What are the technical requirements for aluminum alloy die casting?

The technical requirements of aluminum alloy die casting mainly include mechanical properties, die casting size and surface quality. 1. mechanical properties: when tested with die-casting samples, the mechanical properties shall conform to GB/T 15 1 15. When the die casting body is used for test, the mechanical properties of the samples cut from the designated parts should not be less than 75% of the single casting samples. Aluminum alloy die casting in Dongguan.

2. Size of die casting: The geometric shape and size of die casting shall conform to the provisions of casting drawings. The dimensional tolerance of aluminum alloy die casting shall be implemented according to GB64 14. If there are special regulations and requirements, they should be indicated on the drawings. Dimensional tolerance of die casting does not include casting inclination. When the die castings need to be machined, the machining allowance shall conform to GB/T 1 1350.

3. Surface quality, high dimensional accuracy of castings and low surface roughness: the surface roughness of castings shall conform to GB6060. 1. Castings are not allowed to have cracks, under-casting, air holes, bubbles and any penetration defects, as well as scratches, depressions, lack of meat and net burrs.

Aluminum alloy die-casting products are mainly used in traffic signal lamp housings, handles, fishing boat accessories, outdoor locks, electrical products, communication equipment, kitchen accessories, motorcycle radiators and horn covers, LED lamp housings, camera equipment, heat sinks, auto parts, electronic communication equipment, electronic game machine housings and other industries. Some high-quality aluminum alloy products with high performance, high precision and high toughness are also used in industries with high requirements such as large aircraft and ships.
