SMC/BMC mold properties introduction

SMC and BMC are ideal composites for the manufacture of large, lightweight and complex parts that combine structural performance with surface finish quality, and are therefore increasingly used in a wide range of end-use markets.

From coffee makers and cookware at home, to electrical cabinets on the street and body panels on cars, SMC and BMC molds have been part of our lives for decades. In these applications, and in countless others, SMC molds and BMC molds have been a competitive, sustainable alternative to metals and thermoplastics.

BMC is the abbreviation of Bulk Molding Compounds, that is, Bulk Molding Compounds.

BMC is a thermosetting plastic mixed with various inert fillers, fiber-reinforced materials, catalysts, stabilizers and pigments to form an adhesive "putty-like" composite material for compression or injection molding. Granular, log or long strips to facilitate subsequent processing and shaping.

BMC has many unique properties, such as high hardness, light weight, corrosion resistance, UV resistance, good insulation, and excellent thermal properties, which make BMC more satisfactory than thermoplastics. At the same time, since many components can be molded at the same time as these parts, no post-processing is required, which is more economical from a production standpoint.

At present, BMC molds have been used in automotive, energy, electrical appliances, catering services, household appliances, optical instrument components, industrial and building supplies and other areas.

SMC is sheet molding compound.

The main raw materials of SMC are composed of GF (special yarn), UP (unsaturated resin), low shrinkage additive, MD (filler) and various auxiliaries.

SMC molding has the advantages of excellent corrosion resistance, soft quality, easy engineering design and flexibility, and its mechanical properties can be comparable to some metal materials.

At the same time, the size of SMC products is not easy to deform, and has excellent heat resistance; it can maintain its performance well in cold and hot environments, and is suitable for outdoor anti-ultraviolet and waterproof functions. Automotive, industrial, medical, sanitary and other areas are also relatively wide.

With the gradual popularization of SMC and BMC molds, people's lives are also more convenient. More and more customers find the merchants among them. MDC is a professional supplier of SMC molding and BMC molding, which can meet your order needs. Please contact us!
