Lost foam (foam type) molds are produced all year round

Characteristics of the lost foam (foam) mold process: High precision castings Lost foam casting is a new process with nearly no margin and precise molding. This process does not require mold taking, no parting surfaces, and no sand cores, so castings There are no flashes, burrs and draft angles, and the dimensional errors caused by core combination are reduced. The surface roughness of the castings can reach . to. The dimensional accuracy of the castings can reach a machining allowance of up to .
Flexible design provides sufficient freedom for casting structural design. Highly complex castings can be cast from a combination of foam molds.
There is no sand core in traditional casting, so there will be no uneven wall thickness of castings caused by inaccurate sand core size or inaccurate core position in traditional sand casting.
There is no chemical binder in the clean production molding sand, the foam plastic is harmless to the environment at low temperatures, and the recycling rate of old sand is above %.
. Reduce investment and production costs, reduce the weight of casting blanks, and have small machining allowances.
