Advantages of Die Casting-1

Die casting is a forming processing that fill the liquid or semisolid metal in a die cavity with very high speed, under high pressure, after cooled down, and get a finished geometry. So, high pressure and high speed inspection are the two features of die casting. In die casting, inspection pressure always ranges from several thousands to dozens of thousands Kpa. At the same time, its inspection speed is around 10-50m/s, sometimes will go over 100m/s. Therefore, filling time cost few, always in 0.01-0.2s.

Compared with liquid forming processing, die casting have follow advantages:

1, Good quality

1) High accuracy, will go up to IT11-IT13，even IT9.

2) Good surface roughness, always in Ra0.8-3.2µm, Ra0.4µm in maximum.

3) Compact texture, high strength and hardness. Liquid metal is cooled down under high pressure, and the filling time cost few, cooling speed is very fast, which result in a smooth and compact surface, and that will improve the wear resistance and corrosion resistance, also the hardness.

4) Stable dimension, good uniformity

5) Liquid metal will flow fast under high pressure, which will achieve metal parts with complex geometry, thick walls and deep holes, these parts other processing can manufacture easily
