What materials are used to make molds for Dalian precision casting?

2022-11-15

Dalian precision casting uses fusible materials (such as wax or plastic) to make a fusible model (investment mold or model for short), which is coated with several layers of special refractory coatings. After drying and hardening to form a whole mold shell, the mold is melted off from the mold shell with steam or hot water, and then the mold shell is placed in a sand box, and the surrounding is filled with dry sand for molding, Finally, the mold is put into the baking furnace and baked at high temperature (for example, when using high-strength shell, the mold shell after demoulding can be directly baked without molding). After the mold or shell is baked, molten metal is poured into it to obtain the casting.
