Zinc Die Casting

Custom Zinc Die Casting

Zinc alloys are composed of multiple metals in specific ratios. For instance, a typical workpiece would boast 7% to 10% tin, 4% to 7% copper, and 86% zinc. 

A versatile and economical material that is easy to cast, it is widely used to custom parts and components for different industrial applications – such as electronic devices, fuel systems, and more. Zinc also responds exceptionally well to the molding process. 

Depending on the type of metal being cast, zinc die casting employs either the conventional machine or multi slide machine.

    Zinc Die Casting Process

    The hot chamber technique is typically used during the zinc die casting process, allowing for superior control over the molten metal flow. During this process, the furnace is first attached to the die casting machine using a metal feed system (also known as a gooseneck). Next, the injection mechanism is immersed into a molten metal bath within the furnace. Once the process begins, the plunger is pushed downwards, forcing the metal within the chamber to the die cavity. 

    Due to zinc’s mechanical properties, zinc die casting processes are much faster than other materials like aluminium. The end result is a precise component with high-quality finishing.

    Frequently Asked Questions About Zinc Die Casting

    Why is Zinc Widely Used in Die Casting?

    Zinc alloy is widely used due to the many benefits it offers. These include:

    • Fast production rates
    • Economical due to low raw material and fabrication costs
    • Superior casting fluidity and strength 
    • Dimensionally stable
    • High aesthetic quality
    • Corrosion resistance 
    • Immense design flexibility
    • Castable to tight tolerances

    What are the Applications of Zinc Die Casting?

    Zinc die casting applications are widespread – they are used in our everyday applications such as furniture components and mechanical hardware. Numerous industries spanning automotive, electronics, appliance manufacturers, mechanical designs, and more also rely on zinc die casting to obtain specific components. 

    How is Zinc Better than Other Materials?

    Each alloy boasts unique physical and mechanical properties, and are suitable for varying design application. Hence, it is nearly impossible to define its superiority. If you are looking for a cost-effective approach to high volume production, zinc can be an ideal choice. Further, zinc alloy is more precise and detailed – so if you are looking to create smaller draft angles or thinner wall sections, zinc makes a great choice too.
