The manufacture of an embryonic hair used for important parts, such as shafts, gears, etc..Casting can produce parts with complex shapes, so it is often used in the manufacture of the rough embryo of the parts with low mechanical performance. For example, machine tools, housings, etc..These two words were searched on the internet,1. I would like to ask, washer, nut, daily life mug, kitchen knife, thermos bottle and so on is casting or forging skin?2. give me more examples of casting and forging to help me understandThank youI've got all my share
For complex shapes, especially those with complex internal cavities, the casting process is usually used. The casting parts have wide adaptability and good comprehensive mechanical properties.But in the mechanical high load and the working condition serious important part, besides the simple shape may use the rolling plate, the profile or the welding piece, usually uses the forging. By forging can eliminate cast loose, metal welding holes, the mechanical properties of the forgings are generally better than the same material with other processing out of the parts.Definitions of casting and forging:Casting: the process of melting metal into a liquid that meets a certain requirement and pouring it into a mold. After cooling, solidification and finishing, a casting (parts or blanks) with a predetermined shape, size and performance is obtained. The basic process of modern machine building industry.Forging: it is a method of using a forging machine to exert pressure on a metal blank to produce a plastic deformation to obtain a mechanical property, a certain shape and a dimension.
Washer, nut, thermos mug, kitchen knife, the skin is rough forging. A general appearance is casting. Automobile engine cylinder is casting. Towers of steel for the general forging.
Dizzy, don't do upstairs yo.Gaskets are usually made of stamping, not forged or castNuts are generally cold heading and do not belong to hot forgingDaily life is a mug, stamping, forging or casting. Not.Kitchen knife should belong to forging forming, general kitchen knife should be clip steelA skin also belongs to the cold stamping.Here are some examplesForging: ax, connecting rod, crankshaft, rocker, steering knuckle, shift fork, stainless steel knife and forkCasting forming: machine bed, radiator, manhole cover, artware, bronze statue, cast iron pan
