High vs Low Pressure Die Casting
High Pressure Die Casting
A precision manufacturing process that involves injecting molten metal into a steel die or mold at extremely high pressures, typically ranging from 1,000 to 20,000 psi.
- Faster injection speed and cooling rate
- Wall thickness 0.08 to 0.16 inches
- Higher dimensional accuracy
Low Pressure Die Casting
Molten metal is gently poured and propelled into a mold with low-pressure gas at 7-30 PSI. Better suited for complex geometries and allows undercuts.
- Injection pressure 5-30 PSI
- Wall thickness over 0.18 inches
- Supports undercuts and complex shapes

Post-Casting CNC Machining
We offer the equipment and processes to handle all your CNC machining needs after die casting. Sometimes a part requires clean up or detailed features to be machined post-casting.
5-Axis Machining Centers
For complex geometries requiring multi-angle machining in a single setup.
Wire EDM & Graphite Machining
For fine details and intricate features that require precision cutting.
Reliable Die Casting Quality
Our commitment to maintaining rigorous appearance standards and rejection criteria ensures the final product consistently meets customer expectations.
