What Is Die Casting
Die casting is one of the metal casting processes, which is characterized by applying high pressure to the molten metal using the cavity of the mold. Molds are usually made of higher-strength alloys, and this process is somewhat similar to injection molding. Most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, you need to use a cold chamber machine or a hot chamber machine.
So the Die casting machines can be divided into two different types, hot chamber die casting machines and cold chamber die casting machines. The difference lies in how much force they can withstand. The typical pressure range is between 400 and 4000 tons.
Hot Chamber Die Casting
Hot chamber die casting, sometimes called gooseneck die casting, has molten liquid and semi-liquid metal in its metal pool, which fills the mold under pressure. The hot chamber die casting machines are generally used for alloys of zinc, tin, and lead. Moreover, hot chamber die casting is difficult to use for die-casting large castings, usually, this process is die-casting small castings.
Cold chamber die casting
Cold-chamber die-casting can be used when die-casting metals cannot be used in the hot-chamber die-casting process, including aluminum, magnesium, copper, and zinc alloys with high aluminum content. Cold chamber die-casting machines are divided into vertical and horizontal types. Vertical die-casting machines are usually small machines, while horizontal die-casting machines have various models.
