Our Die Casting Processes
Zorapid deliver high-precision, cost-effective parts via full-range professional die casting processes for diverse industrial applications.
High Pressure Die Casting
- Application: Mass-produced complex thin-walled aluminum/zinc housings and EV structural components
- Pros: 30–60s single cycle, dense castings, low per-unit cost, ideal for 1k–1M piece runs
- Applicable Materials:A380, A356, Zamak 3/5 Zinc Alloy
Vacuum Die Casting
- Applicable to: automotive power housings, medical airtight components, heat dissipation cavities
- Advantages:Eliminate air porosity, improved tensile strength, leak-proof performance
- For sealed pressure-resistant parts, X-ray porosity checked
Die Cast Alloys We Work With
Advantages of CNC Secondary Machining
- Tight tolerances precise sizes for assembly.
- Makes threads holes slots and flat sealing surfaces impossible to cast directly.
- Removes casting flash, draft slopes and uneven rough surfaces.
- Fixes shrinkage & deformation from die casting.
- Stable repeatability for mass production.
- Smoother base for better surface finishing.

FAQ
What drawings do I need to get a die casting quote?
STEP/IGS CAD files, 2D drawings with tolerances, material grade, order volume & finishing requirements. We offer free DFM design review.
What’s the minimum order quantity for die casting?
No strict MOQ; small batch prototype & mass production both supported. Rapid mold for low-volume runs.
What’s the typical lead time for molds & samples?
Prototype mold: 3–7 working days; production mold 10–15 days; samples delivered within 1 day after mold completion.
Can you produce leak-proof vacuum cast aluminum parts?
Yes, vacuum die casting eliminates internal porosity, suitable for hydraulic, EV cooling and medical sealed components.
Do you provide third-party inspection reports?
All orders come with FAI, material cert, CMM dimension report, X-ray test records upon request.
What tolerances can you achieve on die cast parts?
Standard ±0.08mm; precision CNC post-machining tightens tolerance to ±0.03mm.
