Bulk Moulding Compound
Characterized by its doughy texture, Bulk Moulding Compound (BMC) consists of polyester resin, glass fiber and various mineral Fillers. Using BMC in the compression moulding process we can produce high-volumes of small complex parts with optimal electrical and corrosion resistant properties. The fire-retardant nature of the compound makes it ideal for use in the electrical or lighting industry.
Various liquids and powders are mixed under high shear forces.
Basic raw materials are resins, additives, catalysts, mould release agents and fillers. For coloured compounds a pigment is added to the paste.
The paste is then mixed with fibers, usually glass fibers. BMC is prepared in a mixer. After preparing a base paste it will be loaded into the mixing device. Then all other ingredients are added and homogenized. The compound is packed into bags until moulding. To avoid any material changes during storage and transport it is packaged in a styrene tight packaging.
BMC can also be injection moulded and this is a well known moulding technique with BMC. Well know products such as lighting for the automotive and mining industry are proven examples of BMC being injection moulded.
The decision on whether to injection mould or compression mould will be based on the part to be manufactured
