Compared to other metal casting processes, aluminum die casting produces a higher volume of parts per year than any other and it is a process in which through hydraulic or pneumatic pressure molten metal is forced into a steel mold before cooling and creating a final product.
The process benefits accommodate seemingly paradoxical needs and are wide-ranging: lightweight but stiff, consistent, ductile but strong, long-lasting, and versatile. Furthermore, for die casting the number of different alloys suitable is impressive. In the process not only are lead and tin still used, but aluminum, copper, magnesium, and zinc are all commonly used now.
A repeatable casting process is Gravity Die Casting and it is also referred to as permanent mold. For non-ferrous alloy parts, typically aluminum, zinc, and copper-base alloys and they are, it is used. The process differs from high-pressure die casting as to fill the mold with the liquid alloy there is the use of high pressure instead of gravity.
The parts of GDC are made of heavier sections than HPDC, but thinner sections than sand casting and it typically suits medium to high volumes products.
In this process there are three key stages:
With the help of a die release agent, the heated mold is coated in aluminum die casting services. A secondary function is played by the release agent especially in which after the previous part has been removed from the die.
To allow the material to fill all the extremities of the mold cavity molten alloy is poured into channels of the tool. Using steel ladles the alloy is either hand poured or using mechanical methods it is dosed. Typically, you will find a mold, down the sprue that from the lower part of the die allows the alloy to enter the mold cavity, reducing the formation of turbulence.
The die is opened, either manually or utilizing mechanical methods once the part has cooled sufficiently.
