Low-pressure Die-casting

Competitive casting method when the production quantity is relatively small or when heat treatment is needed to improve the mechanical properties.

In the low-pressure die-casting process, the metal is transferred from an airtight furnace through a rising tube into a metallic tool. The casting temperature is about 750°C.

The molten metal is pushed upwards into the die with low pressure. The mould is filled up slowly, which ensures the solidity of the part with no unwanted porosity or entrained gases.

Low-pressure die-casting is a competitive casting method when the production quantity is relatively small or when heat treatment is needed to improve the mechanical properties. The tolerances and the surface finish are the same as achieved by gravity die-casting. The tooling costs are somewhat higher than by sand casting.

We have extensive experience in low-pressure die-casting. Even the most challenging parts can be manufactured at our plants by using sand cores in low-pressure die-casting.

For many of our clients, low-pressure die-casting is an excellent step towards bigger volumes. The cost of creating the mould is lower than in high-pressure die-casting, and yet the method is well suited for moderate mass production.
