Thermoset Moulding & Thermoplastic Injection Moulding Birmingham
Coleshill Plastics offer both Thermoset Injection moulding and Thermoplastic injection moulding. Thermoset moulding which is also known as DST (direct screw transfer) moulding.
At Coleshill Plastics we have a dedicated range of thermoset injection machines that give us the capability to produce products /components with shot weights of a few grams up to over 3.4 kilos, in materials which include: Melamine, Urea, Phenolic (Bakelite), BMC (Bulk Moulding Compound) and SMC (Sheet Moulding Compound). These materials come in various forms including: Granulated Powder, Pellets, Fibrous Dough, Sheet and Strip. Some of these require specialised feeding equipment on the injection unit.
We also have one of a very limited number of machines in the UK capable of injection moulding SMC (Sheet Moulding Compound).
The material is fed, plasticised and metered in the machines barrel and screw and then injected under high pressure into a closed heated mould and held under pressure until cured sufficiently to be ejected. In addition the machines are equipped with vacuum extraction to enable fast injection speeds required to achieve cosmetic surface finishes, without the associated gas trapping. Mechanical and hydraulic ejection, core pulling and integral gate cropping making the machinery extremely versatile.
Thermoplastic Injection Moulding Coventry
Whilst this is relatively new addition to our skills base we have equipment fitted with multi-zone heating as well as cooling to accommodate the high specification engineering thermoplastics which include Peek, Ultem, Polycarbonate, and a host of more general materials such as Nylons, Acetal, ABS, Polypropylene.
The thermoplastic injection moulding process uses pellets of material that are fed, plasticised and metered in the machines heated barrel and screw. The molten polymer is then injected into a closed metal mould at high pressure and held under pressure until cooled sufficiently to allow ejection.
Thermoplastic injection moulding is used in the manufacture of an extremely wide range of products from everyday packaging and bottle caps to high specification aerospace components.
Coleshill Plastics offer a wide range of additional moulding services such as Thermoset Moulding and Compression Moulding
