What's The Die Casting Mold For Zinc Alloy ?

Die Cast Zinc Alloy Mold is also commonly known as Dies. These molds are used for the mass-production of zinc alloy parts. Mold making used to be a difficult task before. Thanks to the CNC Machining technology mold making is now faster and more efficient than ever.

Zinc-alloy Die casting Mould requires a material that has higher strength and melting temperature than Zinc. Otherwise, the die will be damaged during the casting process. Usually, steel molds are used for Zinc die casting.

High-quality steel is quite costly and hard to machine. So, the die tooling cost is relatively high. Even though the high tooling cost,Zinc-alloy die casting toolings provides the best economy and quality for large volume production.

Components of Die Casting Mold

A Die Cast Mold consists of multiple parts with each serving a specific purpose. The main components in a die casting mold are listed below.

  • Cover Die                                
  • Ejector Die
  • Ejector Pin
  • Runner
  • Sprue
  • Cavity Insert
  • Ejector Plate
  • Support Plate etc.

Advantages of Zinc-alloy Die Cast Mold

Zinc-alloy die cast mould has made the production of Zinc-alloy parts a lot easier. Some of the benefits of die casting molds are explained below:
  • A single mold can produce thousands of parts
  • Can produce parts with very tight tolerances
  • Can withstand high temperatures
  • Can withstand very high pressure
  • Significantly reduces production cost for large volume production
  • Can manufacture multiple aluminum parts at one go
  • Increased rate of cooling and solidification allows faster production
  • For these multiple advantages, aluminum die-cast mold is being used for boosting aluminum die casting capacity.
