Measures to solve the problem of porosity in castings
Porosity, also known as air hole, is one of the common defects in casting production. It is produced in the interior, surface or near surface of the casting, and it is round, long and irregular in different sizes. There are single or aggregated chips. The hole wall is smooth, white in color, and sometimes covered with a layer of oxide skin. In long-term practice, we generally call them pores, bubbles, pinholes, gas porosity and gas shrinkage pores according to their different shapes and causes.
Matters needing attention and equipment selection of new energy automobile die castings
Why do we use aluminum alloy materials for production? That's because it won't rust and can be used normally for a long time. Even so, attention should be paid to the storage. Second, avoid the contact between the die-casting parts of new energy vehicles and other chemical elements, which will cause other changes to the die-casting parts of new energy vehicles;
