The distinction between forged wheel and cast wheel is mainly distinguished from its technological characteristics and its own characteristics.The advantages of forged wheels are: high strength, light weight, fuel saving compared to cast wheels, but due to the level of technology and cost considerations, its shape can not be very complex.The casting heel weighs much more for the same volume, and because it is a mold production and casting, its shape is more variable and can be made very complex.Be careful when buying replacement wheels. Check each wheel carefully.

　　1. A simple way is to find a metal stick and knock twice along the entire wheel and spokes to hear whether the sound is crisp and continuous. If there is noise, it is likely tohave internal injuries or impurities.

　　2, if you have the conditions, you can also do professional ultrasonic testing to see if there is internal injury or shadow, because it may be the internal structure of the problem.

　　3, before the tire can also do a dynamic balance, beat a circular beat.Good wheel manufacturing process is high, direct dynamic balance should be no problem, if the dynamic balance, circumferential beat of these two is not qualified, then the quality of the wheel is very poor.

　　Casting: the process of melting the metal into a liquid that meets certain requirements and pouring it into the casting mold. After cooling, solidification and cleaning, the casting (parts or blanks) with predetermined shape, size and performance is obtained.

　　Forging: using forging machinery to apply pressure to the metal billet, so that it produces plastic deformation to obtain a certain mechanical properties, a certain shape and size of the forging processing method.

　　Through forging can eliminate the loose cast metal, welding holes, casting is a relatively old process in China (such as bronze, etc.), the mechanical properties of cast parts are generally not as good as forged parts, so the cost of forging wheel is the highest, so it is also the best.
