Aluminum die-casting is a kind of pressure casting parts, is the use of casting mold casting pressure casting machine die-casting machine, will be heated to liquid aluminum or aluminum alloy pouring into the die-casting machine inlet, die-casting machine die-casting, casting mold limit The shape and size of aluminum parts or aluminum parts, such parts are usually called aluminum die-casting.
(1) can create a complex shape, clear outline, thin-walled deep cavity of the metal parts. Since the molten metal maintains high flow at high pressure and high speed, it is possible to obtain metal parts which are difficult to process by other process methods.
(2) die size of the higher accuracy, up to IT11-13 level, sometimes up to IT9 level, surface roughness up to Ra0.8-3.2um, good interchangeability.
(3) high material utilization. Due to the high precision of die casting, only a small amount of mechanical processing can be used to assemble, and some die castings can be directly assembled. Its material utilization rate of about 60% - 80%, rough utilization rate of 90%.
(4) high production efficiency. Due to high-speed filling, filling time is short, the metal industry solidification quickly, die-casting operation cycle speed. In all kinds of casting process, die-casting method of the highest productivity, suitable for mass production.
(5) easy to use inserts. Easy to set in the die-casting mold positioning mechanism to facilitate the embedded inlay inserts to meet the special characteristics of die casting special requirements.
