Zinc

Due to its good flow characteristics, zinc die castings can be made to close tolerances with thinner walls than aluminum.  Zinc die casting is often referred to as the "hot chamber" process as the pressure chamber is connected to the die cavity and is immersed permanently in the molten metal.  This process allows for a fast fill, fast cooling and ejection.  This translates to a short cycle time, which equals lower unit prices. Die life typically exceeds one million shots. Zinc die castings are often plated to enhance corrosion resistance.
