Casting Process Optimization
the problemA 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 (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 solutionThe challenge in producing the six heatsink pads was to maintain the profile tolerance to the 6 pads to within .4mm to 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.
PHB uses internationally recognized MAGMAsoft® simulation technology to optimize tool design and casting quality. Its optimization capabilities provide a better understanding of mold filling, solidification, mechanical properties, thermal stresses and distortions, and much more. The fully integrated Autonomous Optimization Tool, CAD interfaces, and extensive databases, MAGMAsoft® provides a complete solution for design, production, and quality departments.
