the lightweight requirements of parts and components make the cast aluminum alloy get a great development, but the increasingly strict environmental protection standards also make the casting enterprises face a severe test. Facing the increasingly serious energy and environmental crisis, lightweight has become an important direction for the development of parts industry. In recent years, aluminum castings have developed rapidly.
    Hongcheng Precision Machinery Co., Ltd. is an aluminum casting manufacturer in Hangzhou, specializing in casting aluminum alloy and making aluminum foundry technology. Green casting is the inevitable direction of the development of the foundry enterprises. Therefore, in order to survive and maintain a high competitiveness, the foundry enterprises must be green from many aspects, multi angles and all directions.

    in order to get pure aluminum liquid, aluminum foundry should “ prevent ” that is to say, fully prepare before smelting. The furnace charge is removed, the oil is removed, the heat is preheated, the smelting tools are cleaned, the paint is brushed, and the drying is preheated; the material and dosage are reasonably selected. If properly prevented, the subsequent refining process can be simplified so as to reduce environmental pollution caused by refining.
