The use of high-quality low carbon steel and raw iron with the same material as the smelting raw materials, according to the composition requirements of the automatic feeding, the use of the United States should da electric furnace for full melting, after the automatic inoculation treatment, the use of automatic casting machine for casting, the chemical composition will be tested by the spectrometer before casting, effectively ensure the uniformity of the material and the consistency of casting quality.

In the core making process, a fully automatic core making production line is adopted. After core formation, a robot is used to grip the whole immersed sand core, and then the drying process is carried out to ensure the consistency of the quality of the sand core. The sand core that has been tested and qualified is automatically transported to the HWS automatic production line, and the automatic pouring machine is used to achieve continuous and stable production.

The cast blank is desanded and polished, then heat treated to eliminate the residual stress, and then the comprehensive appearance, inner cavity, hardness and tensile strength are tested. After passing the inspection, the subsequent processing can be carried out.
