Aluminum Alloy Die Casting

Aluminum die casting alloys are lightweight and possess high dimensional stability for complex part geometries and thin walls. Aluminum has good corrosion resistance and mechanical properties as well as high thermal and electrical conductivity, making it a good alloy for die casting.

Our Alloys Include:
  • Aluminum: 360, 380, 383, 413, and A304 K-Alloy
  • Zinc-Aluminum: ZA-8, ZA-12, and ZA-27

Aluminum Die Cast Part Design Case Study

aluminum die cast part design

the problem

A global leader in automotive lighting came to PHB with the challenge of creating two castings – one for low beams and one for high beams. Because of the complexity in aligning the fixtures (die cast heat sink pads) for the LEDs, prior designs had only allowed them to have three heat-sink pads per casting. Since both the low beams and high beams required six heat sinks, each headlight required four castings. The problem compounded when the mirror design was required for left or right headlights. With the added expense of creating separate tooling for all of the castings, and the additional time and expense involved in aiming these eight castings, our customer realized it was time for a new solution.

the solution

The challenge in producing the six heatsink pads was to maintain the profile tolerance of the 6 pads to within .4mm of the datum structure. There are 17 individual features at each pad location, or 102 total features per casting that are critical to function. Any missing feature results in a part that our customer cannot fully assemble. PHB utilized the MAGMA process simulation and other camera quality inspection, close tolerance machining, and precision quality control to develop and produce a two-casting headlight assembly for our customer.
