Lost foam casting is suitable for group casting. Dry sand buried mold is easy to remove sand. In some castings, waste heat treatment can be carried out according to the purpose. Lost foam casting is not only suitable for small and medium-sized parts, but also for large castings, such as machine tools, large diameter pipe fittings, large cold stamping mold parts, and large mining equipment accessories. Due to its short production cycle, low cost, and short production cycle, it has been particularly praised. Lost foam casting is a new process of precision casting with almost no allowance. It does not require mold removal, no parting surface, and no sand core. The casting does not produce flash, burrs, and draft angles, reducing dimensional errors caused by core combinations. It provides sufficient degrees of freedom for the structural design of lost foam casting. The combination of foam plastic blocks can produce highly complex castings. Therefore, in traditional sand casting, due to inaccurate sand core size or inaccurate position of the lower sand core, the wall thickness of the casting will not be uneven. There is no chemical adhesive in the molding sand. The foamed plastic is environmentally friendly at low temperature, and the recovery rate of waste sand is more than 95%. Reduce the weight of the casting billet and reduce machining allowance.
