Process flow of aluminum alloy die casting parts

Aluminum materials and aluminum alloy have good fluidity and plasticity, so they can make a variety of complex shapes and difficult die-casting parts, castings with aluminum alloy and metal aluminum casting have high precision and surface finish, which greatly reduces the amount of mechanical processing of castings, greatly reduces labor intensity, and saves electricity and metal materials. Its high internal quality and external quality, aluminum die casting parts are widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, and other industries, become the new favorite of aluminum die casting manufacturers.

Solution treatment is to heat the die casting to a high temperature, maintain a long time at this temperature, and then quickly cool, so that the product reaches the maximum dissolution, which can improve the strength and plasticity of the casting, and add the corrosion resistance of the alloy casting. So the role of solution treatment is mainly related to which aspects

Solution treatment is to heat the die casting to a high temperature, maintain a long time at this temperature, and then quickly cool, so that the product reaches the maximum dissolution, which can improve the strength and plasticity of the casting, and add the corrosion resistance of the alloy casting. So the role of solution treatment is mainly related to which aspects?

1. The time of insulation is determined according to the dissolution rate, which is also related to the type of alloy composition arrangement casting method and the shape and thickness of the casting.

2. The faster the cooling speed, the higher the mechanical properties of the casting, and the possibility of casting deformation will be relatively large. So many castings are cooled in a hot medium.

3. The higher the temperature of solution treatment, the faster the dissolution rate will be, the better the effect.

The role of solid solution of aluminum alloy die-casting is mainly because of the above three points, in the process of manufacturing products it is easy to produce thin rough edges, which has an impact on the appearance and quality of products, Ruimei mechanical frozen burring machine can remove rough edges without damaging the surface of the product, the volume of relatively small products can play thousands of six or seven minutes at a time, and the production efficiency is high and the factory costs are saved.
