BMC mold in the electrical industry
Electrical components require high heat resistance, good surface quality, and aesthetics, so traditionally metal, base material plus coatings, or thermoplastics have been chosen for manufacturing. Bulk molding compound (BMC) can meet the essential performance of electrical production. Its durability in harsh environments has been recognized as a material that can "tolerate heat," and the electrical industry is no stranger to it. Decorative parts made with it are very popular. With the help of modern formulations, mold design and process technology, it is possible to design and mass produce glossy, dark-colored parts. Block molding compounds offer excellent price/performance ratio compared to thermoplastics and coated substrates
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.
The temperature of the mold directly affects the molding quality and production efficiency of the product, so the mold needs to add a heating system to achieve the desired temperature.
The heating system is divided into electric heating, steam heating and oil heating. Electric heating is the most commonly used heating method. Its advantages are simple and compact equipment, low investment, easy installation, maintenance and use, easy temperature adjustment and easy automatic control; steam heating, fast heating, relatively uniform temperature, but not easy to control, cost Relatively high electric heating; oil heating, uniform temperature and stability, fast heating, but the pollution of the working environment.
