Metal Casting Services

Whether it is hot chamber die casting or cold chamber die casting, the standard process involves injecting molten metal into the mold under high pressure. The following are steps in the complex die casting process:
Step 1: Clamping. Prior to this, the mold needs to be cleaned to remove any contaminants and lubricated for better injection and removal of cured product. After this, the mold is clamped and closed with high pressure.
Step 2: Injection. The metal to be injected is melted and poured into the firing chamber. The metal is then injected into the mold under high pressure generated by the hydraulic system.
Step 3: Cooling. The solidified material will have a shape similar to the mold design.
Step 4: Ejection. After loosening the mold, the ejector mechanism pushes the solid casting out of the mold. Proper solidification is ensured before ejecting the final product.
Step 5: Decorating. It involves removing excess metal from the finished gate and runners. Trimming can be done using a trimming die, saw, or other procedures.

Instead of being made primarily of iron, die castings are usually produced from materials such as zinc, copper, aluminum, and magnesium, which makes the parts corrosion-resistant and less prone to rusting. However, if the parts are not stored in a proper manner for a long period of time, they may rust.
