Description
The gravity casting is one type of permanent mold casting, which has advantages of reusable mold, good surface finish, excellent dimensional accuracy and high production rates. The common metal casting material composes aluminum, aluminum alloy, and brass. Material selection is according to technical standards, including ASTM, ANSI, SAE, DIN and BS.

Features
1. Typical parts made by gravity casting includes machine components, various housings, motors, instrument enclosures, etc.
2. The brass gravity cast products are mainly used in fluid control system, such as brass valves, couplings and adapters.
3. Brass cast parts have a wide application in mine industry, oil field, fire fighting field, fluid pressure transmission parts, etc.
4. Besides brass valves, we also produce house decoration parts, brass cast kitchen parts and brass cast furniture parts.

Permanent Mold Casting Processes

Aluminum Gravity Casting
Advantage:
1. Its casting parts have excellent mechanical properties compared with that of die casting parts.
2. Because aluminum gravity cast parts has very lower porosity than aluminum die casting parts.
3. Be generally sound, provided that the casting aluminum alloys used exhibit good fluidity and resistance to hot tearing.
4. Mechanical properties of permanent mold castings can be further improved by heat treatment.

Brass Gravity Casting
Advantage: Brass gravity cast products have a much superior surface quality than that of brass sand cast products.
