Overview

Induction heat is used for preheating bolt heads prior to forming bolt and screw heads, lips on plates, hollow parts, fabrication of nuts from a titanium, inconel (nickel alloy) or stainless steel slug. Slug is forged to create hole then it is treaded. Among the benefits induction heating delivers to hot forming, hot heading and forging processes:

Benefits

• elimination of springback effect
• low pressure and minimal residual part stress
• better grain flow and microstructure
• reduced need for post production tempering and heat treating
• extension of die life
• direct application of heat in the billet or work piece with precision and consistency
