Efficient and precise heating required
To improve production rates and fastener quality, fastener manufacturers use heat in their heading, threading and patching production processes. With induction heating, fasteners are heated quickly, efficiently, and with maximum repeatability.
Advantage of IH
- A rapid heating method for improved productivity and higher volumes
- Precise, even heating of all, or part, of the fastener
- A clean, non-contact method of heating
- Safe and reliable; instant on, instant off heating
- Cost effective, reduces energy consumption compared to other heating methods
- Easy to integrate with remote workheads
Pre-heat for forging
IH is commonly used for preheating bolt and screw heads prior to forging. IH heating offers many benefits for the warm or hot heading process. Pre-heating eliminates the springback effect for higher quality parts. It also enables forging at relatively low pressure and small residual stress.
The heading process yields better particle flow and microstructure that reduces the mechanical properties of the part and the need for tempering and heat treatment after fabrication.
This improves yields and greatly increases productivity.
