How to solve the defect problem of aluminum alloy die casting?

Aluminum alloy die-castingParts are widely used in many industries and fields, such as electronic products, automobiles, and daily necessities. However, some common defects of aluminum alloy die-casting and their solutions are described below.

1. Impurity problems

Impurity problems of aluminum alloy die-casting are mainly composed of compounds containing aluminum, silicon, and a large amount of iron, manganese, chromium, etc. at a certain temperature, And some oxides can be solved by strictly controlling the composition of aluminum ingots, regularly cleaning the furnace bed and regularly slagging the smelting furnace

2. Air hole problem

Air hole refers to the holes of different sizes on the inside or surface of the die casting, which will lead to insufficient hardness of the die casting and affect the appearance of the surface. The air hole can be treated and the process can be adjusted with appropriate refining agent, Properly reduce the low speed and confirm whether the release agent is sprayed too much to deal with the air hole problem

3. Crack problem

The crack refers to that the matrix of aluminum alloy die castings is damaged, generating long and thin cracks, which are linear or other lines, and tend to extend under external forces. It can be solved by correctly controlling the alloy composition, increasing the cooling water circuit, changing the structure of aluminum alloy die castings, and changing or increasing the ejection position
