Casting range of applications and characteristics?
large-scale: for mass production, the small cast, a variety of materials. Process characteristics: hand: a flexible, easy, but inefficient, labor-intensive, low-dimensional accuracy and surface quality. Mechanical: dimensional accuracy and surface quality, but large investment. Metal Casting: Scope: small quantities or mass production of non-ferrous alloy castings, but also for the production of steel castings. Process characteristics: precision casting, surface quality, compact structure, mechanical properties, high productivity. Casting: Scope of application: all kinds of bulk melting point of steel and alloy precision castings of small complex, especially for casting art, precision mechanical parts. Process characteristics: size, high precision, smooth surface, but many processes, labor-intensive. Ceramic mold casting: Scope: mold and precision castings. Process characteristics: size, high precision, smooth surface, but low productivity. Low Pressure Casting: Scope: small quantities, preferably large quantities of large and medium-sized non-ferrous alloy castings, to produce thin-walled castings. Process characteristics: casting dense and high technology produced equipment is relatively simple, can be all kinds of mold, but low productivity. Pressure casting: Scope: mass production of a variety of small and medium sized non-ferrous alloy castings, thin-walled castings, pressure castings. Process characteristics: high precision casting size, surface smooth, compact structure, high productivity and low cost. However, the high cost of die-casting machine and the mold. Centrifugal Casting: Scope: small quantities to large quantities of rotating body castings, pipe fittings of various diameters. Process characteristics: high precision casting size, surface smooth, compact structure, high productivity. Continuous casting: Scope: Fixed a long-shaped cross-section castings, such as steel ingots, steel etc. Process characteristics: compact structure, mechanical properties, high productivity. LFCCast: Scope: different quantities of the more complex variety of alloy castings. Process characteristics: a high dimensional accuracy casting, casting a large freedom of design, process is simple, but looks like burning affect the environment.

Standard casting tolerances ?
According to GB/T6414-1999, with reference to the casting material, casting, casting conditions and other selected tolerance level CT, CT selected according to the corresponding size tolerance level tolerance values.
