POST-INDUCTION TEMPERING OF CV JOINTS

The Constant Velocity Joint is one of the most successful examples of high speed convection tempering. With 9 systems installed with three global CV Joint manufacturers, acceptance of soak time elimination is now past tense. One manufacturer replaced a 90-minute batch temper (200 parts in-process) with a 10-minute continuous tempering process (20 parts in-process).

Another replaced their in-line induction tempering process with an in-line 20-minute continuous high speed convection temper, by eliminating the bottleneck of their 40+ second induction tempering process they were able to nearly double the line throughput. An amazing return for such a modest capital investment.
