How to distinguish forging hub, casting wheel hub?
Further, because the forging wheel structure, can bear high stress, so in the design, it can design some of the more lively thin spokes, freedom of design is higher but relatively, but the price is casting forging wheel hub is much higher, which are basically used in pay attention to control on high-end cars. The high performance super run, all without exception is used. In case of forged wheels Tiida 08 years, has produced a version of the sport, with the NISMO (Nissan's refit factory) 16 inch forged aluminum wheels, a price of 2500 yuan! The original 16 inch Sylphy cast aluminum wheels for 600 yuan / month, the difference is big, remarkable
Both the production and processing methods are different, so the characteristics of the use is also quite different:Casting type rim is aluminum water melting casting in sand mold, the cooling molding after machining (burr trimming, appearance, polishing) is made; and it is the use of forged steel mold, will soften the aluminum block arranged therein, with the punching method to the type. Stay cool, then made by machining. Casting and forging to mass production, because the procedure is complicated, so the production cost is relatively high, but the forging hub in the production process for aluminum block after continuous stamping, so after forming, its molecular structure will become very close, so it can withstand high pressure, thus in the same size under the same strength, forging wheels are also lighter than casting wheel.
The back of the casting is concave, the forging is flat, the following figure 57s and te37 experience, not necessarily, for reference only, then there are SSF spinning, casting process, also said
