sand casting technology is widely used in automobile and tractor industry. The process of sand casting resin solidified sand can produce various complex medium and small type castings with high strength and high precision in large batch production line. Hangzhou Hongcheng Pml Precision Mechanism Ltd provides sand casting service. It mainly uses aluminum process to produce aluminum castings, aluminum casting, aluminum turning sand and high strength aluminum alloy. Finally, it is used in automobile industry and machining center.

  and   sand casting is one of the main methods to obtain mechanical product blank, and it is an important basic process in the machinery industry and occupies an important position in the national economy. The current situation of China’s foundry industry is large output, annual output of about L200 million tons, foundry point up to more than 20 thousand, casting industry practitioners in more than 1 million 200 thousand people. One of the major characteristics of China’s foundry industry is the rapid development of township enterprises since reform and opening up, which has become an important force in China’s foundry industry.
    the development of casting technology in developed countries in the world now has four goals:

    1. protect the environment, reduce or even eliminate pollution

    2. improve the quality and reliability of castings and produce high quality near net shape castings;

    3. reduce the production of wood;

    4. shortening the delivery time.
