Tooling lead time
100k–1M
Shots
Die casting punishes tooling. Our dies are designed around thermal balance, shot pressure and cycle time — not just the cavity geometry.
We engineer high-pressure dies with single or multiple cavities, hydraulic slides, vacuum-assisted filling, jet cooling and die-spotting access. H13, SKD61 and 8407 steels are heat-treated and stress-relieved for long shot life, with inserts and cores replaceable without scrapping the base.
Typical parts include automotive housings and brackets, LED and electronics bodies, power-tool components, locks and hardware. We support die design, trial, sample inspection and trim tooling as a single package.
✓ Filling, solidification and thermal simulation
✓ Vacuum and jet-cooling options
✓ Replaceable inserts and cores
✓ Die spotting, trial and sample reports
CAPABILITIES
What we deliver
Practical capabilities, matched to the tooling and the production volume — not a generic menu.
01
HPDC die design
Runner, gate, overflow and cooling layout optimized for filling and solidification.
02
Slides & cores
Hydraulic and mechanical slides for undercuts, holes and complex side features.
03
Vacuum-assisted casting
Vacuum valve and sealing design for low-porosity structural and leak-tight parts.
04
Thermal management
Jet cooling, baffles, thermal pins and die-temperature control for stable cycles.
05
Trim dies & fixtures
Matched trim tooling, checking fixtures and secondary-operation support.
06
Tryout & optimization
Die spotting, trial shots, porosity checks and process window development.

FAQ
Questions, answered.
Which casting alloys do you tool for?
Aluminum ADC12/A380/A356, zinc Zamak 3 and 5, and magnesium AZ91D/AM60 are the most common. We select die steel and thermal design based on the alloy and wall thickness.
Can you reduce porosity in structural parts?
Yes. Vacuum-assisted filling, optimized overflows, jet cooling and die-temperature control are used together to minimize air entrapment and shrinkage porosity.
Do you build the trim die as well?
Yes. Trim dies, checking fixtures and secondary machining fixtures can be delivered with the die as a complete production package.
How do you validate a new die?
We run trial shots, inspect critical dimensions, check porosity where required, and document the process window before shipment. Samples are sent for your approval.
