Forging production is one of the main processing methods to provide mechanical parts blank in the mechanical manufacturing industry. Through forging, not only the shape of mechanical parts can be obtained, but also the internal structure of metal can be improved, and the mechanical and physical properties of the metal can be improved.
There is distinct difference between hot metal forging and cold forging die. To be specific, the precision cold forging compress the products at room temperature which can not form a more complex shape than in hot forging process.
Generally, the important mechanical parts with high stress and high requirements are mostly manufactured by forging production method. The turbine generator shaft, rotor, impeller, blade, retaining ring, large hydraulic press column, high-pressure cylinder, rolling mill roll, internal combustion engine crankshaft, connecting rod, gear, bearing, etc., are all produced by forging.
The quality of impression die forging is less than 1kg, as large as hundreds of tons; it can be produced in a single piece, small-batch, and mass production;
The use of precision die forging can make the size and shape of the forging stainless steel close to the finished parts, so it can greatly save metal materials and reduce cutting processing hours;
