BMC block-molded plastic material has excellent electrical performance, mechanical performance, heat resistance, and chemical corrosion resistance. It is suitable for various molding processes and can meet the performance requirements of various products. Therefore, it is increasingly popular with users.

BMC material is a thermosetting plastic that mixes various inert fillers, fiber reinforced materials, catalysts, stabilizers, and pigments to form a glue-like composite material for compression or injection molding. Bulk molding material (BMC molding material) is highly filled and reinforced by short fibers, with glass fiber reinforced materials accounting for 10% to 30%, usually between 1/32 inch and 1/2 inch (12.5mm) in length.

Applications of BMC material in the electrical equipment manufacturing industry

Electrical components usually require high temperature resistance, good process performance, and beautiful appearance. Therefore, metal materials, base steel plates, and plated or thermosetting plastics have been used for production and manufacturing. BMC material can meet the basic characteristics of electrical equipment manufacturing, and its high temperature resistance can be well used in extreme natural environments.

Furthermore, relying on formulations, stamping molds, and processing technologies, it is possible to design and produce bright and dull parts in large quantities. Compared with thermosetting plastics and plated base steel plates, integral molding materials have excellent cost characteristics. The raw materials meet the special color and temperature requirements of the electrical manufacturing industry, eliminating scratches caused by secondary painting.

In addition, the application of BMC material further improves productivity and operational capability. Plastics formed by fragments have traditionally been used for grinding parts requiring high quality electrical equipment, engineering construction, corrosion resistance, or temperature resistance. Electrical equipment components that are invisible or movable, such as electrical brushes, waterproof shells for synchronous motors, sound card racks, etc., have always been manufactured.

BMC materials are also commonly used in the production of electrical equipment and automotive parts

During the production process, complex structures can be selected, parts can be assembled, and design schemes can be selected. By using traditional raw materials and new organic chemical anti-corrosion agents, higher process performance can be obtained. With the improvement of stamping molds and high-quality molding equipment, small molded plastics can fully consider the beautiful appearance requirements of the final application.

It should be noted that for some commodities used at high temperatures, extra caution should be taken when selecting raw materials. Therefore, long-term high temperature bearing capacity is an important indicator value of BMC material. The selection of raw materials is relatively complicated in terms of artistic aesthetics, such as color consistency, color fastness, etc. Heating, gloss and resistance to pollution are important factors.

Depending on the application field, the prepared composite material can precisely control the size, has good flame retardancy and resistance to electric marks, high dielectric strength, corrosion resistance, and resistance to contamination, excellent mechanical performance, low shrinkage rate and stable color. BMC material has excellent flowability, insulation and flame retardancy, and is very suitable for various applications with precise details and dimensions. The material has 75 colors and can withstand powder coating or water-based coatings.
