Mineral Casting

Mineral casting, also known as resin concrete, is a kind of new-type composite material products composed of inorganic mineral materials and high-performance thermosetting resin system.

The combination of both inorganic and organic materials provides this material with outstanding damping performance, high dimensional precision, low heat conductivity, relatively high specific heat capacity, good corrosion resistance and low water absorption. In addition, by taking advantage of the molding of resin composite materials, mineral casting can be employed to design complicated embedded parts, with small internal stress for curing under room temperature, and short molding cycle.
