Development prospect of precision casting

Investment casting refers to the use of fusible materials to make a fusible model, which is coated with several layers of special refractory paint, after drying and hardening to form an integral mold shell, then steam or hot water is used to remove the mold shell Melt the model, then put the mold shell in the sand box, fill it with dry sand molding, and finally put the mold into a roaster for high temperature roasting. After the mold or shell is roasted, pour molten metal into it Get the casting.
