Description

technical field

[0001] The invention relates to a method for forming and solidifying castings in the metal product replication process used in the foundry industry. Background technique

[0002] The metal product replication process used in the existing foundry industry includes water glass sand investment casting, ceramic mold casting, powder metallurgy sintering casting, etc., but the product surface of water glass sand investment casting is rough, the precision is not high, sticky sand, scabbing, Coating thickness is difficult to control; the process of ceramic casting is not easy to control, high brittleness, easy to produce large cracks, high cost, and difficult to realize mechanized automatic production; powder metallurgy sintering casting equipment has large investment and high cost; there is no casting in the existing technology The method of molding and curing. Contents of the invention

[0003] The purpose of the present invention is to provide a simple shape, l...
