Dalian Aluminum Die Casting Product Selection Guide: Performance Indicators and Quality Identification Points

Dalian Aluminum Die Casting Product Selection Guide: Performance Indicators and Quality Identification Points

Aluminum die-casting products are widely used in industrial manufacturing and daily life due to their lightweight and high-strength characteristics. However, the quality of products in the market varies greatly. Only by mastering performance indicators and quality identification points can high-quality and reliable aluminum die-casting products be selected.

Strength and hardness are core performance indicators. High quality aluminum die-casting products need to have sufficient strength to withstand pressure and impact during use, such as key components such as car engine cylinders. Insufficient strength can easily lead to cracking. You can check the product material specifications, such as common aluminum alloy grades like ADC12 and A380, and different grades correspond to different strengths and toughness. At the same time, hardness affects the wear resistance of products, which can be easily tested with a hardness tester or observed for scratches on the surface of the product.

 

The dimensional accuracy of Dalian aluminum die-casting determines the adaptability of the product. Precision aluminum die-casting products have extremely high dimensional requirements in fields such as electronic equipment and medical devices. When making a purchase, it is necessary to use tools such as calipers to measure key dimensions and compare them with the design drawings. Excessive deviation may lead to installation difficulties or functional failure. The surface quality cannot be ignored either. Qualified products should have no defects such as pores, sand holes, cracks, etc., and the surface should be smooth and flat. If obvious dents, bubbles, or rough particles are found on the surface of the product, it may be due to poor die-casting technology, which affects its appearance and service life.

In addition, attention should be paid to the corrosion resistance of the product. Aluminum die-casting products are often exposed to air and are prone to oxidation and corrosion. This can be achieved by observing whether the surface has undergone anti-corrosion treatments such as anodizing and electroplating, or by inquiring about the corrosion resistance testing standards of the supplier's products. By comprehensively considering these performance indicators and quality identification points, and checking from multiple aspects such as material, size, surface, and corrosion resistance, it is possible to avoid stepping on pits when purchasing aluminum die-casting products and select high-quality products that meet the requirements.
