated use during extended production, these moulds need to be constructed from strong, high-strength, fully hardened steel, steel such as P20 or anti-corrosion stainless steel. How the part is going to be fed is an often-under-considered factor as well.  This could be from a myriad of different cold feed options or if the need arises a hot feed may be necessary to suit your application. Gate vestige, gate size and plastic runner waste factor need to be considered so we understand what type of runner and feed is ideally suited to the product.

The number of injection cavities built into the mould is the final factor to consider. High-production moulds often have multiple, identical injection cavities, known as multi-cavity moulds. Meanwhile, family moulds feature two or more similar cavities that may not be identical. An example is moulds producing the right and left sides of a part that snap together. These moulds consist of multiple cavities that produce the same part or related parts in a single press, reducing the frequency of opening and closing the mould while enhancing production efficiency. 

The following are some of the questions that will need answering to enable the best price solution for your project: –

  • How many products do you require per batch and per annum? 
  • Do you know what material you may want to use, if not can you explain the function and ergonomic requirements of the product and we can offer advice?
  • Part colour, does this need to be a specific RAL colour, or colour-matched? 
  • Expected total life for the product? 
  • Do you have any specific tooling specification requirements?  
  • What is the expected surface finish for the part?  
  • Is the part design open for change to help us to offer you a cheaper longer lasting, better overall solution for the mould tooling?  
  • Do the parts need to comply with any regulations, such as fire-retardant UV degradation? 
  • Are there any other factors that may influence the parts going forward that may need to be considered? 
  • Do you require prototypes? 
  • Do you require design advice and help?

Injection Moulding Process – The Vital Role of Mould Temperature

Injection Moulding Process and Mould Temperature

Plastics Injection Mould Tool

Injection moulding is a popular technique in manufacturing, enabling the production of a vast array of components with intricate designs and diverse materials. Given the efficiency of the injection moulding process and its adaptability, it is used across numerous sectors, including automotive, electronics, and healthcare.

One of the most important aspects of injection moulding is mould temperature, this factor can significantly impact the quality of the production and the parts that are being produced. Effective temperature control is critical for preventing quality issues such as shrinkage, stresses and warping from developing in the plastic. It is important that a balance between temperature of the cooling fluid and the rate of mould cooling is controlled.

This article delves into the importance of mould temperature in the injection moulding process, exploring its influence on the various stages and the resulting outcomes.

Defining Mould Temperature

Mould temperature refers to the temperature of the mould surface itself. It is a crucial factor during the injection moulding process as it determines how the product heats up and cools down. This temperature fluctuation significantly affects the final look, feel, and quality of the product.

Importance of Mould Temperature Control

The precision of mould temperature control is a vital aspect of the injection moulding process. The goal is to maintain the mould surface temperature within a specific range to ensure optimal conditions for the plastic material to flow, fill the mould cavity, and solidify into the desired shape.

The mould temperature is typically controlled using cooling or heating channels within the mould. These channels carry a coolant, often water, that regulates the mould’s temperature by either removing or adding heat. The design of these channels, including their diameter, number, location, and distance from the mould’s surface, is crucial to the performance of the moulded part.

Mould Temperature and Material Behaviour

The mould temperature plays a significant role in determining the behaviour of the plastic during the injection moulding process. For instance, in amorphous polymers like Acrylonitrile Butadiene Styrene (ABS) and polycarbonate, higher mould temperatures result in lower levels of moulded-in stress. Consequently, the final product has better impact resistance, stress-crack resistance, and fatigue performance.

On the other hand, in semi-crystalline plastics, the mould temperature is a key factor in determining the degree of crystallinity in the polymer. The degree of crystallinity influences many performance parameters, including creep resistance, fatigue resistance, wear resistance, and dimensional stability at elevated temperatures.

Mould Temperature and Injection Pressure

The mould temperature also impacts the injection pressure required during the injection moulding process. The injection pressure is the force that propels the plastic to flow, and it varies depending on the mould temperature. A higher mould temperature reduces the viscosity of the molten plastic, making it easier to flow and fill the mould. Conversely, a lower mould temperature increases the plastic’s viscosity, requiring a higher injection pressure to fill the mould.

Mould Temperature and Injection Time

Another critical parameter influenced by mould temperature is the injection time, which refers to the time taken for the plastic melt to fill the cavity. The injection time must be carefully adjusted according to the mould temperature to ensure that the mould is completely filled before the plastic solidifies. This precision in setting the injection time is crucial for improving the surface quality of the products and reducing dimensional variance.

Importance of Mould Locking Pressure

To resist the injection pressure, it is necessary to use mould locking pressure. The objective is to calculate a suitable value considering the projected area. The projected area of injection moulded parts is the maximum area seen from the direction of the clamping force. The appropriate mould locking pressure helps to maintain the integrity of the mould and ensure that the moulded part accurately represents the design.

Back Pressure and Its Role

Back pressure refers to the pressure that must be produced and exceeded before the screw retreats. Although a high back pressure is beneficial for pigment dispersion and plastic melting, it prolongs the screw’s return time, reduces the length of the fibre in the filled plastic, and increases the stress on the injection moulding machine. Therefore, the back pressure should be as low as possible, generally not exceeding 20% of the injection pressure.

Mould Temperature and the Cooling Process

A significant phase of the injection moulding process influenced by mould temperature is the cooling process. The objective of the cooling process is to lower the temperature of the moulded plastic to the point where it solidifies. Once the plastic solidifies, it can be demoulded. The cooling process needs to be carefully controlled to minimise warpage, twisting, or other shrinkage-related problems.

Mould Temperature and Its Impact on Final Products

The mould temperature significantly affects the final properties of a moulded product. A product cooled too quickly could become brittle and crack under pressure or force. On the other hand, slow cooling could result in a part with lower stress resistance and a higher propensity for warping or distortion. Hence, the mould temperature should be carefully regulated to balance these factors and produce a high-quality moulded part.

Key Takeaways

In conclusion, mould temperature plays a pivotal role in the injection moulding process. It influences the behaviour and transformation of the material, the injection pressure and time, the cooling process, and the final properties of the moulded part. By carefully controlling the mould temperature, manufacturers can optimise the injection moulding process to produce high-quality, durable, and precise moulded parts. Therefore, understanding and managing mould temperature is a critical aspect of successful injection moulding production.

Injection Moulded Parts | Advantages and Disadvantages

Injection Moulded Parts | Advantages and Disadvantages

Injection Moulded Parts | As engineers, we know that choosing the best manufacturing process for a particular product is crucial for its success in the market. Injection moulding is a widely used manufacturing process for producing plastic parts due to its high efficiency, repeatability, and ability to produce complex shapes. However, like any manufacturing process, it has its advantages and disadvantages that need to be carefully considered before implementation. In this article, we will analyse the advantages and disadvantages of injection moulding, providing a comprehensive understanding of this process for engineers seeking to make informed decisions for their projects.

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.


3.0 Production of complex shapes:

Injection moulding enables the creation of complex and intricate shapes that may be challenging to produce through other manufacturing techniques. The ability to produce parts with such complex geometries opens up exciting opportunities in various industries, including automotive, medical, and consumer electronics.


Disadvantages of Injection Moulded Parts:


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.



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

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

**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.
