BMC - bulk molding compound is a glass-fiber reinforced thermoset polymer material and is used in compression moulding, as well as in injection and transfer moulding. This material made up of a polymer resin, various inert fillers, fiber reinforcement, catalysts, stabilizers, and pigments that form a viscous. It is filled and reinforced with short fibers.
BMC is available in bulk bags as well as slug form. The mixing operation can be done in many ways. There are three methods for combining glass with the paste: a continuous screw mixer, a sigma blade mixer and a plough blade mixer. The process chosen is dependent upon specific product properties, form and volume.
Depending on the end-use application, BMC are formulated to achieve tight dimensional control, flame resistance, high dielectric strength, corrosion and stain resistance and color stability. Its excellent flow characteristics make BMC suited to a wide variety of applications, and is available in a wide variety of colors.
What is BMC moulding? BMC moulding process is performed by compression at a temperature and pressure of 130 -170oC (pressure 20-100 bar) or in an injection molding machine (mold temperature of 145 -175oC, pressure 80-160 bar). In the whole process, the temperature, and pressure affect the quality and accuracy of BMC products.
BMC compressing molding is used to produce complex components such as electrical equipment, car components, housings for electrical appliances and tools, in large industrial volumes. Please note that you need to pay attention to mould steel, and life cycle. The BMC mould catalog as follows:
