Sheet Moulding Compound (SMC) is a thermoset composite material and used for large spoiler sets and other exterior skin components for trucks. Because of its high strength, SMC is used as a reliable construction material. In combination with its high design freedom, SMC is an excellent alternative for metal parts. To simplify painting and improve surface quality In-Mould Coating (IMC) is often used. In addition, voestalpine Plastics Solutions uses vacuum technologies to improve surface quality even to a higher level.
