SMC is a moulding compound, often used for larger parts, where higher mechanical strength is required. Glass reinforcement represents between 20% and 60% with glass length superior to the DMC.
SMC is a mixture of polyester resin, inert fillers, fibre reinforcement, catalysts, pigments, release agent and thickeners.
SMC manufacturing is a continuous in-line process using styrene tight film in sheet form. The resin paste prepared is spread onto the bottom film, and chopped glass fibres are randomly deposited onto the paste. The top film is introduced and the sandwich is rolled into a pre-determined thickness. The sheet moulding compounds are formulated and packaged on rolls or in cardboard boxes (zig-zag).
Sheet Molding Compound can be molded into complex shapes. Superior mechanical properties and surface appearance plus excellent electrical insulation, make this SMC material ideal for Class A automotive body panels, high-strength electrical parts, electrical industrial boxes and various structural components.
DMC is a thermoset resin blend of various inert fillers, fibres reinforcement, catalysts, stabilizers and pigments, used for injection moulding most of the time.
DMC material is highly filled and reinforced with short fibres: glass reinforcement represents between 10% and 30%, with glass length between 6mm and 12mm.
Depending on the end-use application, dough moulding compounds are formulated to achieve close dimensional control, flame and track resistance, electrical insulation, corrosion and stain resistance, superior mechanical properties, low shrink and colour stability. Its excellent flow characteristics, dielectric properties and flame resistance, make the DMC material adequate to a wide variety of applications, requiring precision in detail and dimensions as well as high performance. The DMC material is available in a broad type of colours, and can tolerate powder-coat
