SMC is a high strength glass reinforced thermoset moulding material which is normally compression moulded. It combines long glass fibre and unsaturated Polyester/ Phenolic/ Vinyl and Acrylic modified resins to produce a high strength moulding compound. These materials are usually formulated to meet performance requirements of the part to be moulded. CME manufactures these materials at our Bayswater plant in Victoria.
SMC is ideal for large structural components due to its high strength-to-weight ratio. SMC offers additional benefits in part design allowing localised rib reinforcement and bosses for fastening attachments and sub-assemblies. Significant tooling investment and overall component cost savings result from part consolidation. With the same coefficient of thermal expansion as Steel and excellent corrosion resistance, SMC is an ideal alternative to Steel and can be used in the same fluctuating temperature environments. The main benefit however is a typical 25% weight reduction achieved at similar strength to Steel.
The heat stability, mechanical and electrical properties of SMC are key attributes to its success in a number of industries including the automotive sector where it is commonly used in painted body panels, lightweight structural panels such as bumpers, valve covers, and engine shields. SMC is also extensively used in the production of electrical enclosures, lighting, solar, shower bases, walls, and sinks.
