Casting Process

Lost Foam Casting

Lost foam casting is a new type of casting method that bonds and combines the paraffin or foam model that has the similar size and shape with the casting to form cluster model, after coating it with fireproof paint and drying it, bury it in the dry silica sand for vibration modeling, pour it under negative pressure to gasify the model, and the liquid metal will take up the model and form casting after solidification and cooling. Our company is one of the professional lost foam casting manufacturers with strong technical power, and the castings cast with this casting technology such as motorcycle accessories, auto spare parts, gear, impeller and electrical machine take a leading role in the lost foam casting industry.
