Zinc Casting Metals

Dynacast is a world leading precision zinc die caster. We have produced billions of zinc die cast components—from one hundredth of a gram to one kilogram in size.

Zinc alloy characteristics:

  • High strength and hardness
  • Excellent electrical conductivity
  • High thermal conductivity
  • Low cost raw material
  • High dimensional accuracy and stability
  • Excellent thin wall capability
  • Ability to cold form, which eases joining
  • High quality finishing characteristics
  • Outstanding corrosion resistance
  • Full recyclability
  • Zinc Creep

 

Zinc, although heavier than other metals, can be a superior option when it comes to strength and durability. And it can be more a cost effective option too. Zinc has a higher melting point than other metals — which means it uses less energy during the manufacturing process. Many manufacturers find die casting in zinc to be the ideal alternative to machined, pressed, stamped, and fabricated components. 

 

Applications for Zinc:

  • Complex net-shaped zinc housings, with precise thin walls offer excellent electrical performance and shielding properties
  • Our proprietary multi-slide die casting process and superior thin-wall capabilities make us the foremost supplier of zinc components for broad range of consumer electronic devices
  • The castability of zinc, its wear resistance, and structural integrity make it perfect for the creation of the multi-faceted, highly complex shapes used in automotive safety and electronics industry
