BMC is used in the electrical industry
Bulk molding compound (BMC) is a thermosetting composition based on polyester and can be injection molded or molded. Traditionally, bulk molding compounds have been used to mold components that require superior electrical, building, corrosion, or heat resistance. For a long time it has been mainly limited to the production of invisible or "run" parts of electrical appliances such as brush holders, armature bushings and motor mounts. Bulk molding compounds are often used to produce electrical (circuit breaker) components and automotive (bonnet and headlight) components.
The bulk molding compound is a moldable product, so a complex structure can be used, components can be combined, and design freedom is large. By using traditional raw materials and new chemical additives, higher surface quality can be achieved. The improved mold design, together with excellent molding equipment, makes the bulk molding compound fully capable of meeting the aesthetic requirements of end use.
Today, home appliance manufacturers use bulk molding compounds for ventilated door trims, refrigerator handles, control panels, and door exterior components. The main applications for small household appliances are the side panels and door handles of the toasters, the soleplate of the soleplate of the soleplate, the bottom of the frying pan, and the cover. Heating ventilation and air conditioning are used for humidifier seats and coil drip trays.
