A Vacuum Die Casting Die works under heat and pressure, so the design problem is thermal: metal has to fill, freeze and release at a rate the cycle time depends on. The Vacuum Die Casting Die described here is built in maraging steel inserts at the gate and developed for automotive structural components. die design with flow simulation, EDM detail and thermal balancing is applied with tool life and the maintenance interval agreed before building starts.
The parts that matter most are the interfaces: bores, sealing faces, threads and mounting patterns. Those are held to cavity tolerance ±0.05 mm, verified against the drawing, and recorded before anything is packed.

Manufacturing process
The operation sequence is decided before the first chip is cut: roughing to leave even stock, semi-finishing, then die design with flow simulation, EDM detail and thermal balancing as the final operation. That order is what keeps cavity tolerance ±0.05 mm stable as the batch runs and the machine warms up.
Material is purchased against a certificate and checked on receipt, so the composition is known before any cutting starts. Work in progress is identified by part number and operation, and the finished parts are deburred, cleaned and protected before they leave the machine area.
Typical applications
Most of the work supplied in this category falls into the following examples.
- Structural automotive brackets.
- Heat sink and lighting housings.
- Gear box and pump bodies.
- Consumer appliance frames.
- Electric motor housings.
Quality control and documentation
Every batch is measured against the drawing with calibrated equipment, and results are recorded against the part number rather than kept on a scrap of paper.
Material certificates to EN 10204 3.1, dimensional reports and first article inspection reports are issued with the shipment where the application requires them. Calibration dates and measurement uncertainty are recorded alongside every result.
Ordering, lead time and packaging
Quotations are returned within one working day of a complete drawing package. Lead time is quoted from drawing approval, not from the date of enquiry.
Frequently asked questions
How is porosity controlled?
By gating and venting designed from flow simulation, plus vacuum assistance on structural parts. Impregnation is a repair, not a substitute for correct fill.
What die life should be expected?
Aluminium dies in H13 typically deliver 80,000 to 150,000 shots with scheduled maintenance. Zinc tools run longer because the melt temperature is far lower.
Can you supply material and inspection certificates?
Yes. Material certificates to EN 10204 3.1, full dimensional reports, first article inspection reports and, where required, PPAP or AS9102 documentation are issued with the shipment.
