Why use expensive external design services?

Design for plastic injection moulding requires a certain approach and working with Rutland Plastics saves time and money and results in suitable plastic moulding designs from the outset.

Here at Rutland Plastics we work in partnership from initial concept, through the injection moulding design stage using 3D CAD, to the making of the injection mould tool.  All through that process, we share our expertise with customers and together we optimise the choice of plastic material, physical shape, ease of production, cost and performance.

We advocate that you take the opportunity to tap into this technical support early in the design process because it helps de-risk the project thus avoiding costlier modifications at a later stage.

We believe in working in partnership with you, acting as an extension of your own technical department. Working together we can find the best injection moulding solution.

In addition to the wealth of information freely available on our website, you can call us at anytime for help with your project.

We listen to what you want and work with you to achieve the results you need. Most of all it means delivering on our promise to you – every time.


There are many things to consider when designing for injection moulding. That’s why our experts are here to help.  Rutland Plastics uses VISI Flow software to fine tune new mould designs, therefore, ensuring cost effective and reliable designs from the outset.


Prototypes can also be arranged. Rutland Plastics has its own 3D printer capable of producing rapid plastic prototypes which will closely resemble the final injection moulded parts enabling you to fully test the part prior to investing in tooling.

Design Guidelines

Designing for plastic injection moulding requires special consideration.  We have a series of articles covering designing for Injection Moulding. To read more about our design guidelines please click here.


With more than 60 years experience in the injection moulding of plastic components, we can provide advice and quotes on anything from a simple sketch to a 3D computer model.
