Low Pressure 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.

In low pressure die casting, 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 casting.

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

Method: Low pressure die casting

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

Low pressure die casting is competitive casting method when the production quantity is relatively small and/or when heat treatment is needed to improve the mechanical properties.
