The Indispensable Manufacturing Technology Of High-quality OEM Aluminum Die Castings

Update:17 Jul 2020

Technical requirements of OEM Aluminum Die Castings mainly include mechanical properties, die-casting dimensions and surface quality. Aluminum die-casting products mainly include auto parts, electronics, sporting goods, photographic supplies, fishing equipment, lighting, various electric tools, electrical products, motorcycle radiators, speaker covers, LED lamp housings, and cameras. In equipment, radiators, electronic communication equipment, electronic game machines and other industries, some high-performance, high-precision, high-toughness and high-quality aluminum die castings are also used in high-demand industries such as large aircraft and ships.

1. mechanical properties: when die-casting test pieces are used, the mechanical properties must meet the requirements of gb/T15115. The mechanical properties of the cut-off sample at the designated position must be at least 75% of that of the single casting sample.

2. Profile aluminum: national standard aluminum is adopted, whether to determine the quality and cost of products/Many non-standard recycled aluminum are in the current market, and ordinary consumers can't identify the post-treatment.

3. Surface quality, casting dimensional accuracy and low surface roughness: the casting surface roughness must meet the requirements of gb6060.1. Castings, cracks, casting, looseness, bubbles, any penetrating defects, scratches, dents, shortage of meat, and no defects such as grid are allowed.

4. Die casting size: the shape and size of die casting shall conform to the specifications of casting drawings. The dimensional tolerance of OEM aluminum die castings and castings must comply with GB 6414. If there are special regulations and requirements, they should be shown in the drawings. Die casting dimensional tolerance does not include casting spacing. If die casting requires machining, the machining cost shall comply with gb/T11350.
