Casting is a metal smelting meet certain requirements in liquid and poured into the mold, solidified by cooling to obtain a predetermined shape, size and performance of the casting process after clearing the whole deal. Casting blank due to the near molded or machined to achieve a small amount of free machining purposes and to reduce the cost of reducing the time to some extent. Casting is one of the foundations of modern manufacturing technology industry.
Casting is more economical methods of rough shape, for the shape of complex parts can show its economy. Such as automotive engine blocks and heads, ship propellers and exquisite works of art. Some difficult cutting parts, such as gas turbine nickel-based alloy parts can not be formed without casting method.
In addition, casting parts to adapt to the size and weight of a wide range of metal species almost unlimited; parts at the same time with the general mechanical properties, but also with wear, corrosion resistance, overall performance, shock-absorbing, is the other metal forming methods such as forging , rolling, welding, punching, etc. can not. Therefore, the machine used in the manufacturing process for the production of rough casting parts, in the number and tonnage remains by far the largest.
Many different types of casting, press molding method used to be divided into:
An ordinary sand casting, including wet sand, dry sand and chemical hardening sand three categories.
2 special casting, press molding materials can be divided into natural mineral sand as the main form of special casting material (such as investment casting, cement casting, foundry shell casting, vacuum casting, solid casting, ceramic casting, etc.) and metal as the main special casting mold materials (such as metal casting, pressure casting, continuous casting, low pressure casting, centrifugal casting, etc.) categories
Casting and other processes different characteristics, mainly adaptability, materials and equipment required more environmental pollution. Casting will generate dust, harmful gases and noise pollution on the environment, compared to other mechanical manufacturing processes to be more serious, need to take measures to control it.
