Design support

We offer design support for tooling manufacturing and plastic injection moulding.
The WSM Plastics development team are first class in the field and combine great skills that complement each other perfectly. They go beyond the scope of the brief and offer solutions
to various design issues that may arise.

Providing a high level of support right at the start of your project which begins on receipt of your enquiry, we can provide you with a Design For Manufacture (DFM) review of your component. At the earliest stage of the DFM process, we will focus on ease of manufacture and optimal mould tool configuration.

Component design

If you have an idea for a product or component but do not have it fully developed into a CAD model or 2D drawing, WSM Plastics can work with you to turn just a simple sketch into a finished product.

Our designers will work with you to refine your design, enabling you to optimise the best processes for manufacture, cost efficiency and achieve the best quality part.

Tool design 

Designing the right tooling for plastic injection moulding production is an important step in the product development process. Our team of experts support our customers with design in both complex and standard mould tools.

We work closely with our customers during each stage of the tooling process. As each part is project managed, we hold regular reviews to ensure that our customers receive the best quality tool their component deserves.

All your tool designs are compiled on SolidWorks, with our customers receiving a full drawing pack and mould setting details on completion of the tool design and manufacture.

To provide you with the best-performing tool, our team runs a software programme called a Mould Flow Analysis (MFA) before the tool goes into manufacture. This simulates how a component will react when moulded. From this, we are able to determine if we need to make any changes to a component tool design before we start the manufacture of the tooling. This will ensure precision and quality.

Our team is always on hand to liaise with our customers during the entire process. Once the design has been finalised, the project can move onto the tool manufacture phase.
