The ball stud is a key component to ensure the stability of the car's handling, the ride comfort, comfort, safety, and the correct and accurate driving of the car. It is also called a ball hinge and a ball joint. During the driving process of the car, the ball stud needs to bear huge friction. For this reason, we often use high-frequency induction heating power supply to quench the ball stud to improve its hardness, wear resistance and service life.
After the ball stud is quenched by the high-frequency induction heating power supply, there will be a 2-3mm hardened layer on the surface, which greatly improves the hardness of the ball stud. As for how much equipment should be used for quenching heat treatment, this depends on the specific specifications of the ball stud.
The high-frequency induction heating power supply is produced by IGBT modules, with perfect functions and simple operation. When it performs quenching heat treatment on the ball stud, the quenching speed is very fast. Such a fast speed effectively avoids the phenomenon of oxidation and decarburization of the ball stud during the quenching process, and ensures the quenching quality of the ball stud. There is a thicker tough area under the hard layer on the surface of the ball stud pin, which has better compressive internal stress, which makes the fatigue resistance and breaking capacity of the workpiece higher, which meets its working requirements. What's even better is that the equipment will not generate noise and dust during the working process, which greatly improves the working environment of workers.
