Injection Moulding

Extensive range of materials:

Cox Plastics are able to mould in a wide range of commodity materials and engineering plastics. Through extensive consultation we can advise you on the best choice of material for your application.

Component design facilities:

We offer a full component design consultancy as well as stereolithographics, vacuum casting and prototyping.

As part of our commitment to staying at the leading edge of moulding technology Cox Plastics have invested in Moldflow™ software. Moldflow™ allows components and tooling to be optimised prior to cutting steel, thus saving time and expense. Our right first time philosophy reduces time to market and keeps tooling work to a minimum.

Production flexibility:

With 15 injection presses ranging from 50 to 550 tonne closing pressure, we can offer maximum cost effectiveness on both short and long run projects.

Toolmaking, maintenance and repair:

Cox Plastics have tool maintenance and repair facilities in-house. We also provide customers with a full project design and management service for new tooling. Assembly and Finishing: Cox Plastics efficient and flexible workforce enables the company to provide cost effective assembly and finishing services, including gluing, screwing, ultrasonic welding and Tampo™ printing.

Is injection moulding right for you?

Even with the very wide range of engineering materials and fillings (glass, carbon and steel fibres) some components may be better manufactured by diecasting. Cox Plastics is part of the PC Cox Group that includes a major supplier of pressure diecastings.

Clean Room:

Cox Plastics has clean room facilities designed for the production of medical components with air filtration enabled by Hepa filters. We have 4 highly accurate electric Demag IntElect moulding machines. Of our two 50 tonne machines, one has a 14mm screw that enables the production of very small components moulded with great precision. The other machines are 100 tonne and a 150 tonne respectively, all equipment is capable of moulding commodity and engineering polymers.

IntElect machines:

Incorporating hot run controllers these machines have in built programmes enabling settings to be saved with the moulding data. Twin core pull circuits are connected to each machine and the material is fed through desiccant drying facilities (outside of the moulding area). The machines are also fitted to colour dosing units for accurate colour repeatability.

Production:

Production count is monitored both by the machine controller and by the part conveying system.
