Frequently Asked Questions

What alloys can your die casting molds accommodate?

Our die casting molds are engineered for aluminum alloys (A380, ADC12, AlSi9Cu3), zinc alloys (Zamak 3, 5, 7), magnesium alloys (AZ91D, AM60B), and copper-based alloys. Material selection depends on your application requirements including strength, weight, corrosion resistance, and thermal properties.

How do you ensure mold longevity under high-temperature conditions?

We utilize premium hot work tool steels like H13 and 8407 with optimized heat treatment protocols. Advanced cooling channel design manages thermal loads effectively, while optional surface treatments like nitriding or PVD coating enhance wear resistance. Regular thermal analysis validates design integrity.

Can you design molds for complex geometries with undercuts?

Yes, we specialize in complex mold designs incorporating side actions, hydraulic cores, and collapsible cores for parts with intricate features and undercuts. Our engineering team optimizes actuation mechanisms for reliable operation and minimal cycle time impact while maintaining dimensional accuracy.
