Technical library
Four articles that answer real engineering questions completely, rather than stopping at the point where you would have to call someone. Written by people who build the machines.
We explain the principles behind machine selection and the questions that help us specify your system. Use these guides to prepare for a discussion about your component.
What is induction heating?
The physics, plainly. Eddy currents, the skin effect, the Curie point, and what an induction system is actually made of.
Frequency, power and case depth
Frequency decides where the energy goes. Power decides how fast. Time decides how far it spreads. Case depth is the result of all three.
Steels for induction hardening
C45, EN8, EN19, EN31, 4140, 4340 and 8620, plus cast irons. What hardens, what does not, and why prior condition matters more than people expect.
Induction versus furnace heating
Where induction genuinely wins, where a furnace is still the right engineering choice, and how flame and laser hardening compare.
Tell us about the part.
Send a drawing, the material, the case depth or temperature you need, and your production rate. Our engineers will help define the right machine for your process.
