The High Pressure Zinc Die Casting Process

High pressure die casting with zinc-based alloys is what A.M.E specialise in, die casting is one of the most efficient manufacturing processes that can produce strong geometrically complex metal components with steel die casting tools which are also known as moulds.

The process is carried out on our fully automated die casting cells suitable to withstand high pressure. The molten metal is pushed by a hydraulically actuated plunger into a two-piece die casting tool (also known as a tool or mould) containing one or multi impression cavities, each an exact inverse replica of the part or parts being produced.

Because of the fast chill and rapid solidification that takes place when molten metal comes in to contact with the die casting tool the cooling time can be anything from seconds to a minute dependant on the size and weight of the component.

When the component is cooled the machine will only then open the tool and the fully automated arm will reach in and take the component out of the die, lubricate the die casting tool and weight the component to ensure it is correct. Once the cycle is complete the machine will automatically repeat this process until the desired quantity is reached.

Why is High Pressure Zinc Die Casting the right process for your product?

  • The mechanical properties of high pressure die castings are generally superior to castings produced by other methods.
  • Economical – A die casting tool can run up to hundreds of thousands to millions of shots before it needs to be replaced. Perfect for high volume productions.
  • High pressure Zinc die casting has lower costs compared to other processes available.
  • Zinc can cast in thin wall sections therefore making it lighter in weight.
  • One of the most important advantagesof Zinc is its accuracy, in fact Zinc alloys allow closer tolerances than any other metal or moulded plastic
  • Zinc has good electrical and thermal conductivity properties.
  • Zinc is more cost effective for the raw material than its rivals
  • Low melting point, which means it requires less energy for production.
  • Strong stability, which makes for a long-lasting product with high quality finishing properties
