Advantages Of Aluminium Die Castings

- Aug 07, 2017 -

Aluminum is a kind of pressure casting parts, is the use of pressure casting machinery installed die casting, die casting machine, feeding the heating aluminum or Aluminum Alloy pouring liquid into the die casting machine, die casting machine by die casting, casting out of shape and size of the aluminum mold limit Aluminum Alloy parts or parts, such parts usually called aluminum die-casting.

Advantage:

(1) it can make metal parts with complex shape, clear outline and thin wall and deep cavity. Because molten metals maintain high fluidity at high pressure and high speed, they can obtain metal parts which are difficult to be machined by other process methods.

(2) the dimension precision of die casting parts is higher, and can reach IT11 - 13, sometimes up to IT9, and the surface roughness is up to Ra0.8 - 3.2um, and the interchangeability is good.

(3) material utilization rate is high. Because of the high precision of the die castings, it can be assembled and used only after a small amount of mechanical processing, and some die castings can be assembled directly. The utilization ratio of the material is about 60%--80%, and the utilization ratio of semifinished material is 90%.

(4) high production efficiency. Because of the high speed mold filling and short filling time, the metal industry is rapidly solidified, and the cycle speed of the die casting operation is fast. Among various casting processes, the die casting method has the highest productivity and is suitable for mass production.

(5) it is convenient to use inserts. It is easy to set the positioning mechanism on the die casting die to facilitate the inlay and casting of the insert so as to meet the requirements of the local special performance of the die castings.
