The method of precision casting should be suitable for the production batch, such as sand casting. The factory of mass production should create conditions to adopt the advanced molding and core making methods. The production line of the old-fashioned shaker or shaker molding machine is not high enough, the labor intensity of the workers is large, the noise is large, and it is not suitable for the requirements of mass production, so it should be reformed step by step. For small castings, the production line of high-pressure molding machine without box with horizontal or vertical parting can be used. The production efficiency of solid molding is high and the floor area is small. For medium-sized castings, various production lines of high-pressure molding machine with box and air impact molding line can be selected to meet the requirements of fast and high-precision molding production line. The core making method can be selected as: high-efficiency manufacturing of cold core box, hot core box, shell core, etc Core method.
Precision casting is one of the casting methods. Compared with the traditional casting technology, it is a special method of precision casting. It can obtain relatively accurate shape and high casting precision. The common method is: first, design and manufacture the mould according to the product requirements (with very small or no allowance), cast wax by casting method, and obtain the original wax mould; repeat the coating and sanding process on the wax mould, harden the mould shell and dry it; then dissolve the internal wax mould to get the cavity for dewaxing; bake the mould shell to obtain sufficient strength and air permeability ; metal materials for pouring; sand clearing after shelling, so as to obtain high-precision finished products. According to the needs of the product or heat treatment and cold processing.
