Casting selection principle for precision castings
<a href="https://casting-china.org/stainless-steel-castings.html">Stainless steel casting</a> is to use a suitable investment material to make the investment mold. Repeat the coating of the refractory coating, refractory sand, hardening and drying on the investment mold, and then melt the internal investment material; then, the strength is sufficient by roasting. A shell type without residual investment material for casting molten metal to obtain a high-precision casting. The lost wax casting process is adopted, the investment material is paraffin and stearic acid, the wax mold making and shell making process adopts an automatic assembly line, and the coating uses water glass as a binder.
