Material: GF (cut glass fiber), UP (unsaturated resin), MD (filler calcium carbonate) and various additives
Color & Logo: Blue, red, white, black
BMC material is an abbreviation for Bulk molding compounds, that is, pellet molding plastics. Its main raw materials are GF (cut glass fiber), UP (unsaturated resin), MD (filler calcium carbonate) and various additives, which are fully mixed into a pellet prepreg. BMC have excellent electrical properties, mechanical properties, heat resistance, chemical corrosion resistance, and adapt to a variety of molding processes, can meet the performance requirements of various products.
Product Advantages
Flexible Design: BMC can be molded or injection-molded in a single step, reducing post-processing. We excel in producing everything from large flat panels to complex precision components. During molding, we can design grooves/through-holes to eliminate subsequent machining, integrate metal inserts to save assembly steps, accommodate any intricate structural design to enhance production efficiency, and simplify part structures with integrated designs.
Customized Performance: As a composite material, BMC offers diverse compositions. Adjusting the types and proportions of its components alters both material properties and molding processes while delivering exceptional characteristics. Huayuan carefully selects raw materials tailored to your requirements to meet varying processing and performance needs.
High Structural Precision: BMC achieves zero shrinkage during and after molding, with an extremely low coefficient of thermal expansion. It requires no shaping fixtures or additional machining, perfectly replicating the dimensions of the mold cavity and core. Its excellent dimensional stability ensures a flawless fit.
