Investment casting is a kind of casting, which use silica sol to make the precision stainless steel, carbon steel, and brass & bronze parts. There are nine technics process steps for investment casting.
Silica sol shell injected. Using mold injection make to make the silica sol housing. The mold is made based on the part shape. Normally, manual single injection mold is requested for small quantity, and automatic multiple injection mold is requested for large quantity.
Air drying. Hang the shell with the sand on the rack. The rack will be in the constant temperature and constant humidity room. The shell will be dried by air in the room.
Silica sol shell removing. Melting the silica sol shell in the stove. The sand housing will be hollow without silica sol shell.
Investment casting. Melting the stainless steel ingot, carbon steel ingot, brass ingot, or bronze ingot. Pouring the melting metal water in the sand housing. Put the housing in the ground to cooling.
