Zinc and aluminum alloy die -casting process is developing so quickly.sheet metal forming services

　　At present, large and small electrical products and hardware parts in life are made of zinc and aluminum alloy die -casting process. So why are zinc and aluminum alloy die casting easily develop so quickly and widely apply it?

　　1. Good product quality

　　There is a high size and accuracy, which can reach CT4 ～ CT8 level, the surface roughness RA value is 0.8 to 6.3 μm, and the minimum RA value reaches 0.2 μm. They are relatively high, and the strength is generally 25%to 30%higher than the sand casting, but the extension of the extended aluminum is reduced by about 70%. The size is stable and the interchangeability is good. It can reach 0.3mm, aluminum alloy castings can reach 0.5mm, minimum casting diameter is 0.7mm, and the minimum snail distance is 0.75mm.

　　2. High production efficiency

　　Machine production efficiency is high. Generally, the average horizontal cold room die-casting machine can die 600-700 times, and the average 8h of small hot room die-casting machine can die 3000-7000 times, die casting mold life, a pair of pressure casting, die casting aluminum alloy, life span It can reach hundreds of thousands of words, or even millions of times, suitable for large -scale production, and can achieve a multi -cavity process. Its output increases and increases more than the increase, which is easy to achieve mechanization and automation.

　　3. Economic effects

　　Due to the advantages of accurate size of the die -casting and smooth surface, it can generally be used directly without mechanical processing, or the processing volume is small, so it not only improves the metal utilization rate, and reduces a large number of processing equipment and working hours. The price of casting is cheap. A combination of die -casting, embedded with other metals or non -metal materials, which saves assembly workers and saves metals.
