Induction Hardening Machine
Induction hardening process with induction heating is one method to increase the hardness of material surface. Duolin induction quenching equipment will heat up the workpiece surface rapidly to high temperature with high frequency(1-400Khz) induction power supply, cool down fast with cooling medium such as water and oil or other hardening liquid. The case hardening depth will decide the induction heating machine power and work frequency, high frequency induction power supply needed if customer need shallow case depth. If client required deeper depth, low frequency or medium frequency quenching induction power unit needed.
Induction Hardening Machine is a specialized piece of equipment used to surface-harden metal parts, enhancing their durability, wear resistance, and fatigue strength. This process involves rapidly heating the surface layer of the material using induction technology, followed by immediate quenching to create a hard, wear-resistant outer shell while maintaining a tough, ductile core.
Some parts will need induction tempering process to accomplish the induction heat treatment application depending on the requirements. Duolin engineer team can work out complete induction scan heating system. Duolin Induction heat treating furnace is also widely used for the surface or inner hardening of steel. With robot and CNC program induction scanner, Duolin can offer customer whole full automatically induction hardening and tempering production line, like rotate, lift, transfer. Duolin engineer teams have experience in variety of industries, such as oil&gas, aerospace, automotive and so on. Meanwhile, we also supply induction hardening equipment to heat treatment factory.
Duolin, founded in 1994, is a trusted manufacturer of induction heating machines and solutions, with over 20 years of industry experience. Offering equipment with power ranges from 4-2000KW and frequencies from 0.5-400KHz, all products are designed by Duolin's expert engineering team and produced under strict ISO9001:2015 standards. As a high-tech enterprise, Duolin holds more than 20 national patents, providing energy-efficient and reliable induction heating systems for industries worldwide.
Duolin's induction heating solutions are widely used for applications such as carbon steel hot forging, gear shaft hardening, long bar heat treatment, pipe heating for hot bending, and non-ferrous metal heating like aluminum and copper. Since expanding internationally in 2007, Duolin has established agents in countries like Brazil, Germany, and India, with end users in over 15 countries, some of whom have been partners since 2009.
Induction hardening application can be done in two different ways: single shot and scan hardening
Advantages of Induction hardening:
• No physical contact hardening
• Scan/ Stationary hardening
• Short time (a few seconds) hardening increase production and improve quality
• CNC or PLC Control heating and cooling during hardening
