Induction Bolt Heating Machine

About Induction Bolt Heating Machine

What isbolt heating machine?

Expanding bolts with induction is the proven time- and labour-saving alternative to inefficient flame and resistance heating. With induction, a specially designed coil is inserted into the turbine bolt. Rapid, precisely controlled and localized heat is then induced directly in the bolt. The heat expands the bolt by an exact, pre-decided length, making it easy to remove the nut.

What are the benefits

Foster Inductionheat spreading is very accurate, due to the heat being generated within the component, you only heat the part you want to heat, and thus the bolt threads with nuts stay cold during the heating operation.
The heating process is very fast and accurate there simply isnt enough time for heat to travel into the thread area. And with induction there is no risk of rods melting inside the bolts.

In the bolt expansion process, focus on safetyis vital for a consistent result and for avoiding damage to either personnel or the expansion bolt itself. It is very safe and easy method to heat power turbine nut bolt.

Its precise and localized heat is faster and saferthan resistance and flame heating process.

Compact induction:
You can move it around a workshop or factory floor.
Flexible:It can be fitted with various coils for various bolt dimensions. Induction coils can be changed in seconds.

Reduced costs: Fasterheat delivery, reduce the heating expenses compared to flame based high cost heating methods.

Improved quality:Precise repeatability of heating cycles is assured. The same amount of energy is applied to each bolt. A constant energy level and heating time is guaranteed.

Eco-friendly:No flames, no gas and virtually no radiant heat means a more comfortable, more productive working environment. Save energy-save environment.
