20KW Air Cooled IGBT Induction Heating Machine for Post-Weld Heat Treatment and Metal Processing

IGBT induction heating machine for heat treatment metals processing manufacturing (DSP-20KW)

Medium frequency induction heating is a safe and cost effective heating method, which improves the quality of installation or maintenance. this method is fast, simple and energy efficent, compared to conventional methods.medium frequency thechnology makes it easier and quicker to transfer effective enery in the workpiece. the quick-heater is a compact model.

this system is also clean and operates very quickly. the MF quick-heater saves you time as it can be deplogyed very repidly and heats faster and conventional methods, energy use is much lower thanks to its more efficient electricity consumption. each heater is customised to your needs and supplied with required size of inductors.

Applications

1.Mounting &dismounting :
mounting &dismounting of bearings,labyrinth rings, bearing inner rings, bearing rings, sleeves,couping gears ..

Shrink Fitting (Thermal Assembly):
Application: Heating gears, bearings, couplings, or rotors so they expand and can be easily slipped onto a shaft. As they cool, they create a tight, interference fit.
Bearing & Gear Removal (Disassembly):
Application: Quickly heating a seized bearing or gear to expand it for removal.
2. Welding & Construction Industry
This is one of the most common applications for portable air-cooled units, especially for field work where water is scarce.
Weld Preheating & Post-Weld Heat Treatment (PWHT):
Application: Preheating pipes, pressure vessels, and structural steel before welding to prevent cracking, and stress-relieving after welding.
Hydrogen Bake-Out:
Application: Heating welded areas to diffuse trapped hydrogen, preventing delayed cracking in high-strength steels.

3. Automotive & Manufacturing
In a production environment, air-cooled systems offer cleanliness and efficiency.
Brazing & Soldering:
Application: Joining metal parts (like AC compressor components, brake lines, or motor windings) using a filler metal.
4.Hot Forming & Straightening:
Application: Localized heating of metal bars or sheets to make them pliable for bending or straightening (e.g., correcting distorted shafts).
5.Aerospace & Energy
High-value industries that require strict process control and safety.
Composite Curing & Bonding:
Application: Curing adhesives and composite materials used in aircraft structures.
Turbine Blade Repair:
Application: Heating turbine blades for coating removal or repair brazing.
