What kinds of casting are those?
two. Casting process usually includes: the mold (liquid metal casting vessel become solid) preparation, according to the material in the mold can be divided into sand, metal, ceramic, clay, graphite, according to the frequency of use can be divided into single type, semi permanent and permanent mold, mold preparation is Main factors influencing the quality of castings; casting the melting and casting of metals, metal (alloy) main cast iron, cast steel and cast nonferrous alloy castings; the processing and inspection, casting processing cores and casting surface including the removal of foreign body, resection of sprue, grinding burrs and fash protrusions and heat treatment plastic, anti rust and rough machining.
The casting process can be divided into three basic parts, namely casting metal preparation, preparation and casting mould processing. Metal casting refers to casting pouring casting metal material used in the production, it is a kind of metal elements as the main ingredient, and adding other alloy metal or non-metallic elements formed, known as customary the main cast alloy, cast iron, cast steel and cast nonferrous alloys.
There are many kinds of casting, according to the modeling method used to be divided into: ordinary sand casting, including wet sand, dry sand and sand. The 3 kinds of chemical hardening special casting, special casting press molding materials can be divided into natural mineral sand as the main materials (such as casting, casting, casting, mud the workshop of shell casting, vacuum casting mold casting, ceramic mold casting, special casting and metal) as the main cast materials (such as metal casting, pressure casting, continuous casting, low pressure casting, centrifugal casting, etc.)
