What is a precision casting mold?

precision casting mold refers to precision casting, and its own mold is required to be more precise than casting mold, such as coin casting.

precision casting is a special casting. The parts obtained by this method generally do not need to be machined. Such as investment casting, pressure casting, etc.

precision casting is a casting method compared with traditional casting technology. It can obtain relatively accurate shape and high casting accuracy. The common practice is: firstly, according to the product requirements, design and manufacture a mold (with little or no allowance), and cast wax by casting to obtain the original wax mold; Repeating the procedures of coating and sanding on the wax mold, hardening the mold shell and drying; Then melt the wax pattern inside, in order to dewax and obtain the cavity; Roasting the formwork to obtain sufficient strength; Pouring required metal materials; Clear sand after shelling, so as to obtain high-precision finished products. Heat treatment and cold working are carried out according to product requirements.
