An INDUCTION END HEATING MACHINE is a type of induction heating system used to heat the end portion of metal bars, rods, pipes, or billets before forging, upsetting, bending, threading, or other manufacturing operations.

How it works

The machine uses the principle of Electromagnetic Induction:

1. An alternating current flows through a copper induction coil.
2. The coil generates a rapidly changing magnetic field.
3. When a metal workpiece is placed inside or near the coil, electrical currents (eddy currents) are induced in the metal.
4. These currents generate heat directly within the metal, causing the end section to heat quickly and uniformly.

Common applications

• Forging bolt heads and fasteners
• Heating bar ends for upsetting operations
• Pipe end forming
• Shaft and axle manufacturing
• Automotive component production
• Steel and non-ferrous metal processing

Advantages

• Fast heating (often within seconds)
• Energy efficient
• Precise heating of only the required end section
• Clean process with no open flame
• Consistent temperature control
• Reduced oxidation and scale formation

Typical temperature range

Depending on the material and process:

• 600–900°C for bending and forming
• 1,000–1,250°C for hot forging
• Up to about 1,300°C for some steel applications
