Die-cast aluminum advantages:

1. High-quality products: Castings feature high dimensional accuracy, generally equivalent to 6-7 levels, even up to 4 levels; excellent surface finish, typically 5-8 levels; high strength and hardness, with strength generally 25-30% higher than sand casting, but elongation reduced by about 70%; stable dimensions with good interchangeability; capable of pressure casting thin-walled and complex aluminum castings. For instance, current zinc alloy pressure-cast aluminum parts can have thin walls as thin as 0.3mm; aluminum alloy castings can reach 0.5mm; small casting hole diameter of 0.7mm; and small pitch of 0.75mm.

2. High Production Efficiency: Machines have high production rates, for instance, the domestically produced JⅢ3 horizontal cold chamber die casting aluminum machine can cast aluminum 600 to 700 times on average every eight hours, while a small hot chamber die casting aluminum machine can cast aluminum 3,000 to 7,000 times every eight hours; the lifespan of aluminum die casting molds is long, with a set of aluminum die casting molds and aluminum alloy, the lifespan can reach tens of thousands, even hundreds of thousands of times; easy to achieve mechanization and automation.

3. Excellent Economic Performance: Due to the dimensional accuracy, smooth surface finish, and other advantages of die-cast aluminum parts, they are generally used without further mechanical processing or with minimal processing, thus enhancing metal utilization and reducing the need for a large number of processing equipment and labor hours. Castings are cost-effective; they can be combined with die-cast aluminum to incorporate other metals or non-metallic materials, saving both assembly time and metal.
