Brass casting is an early hot processing technology. Brass casting process has about 6,000 years of history. Brass casting process definition: refers to the melting to liquid brass is poured into a specific shape of solid brass casting and solidification processing. Other than the cast brass or copper, iron, aluminum, Tin and lead Foundry. Common mold materials are sand, clay, water, glass, resins and other supporting materials. Special casting molds include: investment casting, lost foam casting, metal casting, ceramics, casting, etc. (Sands including: quartz sand, magnesia, zirconia, chromite sand magnesium olivine sand, kyanite, and sand, graphite, iron ore and other).
Casting process can be divided into three major parts, namely, metal preparation, mold preparation and casting process. Cast metal is used to cast casting castings of metal materials, it is a metallic element as the main ingredients, and join the other metal or non-metallic elements and alloys, customarily referred to as casting alloys, mainly in cast iron, cast steel and casting Nonferrous alloy.
Brass casting process of low temperature: generally it is 960 degrees, almost crystallized, at least 980, the casting temperature is the lowest, this is high zinc brass, low zinc brass is also high.
Brass casting advantages: low cost, processing flexibility, you can obtain complex shapes and large castings, machinery manufacturing accounts for a large proportion of anti-sperm such as machine tools, cars, 25% tractor 50~60%.
