Moulding

Polytech Mouldings are a market leading specialist in the injection and cast moulding of engineering plastics. As a supplier to engineering and manufacturing companies, we are trusted to supply high quality, high performance moulded parts.

We offer flexible manufacturing options and our broad range of materials enable us to adapt our solutions to suit specific applications and operating environments.

Our experience and comprehensive technical knowledge allow us to advise, support and provide recommendations at every stage of the process.

For further information regarding our onsite tool manufacturing service please see our Toolmaking page.

Injection Moulding

For years, injection moulding has been our primary manufacturing option. Our injection moulded components are used heavily across all industrial sectors due to the diversity of the base materials we offer including Polyurethane, Nylon, Polypropylene, TPE and TPR, and the variety in size and shape that can be moulded.

Injection moulding is the ideal process if you are looking for an efficient, high volume manufacturing option.

Our full bespoke service from initial concept or simple sketch, right through to full production runs and delivery, allows us to work collaboratively with you on new or existing projects.

It is important to discuss the key application requirements and critical profile details, as there are often numerous material and production options available. High volume parts may be more suited to multi cavity or hardened moulds, which may result in higher upfront costs but can result in long term savings in reduced unit costs. Equally, where suitable, bigger tolerances and allowances on surface finish may enable more cost-effective production options that suit the required part more appropriately.

Cast Moulding

Polytech Mouldings’ cast moulding department allows larger and heavier parts to be manufactured than through the injection moulding process. It also allows for the production of “standard” products such as Polyurethane Rods, Polyurethane Blocks, Polyurethane Rollers and Polyurethane Seals.

Cast moulding is ideally suited to lower production volumes than injection moulding and is limited to polyurethane in terms of material options. However, due to the diversity of this engineering plastic there are several different material grades that can be used which allows us to help identify the most suitable choice for the product’s operating environment.

A flexible and responsive approach allows us to manufacture temporary moulds from sample products, providing efficient prototyping and cost-effective solutions for low-medium volume production.
