  • What surface treatment is required for aluminum alloy die casting?
    1. Aluminum phosphating
    The effects of accelerant, fluoride, Mn2+, Ni2+, Zn2+, PO4 and Fe2+on the phosphating process of aluminum were studied in detail by means of SEM, XRD, potential time curve and film weight change.
  • Pay attention to the following points when producing and using aluminum alloy die-casting die?
    1. When aluminum alloy liquid metal enters the mold cavity under high pressure and high speed, it will produce intense friction and impact on the surface of the formed parts of the mold, causing erosion and wear on the surface of the mold.
  • What are the performance requirements of aluminum alloy die casting die steel? It is mainly used for parts of some instruments. According to the service conditions and common failure forms of aluminum alloy die casting die, the main performance requirements for steel used for aluminum alloy die casting die are as follows:
  • Aluminum alloy die-casting is a process of metal smelting processing. It is a casting method that the molten alloy liquid is filled into the cavity of the steel mold at a high speed under the action of high pressure, and the alloy liquid is solidified under pressure to form castings. It is somewhat similar to Dalian die-casting, which is different from other casting methods in its main characteristics of high pressure and high speed.
  • Aluminum alloy die castings refer to aluminum or aluminum alloy equipment and devices obtained by casting. Generally, aluminum or aluminum alloy heated to liquid is poured into the mold cavity through sand mold or metal mold to obtain aluminum parts or aluminum alloy parts of many shapes and sizes, which are generally called aluminum alloy die castings.
  • Dalian aluminum alloy die casting is mainly used in electronics, automobiles, motors, home appliances and some communication industries. Some aluminum alloy products with high performance, high precision and high toughness are also used in industries with high requirements such as large aircraft and ships.
