Metal casting process Introduction  from Hengrui Casting

Metal casting is the molten metal poured into the metal to obtain castings parts,this method produces a fine crystal casting,good mechanical properties, high dimensional accuracy and low surface roughness.
What's more,Metal mold can be reused,used in non-ferrous alloys and small simple castings in mass production processes.

Metals casting advantage:

1.Metal mold can be used even up to 10,000 times,save a lot of modeling materials and time.
2.Metal-type casting parts to speed up the cooling rate,casting parts  internal tissue dense,Improve the mechanical properties of cast parts.
3.Casting parts dimensional tolerances reach IT 12 ~ IT 14,Surface roughness reached Ra 25~12.5. Metals casting will reduce the machining allowance,save metal materials and processing costs.
4. After the casting can be combined directly to continue pouring,high productivity.


Metals casting disadvantages:

1.Metal casting cost is high,long period,and Metal type is not compromise, breathable performance, so that casting parts prone to cracks, pores and other defects.

Metal casting is mainly applied to non-ferrous alloy castings of mass production,such as Aluminum piston, cylinder block ,Cylinder head, pump casing, small and medium-sized castings.
Most of the customers are adding these orders recently.
