4 Meter Vertical Complete Induction Hardening System For Pin 

Induction heating for hardening is one kind of application for induction heating, induction quenching system is common for shaft, pin, gear, brake, wheel, pulley and other auto parts. Because fast heating and energy saving of IGBT induction heating technology, more and more customer choose induction heating as their first choice.

Duolin made complete CNC induction hardening system for customer in South Africa, including 250KW low frequency induction quenching heater, 3500Kva transformer, cooling system and 17 set of heating coils with cooling coils to cover pin diameter range 60-200mm, pin maximum length to 4 meter.

After testing in our factory for sample parts, the hardening result reach to 4mm 54HRC, customer satisfied with the result and the complete system working. And they knew that the hardening result can be adjusted by the output power, heating time, cooling time, cooling capacity on CNC program setting.

Any inquiry for metal parts induction surface hardening, contact us freely, our engineer team will offer you free solution and testing to choose the correct induction heating machine power and work frequency.
