How to distinguish forged wheels from cast wheels

Issuing time:2022-02-20 15:33

The distinction between forged wheel and cast wheel is mainly distinguished from its technological characteristics and its own characteristics. Forged wheel has the advantages of high strength, light weight and fuel saving relative to casting wheel, but due to the technological level and cost considerations, its shape can not be very complex. The casting wheel has a lot of weight under the same volume, and because it is mold production and casting, its shape is more variable and can be done very complex. Buy replacement wheel must pay attention to, each hub should be carefully checked.  

1, the simple way is to first find a metal stick, along the whole hub and spokes knock two rounds, listen to whether the sound is crisp and continuous, there is likely to be noise inside the internal injury 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, the direct dynamic balance should be no problem, if the dynamic balance, the circumference of the two have a failure, 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.
