This process is used to harden also large parts and complex geometries. Inductive, flame, or laser heating raises the temperature on the workpiece's targeted zones that are then quenched once they reach the required hardening level. The surface hardening of large workpieces relies heavily on the knowhow and qualifications of our employees, and they were instrumental in establishing the reputation of Härterei Reese as a particularly quality conscious and customer oriented company. Many years of experience have culminated in optimised processes and component based solutions for both flame and inductive hardening.
A high level of reproducibility can be obtained with the targeted definition of machine parameters. Hence, in many cases, surface hardening presents itself as a technical and economical alternative to conventional case hardening. The installations at Härterei Reese allow surface hardening on workpieces up to 16 t in weight and 10 m in length. Induction coils are available for many standard workpieces, accelerating greatly the fulfilment of these orders.
