casting is a process of metal smelting, usually using metal gravity in die casting, aluminum alloy die-casting is the most common process of mechanical industry. Hongcheng precision machinery is Hangzhou CNC machining center processing, providing aluminum alloy sand, gravity casting, aluminum alloy die-casting, aluminum sand casting technology support.

    die casting aluminum alloys are widely used in the world, with over 3000 models. Aluminum alloy die-casting has the following 7 basic requirements: 1. better flow performance, 2. shrinkage, low cracking tendency, 3. isothermal solidification ratio, such words can produce dense surface casting muscle, avoid shrinkage damage, 4. have certain high temperature strength 5. at normal temperature, enough strength to produce thin section 6. is not easy and die. Chemical or physical reaction, otherwise the mucous membrane will affect mass production 7. good processing properties and corrosion resistance
