Lost foam process is to use foam (EPS, STMMA or EPMMA) polymer materials to produce casting parts structure, which is exactly the same size of mould. After dip-coating refractory coating (reinforcement, bright and clean, well ventilated effect), and drying, foam is buried in the dry quartz sand. Under negative pressure condition, pouring into the molten metal, and polymer material model will be heat gasification, and then making the liquid metal cooling solidification. The metal part is the casting.
We produce lost foam castings, including motor housing, cylinder body, gearbox, high chromium cast iron - wear-resistant parts, valve body, pipe fitting, pump housing, agricultural machinery products, machine tool parts and so on.
