Preheat Induction Heater

What Is Induction Pre-Heating?

Induction pre-heating is a process in which materials or workpieces are heated using electromagnetic induction prior to further processing. The purpose of pre-heating depends on the application:

· In the cable and wire industry, cable cores are pre-heated before insulation extrusion.
· Steel strips are pre-heated before pickling and zinc coating.
· Metals are softened via induction pre-heating to facilitate bending, and tubes or pipes are pre-heated in preparation for welding.
· Mobile induction pre-heating solutions enable onsite repairs of bearing assemblies.

Benefits of Induction Pre-Heating

· High energy efficiency: Rapid and precise heating reduces energy consumption.
· Short cycle times: Continuous and automatic control allows a single induction coil to handle a wide range of production requirements.
· Compact and versatile: Systems are easy to integrate into existing or planned production lines.

Industrial Applications

Induction pre-heating is widely employed across industries such as automotive, mechanical engineering, aeronautics, electrotechnical manufacturing, white goods production, and shipbuilding. One of the most common uses is pre-heating for welding operations, ensuring improved process efficiency and material quality.

This simple and cost-effective heating process provides fast and consistent heating for a variety of applications, including:

· Welding fabrication and construction
· Preheating of welds
· Post-weld heat treatment
· Coating removal
· Shrink-fit applications

Processes that traditionally required hours to achieve the desired temperature can now be completed in minutes using induction heating, significantly improving efficiency and reducing production time.

Induction vs. Other Heating Methods

	Induction Heating	Flame	Resistance
Reduce Injury	EXCEPTIONAL Only the part gets hot	POOR Open flame causes burns and exposure to toxic fumes	POOR Accidental touching can cause burns, broken pads can cause shocks
Reduce Labor	GOOD Fast setup/teardown No operator required during heating process	POOR Operator required to handle torch Often requires fire watch	POOR Slow and complex setup and teardown in many cases
Reduce Inefficiencies	GOOD Easy to self-perform Heating efficient with utility use	POOR Most heat is wasted into the air Inefficient with utility use	POOR Bad electrical power factor causes inefficient use of utility A lot of heat wasted in the process
Reduce Time to Heat	GOOD Heat is generated within base material Focused heat over the entire part speeds heating process	POOR Torch needs to be continually moved to heat entire part, resulting in slower heating speeds	POOR Heat is generated in the element instead of the part Unfocused heat results in slower heating speeds
