casting parts

Cooling of aluminum castings during use. In continuous production, the temperature of the casting mold often increases. If the temperature is too high, it not only causes the liquid metal to form a bulge, but also slows down the cooling of the casting, resulting in coarse grains and a decrease in the quality of the cast aluminum parts. Therefore, when the temperature of the casting mold is too high, cooling measures should be taken. Generally, compressed air or water is used to cool the casting mold. A cooling system is designed to maintain the thermal balance of the mold. It is strictly prohibited to use cold water to cool the mold, so as to avoid premature failure and shorten the life of the mold due to shrinkage. Of course, spraying paint appropriately during the use of the mold can not only prevent mold sticking but also have a certain cooling effect, which is beneficial for improving the life of the mold.
