High-pressure Die-casting Machine
Automated
Casts end caps from molten ADC12.
✓ Expert reviewed All content on this page has been reviewed by a senior motor engineer.
Selection criteria
Locking force, real-time shot control, vacuum assist.
Supply chain
Shenzhen, Foshan and Dongguan are the main bases of China's die-casting machine industry, including a listed Foshan maker. Shot control and vacuum assistance decide porosity, which matters most at the bearing seat.
Buyer FAQ
- What clamping force is needed for motor end caps and housings?
- Small end caps usually run on 160–400 t machines; larger housings and integrated motor-gearbox cases need 500–1,000 t. Size from projected area × cavity pressure with margin, and check the shot capacity for the part plus runners and overflows.
- How do I keep porosity out of the bearing seat?
- Use real-time shot control, vacuum assistance where the part allows it, local squeeze pins at thick sections, and good thermal control of the die. Verify with X-ray at start-up and after die changes, and leave enough machining stock to clean up surface porosity.
- Cold-chamber or hot-chamber?
- Aluminium alloys such as ADC12 must use cold-chamber machines; hot-chamber machines are for zinc and magnesium alloys.
