Polystyrene is one of the best materials for injection moulding. Cycle times with polystyrene are usually short due to ease of melting, fluidity and reasonable set up times. Complex tooling can be used. The surface finish of the final product is also good, and the low mould shrinkage of polystyrene is a useful factor.
