Zinc Die Casting Tooling. Also known as zinc die casting dies or zinc die casting molds, zinc die casting tooling is essential equipment in the zinc die casting process. It comes in a mixture of shapes, sizes and design but it only has one purpose. Zinc die casting tooling permits the molten zinc to be shaped by applying pressure and heat.
Zinc die casting tooling consists of solid alloy steels. These alloy steel are typically separated into two sections and are used for the casting of the molten zinc alloy. The first part is the cover half. This half is more often than not the one that is fixed in a cast. The other one is the ejector die half. This other half is used for the removal of the hardened zinc alloy. It includes pins to force the two halves together until the zinc solidifies.
Over the years, engineers have produced zinc die casting tooling which consists not only of two sections as mold. Modern zinc die casting tooling may now hold slides and cores. This is because many zinc parts now need certain details such as holes and threads. With slides and cores, such requirement can be applied.
Aside from the pins, hydraulic pressure is applied to the halves to help with the solidification process. Pressure is applied for about 2-15 seconds depending on the size of the zinc die casting tooling. Lubrication is applied to make the disconnection of the zinc alloy from the casting easier. Added operations are executed in order to trim and polish the product.
