Hiekan valu, joka tunnetaan myös nimellä hiekkavalettu valu, on ametal casting process characterized by using hiekka as the homettamateriaalia. Gravitycasting on yksi vanhimmista tunnetuista prosesseista metallien ja metalliseosten valmistuksessa. Siihen kuuluu sulan metallin kaataminen acrucible into a hometta under only the force of gravity, without the use of pressurized gases, vacuums, or keskipakoisvoima.
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 hometta with better surface quality and higher productivity.
Auwell is very strong in brass gravity & hiekka casting manufacturing. We are able to develop copper casting parts from traditional hiekka 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 hiekka-blasting, powder coating and polishing.
The popular material that we used for brass gravity & hiekka 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.
