Induction Annealing

What Is Induction Annealing 

Induction annealing is a process of controlled heating and cooling to soften metals.  In most annealing processes,  the metal is heated to an elevated temperature, held at temperature for a specified time and then allowed to cool slowly.  Annealing is commonly used to relieve internal stress caused by cold forming, hardening and welding and to increase the ductility of the metal.  It increases the machinability of the metal and it's ability to be further drawn, bent or formed.   One common use is to spot anneal hardened shafting to allow for subsequent machining operations.  Another common use is to anneal brass ammunition cartridges to prevent cracking when the bullet is inserted.

Why Magneforce Induction Annealing

Magneforce induction heating systems provide precise control of your annealing process.  The heating can be focused in specific locations,  maintaining the properties of surrounding areas.  Heating is identical cycle to cycle.  Using infrared sensors or attached thermocouples, parts can be brought to a set temperature and then held at temperature for an extended period of time.  Our HS5000R2TS touchscreen control heaters enable easy setup of customized temperatures profiles and can be configured with automatic scanners to selectively anneal multiple locations..

​

35 Years Experience

Magneforce has supplied thousands of induction heating systems since 1990 for brazing, soldering, annealing and many other applications.

Made In The USA

All Magneforce induction heating systems for annealing are manufactured at our facility in Warren, Ohio.

Custom Heating Coil Manufacturing

Proper heating coil design is essential to any induction annealing process.  Small changes in the coil can make the difference between good and bad parts.

 

We manufacture all heating coils in house, enabling rapid prototypes and the ability to refine the coil design and focus heating as required.

coil is designed to evenly

heat a 3" length of pipe

No Charge Sample Processing

We will process your sample parts and return them to you for evaluation.  All process parameters including heating power, heating time and temperature.  Setup pictures and/or videos will also be included.

The end of a stainless steel tube is heated and annealed for a subsequent crimping operation.

Induction Annealing Advantages

No Open Flame

The high temperature open flame of an oxyacetylene torch presents significant safety and fire hazards

Reduce Operator Skill Required

Heating with a torch requires a trained and experienced operator for consistency.  With induction heating, the operator just needs to load the parts into the fixture and hit the ON button.

A 12' length of hardened threaded shaft is annealed.  Heating is controlled and even over the length and is repeatable part to part.

Consistent Heating

Heating is the same cycle to cycle to assure that each annealed part will process the same as the one before.

Reduce Costs

Energy is only used when the system is actively heating.  No expensive oxygen and acetylene needed.

Induction Annealing Systems

We can supply basic, cost effective process fixtures and part nests to complete your process or complete systems ready to run .

                               HS2500R2C Pipe End Annealing System 

This system heats both ends of a double wall pipe in one operation.  The pipe is placed in the fixture and then the heating coils are slid into position.  The heating coils are configured to anneal both the internal pipe section and the external pipe section.

In House Development

When setting up an induction annealing system, our in house CNC machining & 3D printing capabilities enable fast turnaround on heating coils and processing fixtures.  We design and test the setup for your parts, fine tuning as needed to focus the heating as required for consistent annealing, part after part.
