What Benefits Does Induction Annealing Offer?
Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy
Increases production rates with faster heating cycles
Reduces defect rates with repeatable, reliable heat
Eliminates variability from operator-to-operator, shift-to-shift
Maintains metallurgical characteristics of the individual metals
Annealing with induction required 45 seconds to heat the tube to the target temperature. This application met the client's objective
Induction annealing offers the same result every time, which makes it ideal for a high volume process such as this one. The previous oxidation issue forced them to polish the handles which added a step in their manufacturing process.
The client wants to anneal a stainless steel tube while avoiding oxidation. Induction annealing offers the same result every time, copper tubes of various geometries heated to temperature in a matter of seconds, which makes it ideal for a high volume process such as this one.
The ammunition industry has been annealing with inefficient methods which require much floor space, lack consistency, create excess inventory carry costs, and don't permit in-process inspections. Induction annealing ensures each and every case is quality annealed, reducing variation and damage typically found in mass annealing processes.
Annealing with induction heated the client's parts to the desired temperature in less than three seconds. Their previously-used gas oven required twice as much heating time as the induction heating process. Induction annealing is more energy-efficient and requires less space compared to a gas oven.
Looking to replace an inefficient oven process, a stainless steel tube is heated in just 30 seconds, improving efficiency for this application. A custom-designed single position multi-turn helical coil was built to generate the required heating for this induction annealing application
The client wanted to be able to anneal parts of various sizes, which was achieved with a concentrator coil. Induction annealing is a new process for the client, and Ambrell's lab expertise proved very valuable when creating the process...
Induction annealing achieved the targeted steel wire temperature within three seconds. Ambrell performed a free laboratory test, designed a cost efficient, in-house process and connected them with an automation partner to maximize productivity. The client now has better control over their end product.
Our client had a requirement to anneal large quantities of work-hardened stainless steel crowns. Induction was suggested for its precise, controllable heating. Since oxidation is unacceptable in the finished dental product, induction heating is the appropriate choice for heating in an inert atmosphere.
To anneal brass tubes into handrails, a twelve-turn helical coil was used to heat an 8”x3” (20.3cm x 7.6cm) area above the end of the tubes. Each of the four tubes require a different heat cycle and time to reach the required temperature.

About Induction 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 it can be a semiconductor such as silicon carbide, carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
