Gravity Casting (Permanent Mold Casting)Service of Qingdao TianHua YiHe Foundry Factory

The gravity casting is one type of permanent mold casting. The gravity casting main advantages are the reusable mold, good surface finish, good dimensional accuracy, and high production rates.

Aluminum Gravity Casting:

Good Mechanical Property Compared with Aluminum Die Casting:
Aluminum gravity casting parts have excellent mechanical properties compared with that of die casting parts. Because aluminum gravity casting parts has very lower porosity than aluminum die casting parts. ALuminum gravity castings are generally sound, provided that the casting aluminum alloys used exhibit good fluidity and resistance to hot tearing. Besides,mechanical properties of permanent mold castings can be further improved by heat treatment.

Brass Gravity Casting:

Brass gravity casting can also be called brass permanent mold casting. Brass gravity cast products have a much superior surface quality than that of brass sand cast products. The brass gravity cast products are mainly used in fluid control system, such as brass valves, couplings and adapters. Such brass cast parts have a wide application in mine industry, oil field, fire fighting field, fluid pressure transmission parts and etc. Besides brass valves, we also produce house decoration parts, brass cast kitchen parts, and brass cast furniture parts. We can be customized according to customer requirements and drawings.
