Forging Teeth vs Casting Teeth
Forging is processing way that putting pressure on metal blank by forging machinery, making it produce plastic deformation, in order to obtain certain mechanical properties, a certain shape and size of forgings. Forging can eliminate the as-cast osteoporosis of the metal, welded holes, and generally mechanical properties of forging is better than that of the same material of the casting.So for those important components that require to undertake high mechanical load, or working in serious conditions, in addition to simple shape rolling plate, or welding parts are available, all will consider forging process.
Casting is a metal forming process that melting the metal into certain requirements of the liquid and then pouring it into the mold,after cooling solidification,we can get desired shape and sizes.Production cost of blanks produced by casting is low.For complex shape, especially the parts with complex inner cavity, casting can show its economical efficiency more; At the same time, it has a wide adaptability,and has better comprehensive mechanical properties. But materials that needed in casting production and equipments (such as metallurgical furnace,sand mixing machine,molding machine, core making machine, shakeout machine, shot blasting machine, etc.) will produce dust, harmful gas and noise.Thus it will do harm to environmental.
Forging Teeth vs Casting Teeth
Casting
Casting is the oldest metal processing process that first melting metals into liquid status, then pouring metal liquid in injection moulds, and cooling a while to obtain the required shape or dimensions. When products are not suitable for forging, casting is the economic method for blank shape. Especially for complex shape parts, casting can show its efficiency more.
Size and weight range of casting parts is very wide, almost unlimited metal species; Parts that have general mechanical properties, but also has comprehensive performance like wear-resisting, corrosion resistance, shock absorption, which is better than other metal forming methods, such as forging, rolling, welding, punching, etc. So metal blanks produced by the method of casting process are still the most on the quantity and tonnage so far.
Forging
Forging is a metal processing process that using forging pressure machines to put pressure on metal blank,which will produce plastic deformation in order to obtain certain mechanical properties,a certain shape and dimensions. Forging can eliminate the as-cast loose defects that produced on metal smelting process,optimizing the microstructure, and meanwhile can preserve intact metal flow.So mechanical properties of forgings generally are better than that of the same material castings.
As one of the main metal processing process,applications of forgings are so wide.Such forgings are mostly used by people when safety factor is considered and good mechanical properties are needed.So forgings can be used in mining machinery(mining drill bits),agricultural machinery(agricultural wear parts),forestry machinery(mulcher hammer/teeth),automotive industry,trailer parts,ect. our photo gallery page can help you to learn more about forging applications.
