Specialize in Compression molds
SMC is a flat sheet-like compound, produced on a continuous moving belt process. The SMC composites are made from chopped multi end rowing strand sandwiched between two layers of film, onto the resin paste (resin, shrink compensation, fillers, additives and curing agent) has already been applied. The prepreg passes through a compaction system that ensures complete strand impregnation and makes a sheet wound into rolls. These are stored for pre maturing before moulding to allow the prepreg to thicken into a mouldable viscosity.
A typical formulation for a SMC is given below.
|Raw material||Parts by weight|
|Unsaturated Polyester resin||60|
|Low profile additive||40|
|Magnesium oxide paste (35% MgO)||2|
|Glass fibres||25%on total formulation|
SMC is a moulding compound made on the basis of glass-fibre reinforced unsaturated polyester resin. The use of Sheet Moulding Compound (SMC) is a very important production process for high volume production.
Bayer AG in Germany was the first to develop a process to produce thermoset polyester sheet molding compound (SMC) during the early 1960s, while Owens Corning Fiberglas was instrumental in bringing the process to the U.S. SMC combined resin, filler, and chopped glass in a doughy, easily handled sheet. The emergence of SMC resulted in the first mass-production process for composites, which offered a wide range of advantages over open-mold hand lay-up and spray-up composite methods.
