The aluminum alloy die-casting factory makes an analysis of the reasons for the foreign matter of the die-casting particles
The existence of foreign particles will affect the quality of die-casting parts, which is a major hidden danger in die-casting production. The foreign particles will cause the phenomenon of mucous membranes, and in severe cases, the die-casting molds will be scrapped, and the burrs of aluminum alloy die-castings will increase, affecting the formation of particles. There are three reasons for this: molds, raw materials, and die-casting processes. There are four kinds of granular burrs on the surface of die castings, which are air dust adsorption, impurities in aluminum rods, defects in aluminum rods, and dust in aging furnaces. The reasons for the formation are:
1. The influence of the quality of aluminum rods. Due to high temperature casting, the casting speed is fast and the cooling strength is large.
Second, the influence of the mold. In extrusion production, the mold works under high temperature and high pressure. Under the influence of pressure and temperature, the mold is elastically deformed.
3. The influence of extrusion process. In extrusion, it is found that the selection of extrusion process parameters is also an important factor affecting granular burrs.
