What Is An Induction Heating Machine?

Fast, Precise & Repeatable Non-Contact Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel — or a semiconductor such as silicon carbide, carbon or graphite.

Induction heating machines heat metal parts quickly and accurately through electromagnetic induction. Compared with flame or resistance heating, they provide higher efficiency, better temperature control and improved process consistency.

They are widely used in forging, hardening, brazing, annealing, quenching and heat treatment operations across automotive, machinery, fastener and metal processing industries.

Our Capabilities

Six Solution Lines, One Engineering Standard

VOLTAHEAT induction heating systems
01 — Heating Systems

Induction Heating Systems

Induction heaters use electromagnetic induction to efficiently and quickly heat metals and other conductive materials. This non-contact method delivers precise temperature control and uniform heating — ideal for hardening, brazing, forging and heat treating. VOLTAHEAT offers output power from 10 kW to 300 kW and frequency from 1 kHz to 1 MHz, plus customized induction coils for your unique application.

Handheld induction brazing machine
02 — Brazing & Welding

Induction Brazing & Welding Machines

Induction brazing joins two or more materials using a filler metal with a lower melting point than the base materials. An alternating current in the coil generates an electromagnetic field that rapidly heats the joint area, enabling precise and efficient joining. Handheld induction brazing machines offer selective heating, improved joint quality, reduced oxidation and consistent results — at lab bench or on the production floor.

FAQ

Frequently Asked Questions

Induction heating is suitable for conductive materials such as steel, stainless steel, copper, brass, aluminum and carbide materials.

The required power depends on workpiece size, material, target temperature, heating time and production capacity.

High frequency is often used for shallow heating, brazing and surface hardening. Medium frequency is more suitable for deeper heating, forging and larger workpieces.

Yes. VOLTAHEAT can design customized induction coils according to the shape, size and heating area of the workpiece.
