Each problem with aluminum alloy die is of course why, but can be solved by a general method.
A variety of problems often occur during the production and manufacturing of aluminum alloy die castings. If these problems can not be solved in time, it will inevitably affect the quality of aluminum alloy die-castings, making the product in poor performance.
Mold quality control. The quality of aluminum die castings is directly related to the structural design of the mold. If the internal gate should ensure that alloy has a suitable flow, flow and pressure; the design of the overflow channel should ensure that the metal can fill the cavity, thereby reducing die casting defects, such as casting Defect, loose, shrinkage, etc .
My country's die-casting industry is constantly developing new technologies, new materials, and can be seen everywhere in life. The characteristics of aluminum pressure castings have determined the level of process technology such as production, management, die casting.
The main feature of insufficient binding: The metal has been cooled before the cavity is filled, or the metal weight of the material is insufficient. The surface of the die-casting member is obvious, irregular, down-to-penetrating linear road (with penetration and non-penetrating two types), sometimes smooth, and it is possible to develop in external force. Cause: Two metal flows are diverted to each other, but there is no combination of two metal binders in both metal flows without complete fusion.
The important issue affecting the development of my country's die-casting industry is still the problem of single product, low technical content. This is because my country's current market still has a large number of small-scale die-casting enterprises, and they have less die-casting equipment, less professional and technical personnel, only By producing a single, low-cost product, but also in production management or blindly unplanned production mode.
