As your concept progresses through the design and development phases, it’s important to think about how you want your product to be manufactured. If you’re looking to produce it in a large volume, then injection moulding can be the way to go.

What is injection moulding?

Injection moulding is a manufacturing process for producing parts in a large volume. It’s typically used in mass production, where the same part is being made over and over again. It’s also the most popular method of producing large quantities of plastic parts.

Why should you use injection moulding?

The main advantage of injection moulding is the ability to mass produce your product to the same quality each time.

Other advantages, include: 

  • Low price per unit 
  • Low relative waste being an additive manufacturing process
  • Fast cycle time per part
  • Low labour cost
  • Easily repeatable process 
  • Produces consistent and reliable parts 
  • Suitable for high volume production
  • A high variety of materials and finishes

Am I ready for injection moulding?

Before deciding to use injection moulding for your product, it’s important to think about whether your design is ready. If you’re going to produce your part in high volumes, it needs to be correctly designed (see our Guide to Product Design here) or you will run into extra costs involved with post-production labour such as trimming of excess plastic (called flashing), unnecessary cutting of persistent sprues, or manual removal of parts when they don’t eject properly. Inconsistent ejection is a massive source of increased costs, as then the machine needs to be constantly manned and cannot be left to run overnight. This happens all too often with products that may be designed amazingly for aesthetics and user functions, but poorly for manufacturing.

Sometimes these issues can be solved with modifications made to the moulds and tool, though this can be highly costly, and is not always possible. For these reasons, it is important to spend the correct time and effort in the design, prototyping and tooling stages. Making sure you iron out all the kinks as early as possible to avoid costly modification later on.

Our designers are specifically trained in product design and design for injection moulding. With the added bonus of having a working tool making workshop and injection moulding shop along with qualified Toolmakers and Injection Moulders at their disposal. This makes the overall design process more efficient and economical than that of a design house without our intimate and hands-on manufacturing experience.   

In summary, injection moulding is a great technique for finished production on a large scale.
