The ball stud is mainly composed of end cover, ball pin, ball seat and dust cover, etc. It is a key component to ensure the stability of the car's handling, ride comfort, safety, and the correct and accurate driving of the car. Also known as ball hinge, ball joint. The working environment of ball studs is very harsh, so we have very high quality requirements for ball studs.
There are many factors that affect the quality of ball studs. For our industry, quenching is the most important. Our Brazilian customer uses an ultra-audio frequency induction hardening machine to quench the ball stud. According to him, the quenching effect is very good. The quenched ball stud has high hardness, wear resistance, good plasticity and toughness, which meets the requirements of meet its performance requirements.
At the beginning, when our Brazilian customer sent us an inquiry, he attached his ball stud drawing. After seeing the drawing, our technicians understood that the customer required the quenching depth of the ball stud to be 2mm. According to its specification , soon recommended our 60kw super audio frequency induction hardening machine for him. After communication and exchange, cooperation was finally reached.
While providing the customer with a super audio frequency induction hardening machine, we also made two profiling inductors for him according to the specifications of the customer's ball pin. Using this inductor for quenching, the entire quenched surface of the ball pin can be induction heated at the same time. After reaching the quenching temperature, the inductor sprays water to cool itself. This quenching method not only improves production efficiency, but also ensures quality.
