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?

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.

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.
