Bonding involves connecting metal or materials containing metal to materials such as plastic, rubber or thermoplastic materials without using a bonding adhesive. Bonding with induction entails accelerating the polymerization of an adhesive by heating the metal parts to be joined. The required temperature range is generally from 150 ºC to 220 °C. Accurate heat control is critical to successfully bonding with induction heating. 

Check out the latest application video from THE LAB at Ambrell. The videos shows though-hardening of a cutting tool with an Ambrell EASYHEAT^TM induction heating system along with an optical pyrometer to measure temperature:

A client was introducing a new product line to the market and needed to heat magnetic steel parts, which would become cutting tools, for forging. The parts were knife blades and shears, and they needed a fast, repeatable heating process they could count on in production. Their objective was for each part to be heated in under seven seconds to 2150 ºF (1177 ºC). 

An engineering firm had a new process that required the removal of a coating of insulation. It was important not to heat the material up too much, as the tin-coated copper might then melt. They turned to THE LAB at Ambrell to develop a solution that met these requirements.
