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;

Working Principle of Aluminum Alloy Die Castings for New Energy Automobile Die Castings
The process of mold forming, combined with die-casting machine and aluminum alloy is required. The principle of die-casting technology is to use high pressure to flow the liquid metal into the precision metal mold cavity at a high speed, and the liquid metal is cooled and solidified into castings under pressure. Cold and hot chamber die casting is two basic ways of die casting technology. In cold chamber die-casting, the metal liquid is poured into the pressing chamber by manual or automatic pouring device, and then the pressing punch moves forward to hydraulic pressure the metal into the cavity. In the hot chamber die casting process, the pressing chamber is perpendicular to the acupoint, and the metal liquid automatically flows into the pressing chamber through the feeding port on the pressing chamber. The pressure punch moves downward to push the metal liquid into the mold cavity through the gooseneck. After the metal liquid solidifies, open
