The causes of cracks and suggestion: 1. The structural design of the casting is unreasonable, with sharp corners, and the thickness of the wall changes too much. If cracks occur in this case, the structural design of the casting should be improved to avoid sharp corners, and strive to strengthen wall thickness and smooth transition. 2.Nov 08, 2020 · Aluminum alloys for high-pressure die casting (HPDC) usually contain sufficient quantities of dissolved iron to reduce die wear and soldering. Unfortunately, iron reduces ductility, making the product unsuitable for crash-resistant automotiveponents. Recent improvements in machine design and new alloys allow the production of high ductility, structural HPDC …To keep the die from deforming in the die casting, the molten metal can flow stably in the die, the casting can be cooled evenly, and the die casting can be fully automatic without failure. Besides, according to the production batch, material conditions and other reasonable selection of suitable mould materials. 1.Therefore, aluminum die castings are ideal for applications such as structural brackets, air/fuel deliveryponents, housings for numerous applications, as electrical connectors, heat sinks, and many others. Die casting is aplished by forcing molten metals into a mold/die form, using high-pressure systems.
