    Zinc Die Castings for Every Industry

    Since its beginning, Simalex has evolved into a world-class leader in die casting. We’ve been utilizing our technological wherewithal and skilled professionals to manufacture high-quality zinc die castings for different industries.
    Zinc alloys have the broadest physical and mechanical properties. Our proprietary multi-slide die casting process and superior thin-wall capabilities make us the leading supplier of zinc metal castings for a broad range of consumer lighting devices. The castability of zinc, its wear resistance, and structural integrity are perfect for the creation of the multi-faceted, highly complex shapes used in railway and industrial products. Zinc alloys such as Zamak all use the hot chamber process, which allows for maximum casting speed.

    Advantages of Working with Zinc Alloy

    Zinc Alloys, including Zamak Series — No. 2,3,5, and 7 contains 4% aluminum and small amounts of magnesium to improve hardness and strength. According to experts, die-casters Zinc metal alloys are highly desirable for die casting parts. Characteristics that make zinc alloys extremely popular are:

    • High strength and stiffness 
    • Great electrical conductivity 
    • High thermal conductivity 
    • High dimensional accuracy and stability 
    • Great thin wall capability 
    • Ability to cold form, which eases joining 
    • High-quality finishing characteristics
    • Outstanding corrosion resistance 
    • Full recyclability 

    Zinc alloys are an ideal alternative to machined, pressed, stamped, and fabricated components. They allow for greater variation in section design and maintains dimensional tolerances better.
