It is characterized by melting raw materials at high temperature, cooling into the mold by solution injection.
Common materials are divided into 2 categories: zinc alloy and aluminum alloy.
Zinc alloy's Parts Scope is mainly used for instrument panel brackets, toys, toy cars, lighting, decorations, boxes, automobile parts, motor parts, machine parts, etc. The advantages are good casting performance, complex shapes can be cast, the surface can be plated, powder coated, spray painted, polished and other surface treatments, low melting point, die-casting around 400 degrees, it also have good mechanical properties ,its disadvantage is high density, relatively heavy, poor thermal insulation effect, if not handled properly, the surface will easily change color, and the sealing is not good enough;
Aluminum alloyis mainly suitable for thin-wall thickness parts, heat-dissipating products, motorcycles Car shell, car oil pump, product shell and other advantages; conductive, thermal conductivity, good machinability, low density, light product good physical strength, can work normally in high and low temperature environments, good corrosion resistance, surface finish can be plated, painted, sprayed ;its disadvantage is powder coating, anodized, etc .. Its disadvantage is easier to stick to the mold, its casted parts is easy to happens bubbles, the wear resistance is poor, and the surface is more likely to have water melted line onto the surface ,its melting point of about 700 degrees etc… small problems.
