Die Casting Materials


Aluminium Die CastingA380, 383, A413, A360, CC401Aluminium die cast alloys are lightweight and can withstand some of the highest operating temperatures. Its great strength-to-weight ratios, make it popular for automotive components and aerospace applications.
Magnesium Die CastingAZ91D, AM50A, AM20, AM60BMagnesium die cast alloys are strong, rigid materials that have good corrosion resistance. They are typically used for electronic products.
Zinc Die CastingZamak 3, Zamak, 2, Zamak 5Zinc die cast alloys are typically lower in cost compared to aluminium and magnesium. They offer good stability and have excellent electrical and thermal conductivity, making them popular for under-the-hood parts and electrical applications.

How It Works

A mould tool is first manufactured by HLH’s highly skilled toolmakers and engineers. It is then installed on a die casting press and molten metal is injected under high pressure into the tool cavity. The parts can then be finished in a range of ways including powder coating and anodizing.

Why Choose Die Casting

Die Casting vs Metal Injection Moulding
Metal injection moulding, or MIM, is intricate and requires several steps to create parts. It is well suited for small intricate parts and large volume manufacturing. In comparison, die casting, has fewer steps and is economically feasible for smaller and larger runs when compared with MIM. It is used for creating larger geometrically complex components.

Die Casting is Used For
Producing (up to 100,000+) complex-shaped, industrial grade metal parts from real materials. Die casting is commonly used for making automotive components and decorative hardware.

Advantages of Die Casting

  • Lower cost per part
  • Accurate and repeatable
  • Good surface finish and range of treatments
  • Good for larger and more complex parts


Die cast parts are made in steel moulds, similar to those used in injection moulding, but use low melting point metals such as aluminum and zinc instead of plastics. More metal parts are made by die casting than by any other casting process.

To create the die cast part, molten metal is forced into a mould via high hydraulic or pneumatic pressure. These steel moulds, or dies, produce extremely complex, high tolerance parts in a repeatable process.

Hot Chamber Die Casting

Also known as gooseneck casting, hot chamber is the most popular die casting process. A chamber of the injection mechanism is immersed in molten metal and a “gooseneck” metal feed system brings the metal into the die cavity.


Cold Chamber Die Casting

Sometimes it makes sense to bring production back closer to home and when it does, HLH is on hand to support with our export metal mould tooling service.

Due to its versatility, reliability and accuracy, die casting is widely used for many applications across different industrial sectors, including the automotive, medical, and electronics industries.
