Development Prospect of Precision Steel Investment Casting

Precision Steel Investment Casting refers to the use of fusible materials made of fusible model in some special refractory coating layer on the coating, after drying and hardening to form a whole shell, then steam or hot water from the shell in the melt model, then put the shell into the sand box, dry sand filling in the other around, finally casting into the baking furnace after calcination, cast or shell after roasting, the pouring of molten metal and casting. 

The products obtained by Precision Steel Casting are sophisticated and complex, they are close to the final shape of parts. They can be directly processed. This is an advanced technology, is an excellent technology in foundry industry. The size and surface quality of the investment castings are higher than other casting methods. 

At present, the Investment Casting technology in the world is developing rapidly and widely applied, the future development prospect will be broad.
