Low Pressure Die Casting - superior properties for complex, high-integrity parts.
The critical space between gravity die and high pressure.
Low pressure die casting (LPDC) fills the die from below using controlled low-pressure gas - rather than injecting under high pressure or relying on gravity. The controlled, turbulence-free fill produces components with excellent mechanical properties, reduced porosity and superior structural integrity compared to gravity die casting.
LPDC occupies a critical space between gravity die casting and HPDC - ideal for components that demand strength and integrity but have geometries or volumes that don't suit high-pressure processes.
- 01Components requiring superior mechanical properties - high-stress, structural or safety-critical applications
- 02Complex shapes with uniform wall sections where porosity must be minimised
- 03Automotive wheel and suspension components, hydraulic housings, aerospace structural parts
- 04Medium volume production where casting quality cannot be compromised
Dedicated LPDC Machine

As one of only a small number of UK foundries to operate LPDC alongside HPDC, gravity die and sand casting, Alucast can genuinely advise on the right process - rather than pushing every enquiry towards the process it's most familiar with.
