What are the advantages of aluminum die-casting?
3, the economic effect of the fine: Because aluminum die-casting precise size, smooth sheet pan and so on. Generally no longer be machined directly use or processing volume is small, so not only improves the utilization rate of the metal, but also reduces the amount of processing equipment and labor; casting cheap price; combination of die-cast aluminum with other metals or non-metallic materials may be used . Saving assembly work and save metal.
2, high efficiency: high productivity machines, such as domestic JⅢ3 Horizontal cold air compressor machine aluminum die-cast aluminum can average 600 hours to 700 times, small hot chamber die casting machine aluminum die-casting aluminum can on average every eight hours from 3000 to 7000; long life die-cast aluminum type, a pair of die-cast aluminum type, die-cast aluminum alloy bell, life of up to hundreds of thousands of times, or even millions of times; easy to mechanization and automation.
Die-cast aluminum advantages:
1, good quality: high precision casting size, generally the equivalent of 6 to 7, even up to four; good surface finish, generally the equivalent of 5 to 8; high strength and hardness, strength is generally increased by 25 than sand casting to 30%, but the elongation decreased by about 70%; dimensional stability, good interchangeability; die-cast aluminum can be thin-walled complex castings. For example, the current zinc alloy die-cast aluminum minimum wall thickness of up to 0.3mm; aluminum alloy castings of up to 0.5mm; the smallest aperture is cast 0.7mm; minimum pitch of 0.75mm.
