Injection Moulding

Injection Moulding Case Study

The component shown above was originally machined in plastic. This is now overmoulded in Hytrel which is a soft rubber like material. The advantages are cost, flexibility and no fretting at the cable joint.

Machining parts in plastic is a good way to produce low volume components that have the right electrical and mechanical properties to be able to carry out test work and manufacture working models. Injection moulding is a very flexible process that allows complex shapes to be manufactured with a high degree of accuracy and repeatability.

Various components can be joined together by over moulding them with plastic. We have many examples where component costs have been reduced significantly by moving to injection moulding.

The expertise is in the design of the product, which is why we offer design support to make sure that the customer gets the best process for their products.
