What is Lost Foam Casting?

Lost foam casting is suitable for group casting. It is easy to remove sand from dry sand buried molds. In some castings, according to the use of the remaining heat treatment.
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, large mining equipment parts, etc., due to its short production cycle, low cost, short production cycle, especially well received.

Lost foam casting is a new process of nearly no allowance, precision casting, no need to take the mold, no parting surface, no sand core, the casting does not produce flying edges, burrs and pulling angle, reducing the size error caused by the combination of the core. It provides enough freedom for the structural design of vanishing mold casting. Highly complex castings can be produced through the combination of foam blocks.
Therefore, in conventional sand casting, the wall thickness of castings will not be uneven due to inaccurate core dimensions or inaccurate location of the lower core. The foam is environmentally friendly at low temperatures and has a waste sand recovery rate of over 95%. Reduce the weight of the casting blank and reduce the machining allowance.
