Pressure Die Casting for High-Volume Metal Parts
Pressure die casting injects molten aluminum, zinc, or magnesium into hardened steel dies under high pressure, producing repeatable metal parts at volume.
The focus is on consistent fill, dimensional repeatability, and net-shape parts that reduce downstream machining.

Complete Die Casting Manufacturing Solutions
Aluminum Die Casting
High-pressure casting of aluminum alloys for lightweight, corrosion-resistant structural and functional components.
Zinc Die Casting
Hot-chamber casting of zinc alloys for thin-wall, high-detail parts with excellent surface finish and dimensional stability.
Magnesium Die Casting
Casting of magnesium alloys for the lightest structural metal parts, ideal for weight-sensitive applications.
Hot & Cold Chamber Casting
Process selection matched to the alloy — hot chamber for zinc and magnesium, cold chamber for aluminum at higher injection pressures.
CNC Finishing of Castings
Secondary machining of castings for critical tolerances, threads, and mating features that require precision beyond the as-cast condition.
Surface Finishing
Powder coating, anodizing, and plating to improve corrosion resistance, appearance, and wear performance of cast parts.
Process Capabilities
Die Casting Process Standards
Process selection and secondary operations are matched to the alloy and the part requirements.
| Process | Capability |
|---|---|
| Hot Chamber Casting | Suited to zinc and magnesium alloys at high production rates |
| Cold Chamber Casting | Suited to aluminum alloys requiring higher injection pressures |
| Multi-Cavity Dies | Multiple parts per cycle for high-volume production |
| CNC Finishing | Secondary machining for critical tolerances on cast features |

Applications
Parts We Commonly Cast
Die casting suits net-shape metal parts produced at volume across the industries we serve.
Housings & Enclosures
Net-shape metal housings for electronics, industrial, and consumer products.
Automotive Components
Structural brackets, housings, and powertrain-adjacent components.
Heat Sinks
Aluminum heat sinks with thin fins and high surface area for thermal management.
Industrial Components
Repeatable cast parts for machinery and equipment.
Consumer Product Parts
High-volume metal parts with consistent appearance and fit.
Production
From Die Design to Volume Casting
Die Design & Build
Die is designed and built to produce the part geometry at required volume.
Trial Casting
Initial castings are produced and evaluated against drawings.
Process Adjustment
Injection parameters are tuned to stabilise fill and reduce defects.
Dimensional Verification
CMM and optical projectors verify critical dimensions.
Volume Production
Casting continues with in-process checks for consistency.
The objective is to transition from trial casting to consistent production without repeated die correction.
Quality Assurance
ISO 9001 Quality Management
Certification is only meaningful when it changes how parts are cast and verified. Here is what it means for your project.
Documented Quality System
Quoting, die build, casting, and inspection follow documented and audited processes.
Traceable Materials & Reports
Material certifications and First Article Inspection documents accompany each batch.
Consistent Inspection
CMM and optical measurement projectors verify critical dimensions against drawings.
