What is Zinc die casting

Zinc die casting is a process in which molten zinc is injected under high pressure into a die (a tool with a specific shape) to produce zinc alloy parts. The process is known for producing zinc die casting parts with good dimensional accuracy and surface finish. It is commonly used to produce small, complex-shaped zinc alloy die casting parts, such as those found in the electronics, automotive, furniture, and hardware industries.

The zinc die casting process is fast and efficient, and it allows for the production of a large volume of zinc alloy die casting parts in a short period of time. The main advantage of zinc die casting is that it allows for the production of parts with a high level of detail and accuracy.zinc-die-casting

There two kinds of die casting processes available for zinc high pressure die casting. Commonly we cast small zinc die cast products by hot chamber die casting machine, and larger parts by cold chamber die casting machines. Thus before we start zinc die casting design, we will confirmed with customers which kinds of machine he prefers. Except of this issue, the design of zinc die casting is quite the same as that of aluminum die casting.

Zinc alloy die casting mold

A zinc alloy die casting mold is a tool that is used in the zinc die casting process to shape molten zinc into a specific shape. The mold consists of two halves that are made from hardened steel or another strong and durable material. One half of the mold is stationary which we called cavity side, while the other half is movable which we called core side. The two halves of the mold fit together precisely and are held together with a clamping force during the casting process.

Zinc alloy die casting molds can be designed and manufactured to produce a wide range of parts with different shapes and sizes. They can be used to produce small, intricate parts as well as larger, more complex parts. The design of the mold is an important factor in the quality and accuracy of the finished parts.
