Last week, I had a chance to visit KB company which mainly manufacture about Car elements and Car wheel. On occasionally, We have a chat about manufacturing process of wheel, I will discus with you about this topic. As you can see, the Car wheel is made of Sheet steel that is one of the most popular materials in this field. The manufacturing begin with punching. In this step, holes are punched in the sheet steel. In the next step, the sample will be formed to specify shape by pressing. Next, the wheel is continuous to be weld in order to join pieces of metal together permanently by melting the parts that touch. After the welding process, the car wheel will be transfer to polish surface also etching and painting. The final step of this process, the engineers will survey and check it again to certain it acts accurately and stably. All of steps must be certainly and precisely also follow the secure rules and technical requires.
