Bulk moulding compoundBMC

A ready-to-mould sheet of chopped glass or carbon fibre, mineral filler and thermosetting resin, compression moulded under heat and pressure into stiff parts with good surface finish. SMC is widely used for vehicle body panels, electrical enclosures and building components.

A moulding process in which a charge of material, such as sheet moulding compound or a preheated thermoplastic blank, is placed in a heated matched metal mould and formed under press pressure. It offers short cycle times and good surface finish and is widely used for automotive panels and electrical components.

A high-volume process in which molten polymer, often short-fibre reinforced, is injected under high pressure into a closed metal mould, solidified and ejected. It provides tight tolerances and complex geometry at low unit cost once tooling costs are recovered.

Fibre drawn from molten glass, the most widely used reinforcement for polymer composites. Different formulations, such as E-glass, E-CR glass, S-glass and AR glass, balance cost, strength, electrical performance and chemical resistance. It is the standard reinforcement in GRP laminates, including liquid applied GRP flat roofing systems.
