Brass Gravity & Sand Casting

Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. Gravity casting is among the oldest known processes for fabricating metals and metal alloys. It involves the pouring of molten metal from a crucible into a mold under only the force of gravity, without the use of pressurized gases, vacuums, or centrifugal force. 

Sand casting is commonly using for parts that have considerable big size which is not suitable for other casting method，or the parts have very small quantity that not worth to be made by gravity casting. Gravity casting use steel mold with better surface quality and higher productivity.

Auwell is very strong in brass gravity & sand casting manufacturing. We are able to develop copper casting parts from traditional sand casting technology (aluminum tooling), gravity casting (Steel tooling), shell tooling casting and low pressure casting. We have professional manufacture specially for after-casting process including machining, fine sand-blasting, powder coating and polishing. 

The popular material that we used for brass gravity & sand casting are copper, Bronze C95200, C83600, C90700 etc, also, brass and cupronickel C99700 etc.

The material to be used would be in accordance with clients’ specifications, or , Auwell engineers may introduce the best suitable material based on the nature of the products.
