Top 5 Benefits of Zinc Die Casting

  • Die casting refers to the method of forcing molten metal under high pressure into the mould cavity. This method is a widely accepted manufacturing process that is used for accurate dimensions, sharp definition and desirable textured or smooth surface. Zinc die casting alloys are considered as a versatile engineering material as the alloys have a good combination of toughness, durability, strength and hardness.


    In the process of die casting, usually non-ferrous metals like copper, zinc, aluminium and magnesium are used. There are many reputed Zinc die casting manufacturers that offer zinc die casting products with several useful features like hardiness, firmness and financial affordability.  Apart from all these features zinc metal is widely used in the die casting procedure because of its excellent thermal and electrical conductivity. However, some of the important benefits of using zinc die casting alloys are discussed below; (Information Credit –


    1. Durability:

    Zinc die casting products are widely used in several engineering and non-engineering industries because of its high tolerance and firmness compared to the other metals like copper, aluminium or magnesium. Zinc is marked for its high strength and durability, elongation for high quality designs and for its toughness, as it can be easily bent or twisted according to the requirements. In this type of alloy, the resistance is higher than aluminium alloys or the grey cast iron. Zinc die casting products are low heat conductors, which means the zinc die casting components will last 10 times longer than the other metals like aluminium and magnesium.  


    2. Great Fluidity:

    One of the major reasons people choosing zinc is that it has great fluidity. The incredible fluidity or “cast ability” of zinc, allows die casting to achieve accurate dimensions. If you are using zinc, for the die casting method, then you don’t need to opt for any secondary options that are very much applicable for other materials like magnesium and aluminium alloys. Zinc die casting makes the components a bit lighter as less material is used, during the thin-wall application.


    3. Affordability:

    Zinc die casting requires minimum energy for smelting and casting of the product. As the melting point of zinc is low, which helps in saving energy. It is more affordable, than the other metals like aluminium and magnesium.


    4. Wide Range of Surface Treatment Options:

    Zinc die casting products offer various surface treatment options like zinc plating, painting, silver plating and gliding. In various industries, like automotive industry zinc alloys are used for various finishing methods. Another major benefit of zinc die casting is that, the die casting components can achieve various aesthetic finishes with less preparatory work.


    5. Increase in Market Demand:

    Zinc die casting products are extensively used in making a variety of products like toys, important electrical products and components, drop handles, name plates, knobs and many others. It is considered a rigid engineering material, because of its stronger elasticity than the other alloys like aluminium and magnesium.


    Thus, because of the above reasons zinc die casting has become widely popular in various industries.
