The world’s fastest and most flexible horizontal hardening machine

The new HardLine Hybrid horizontal hardening machine combines a pusher and a continuous loading machine in one single unit–offering the best of both worlds.

The Horizontal Continuous (HC) and Horizontal Pusher (HP) versions are now combined in the new Horizontal Hybrid (HH) machine.  With EFD Induction’s unique modular system, the HardLine Hybrid can be used as either pusher, continuous or both–essentially providing three different functions in one machine, greatly reducing both cost and set-up time.


The HardLine horizontal heat treatment systems are field-proven solutions that deliver short cycle times, reproducibility and the reliability needed when mass-producing steel bars and shafts.


With the HardLine Hybrid, high scanning speed, quick loading/unloading systems and proven components work together to ensure high throughput rates. The machine, which is powered by an EFD Induction Sinac converter, can handle workpiece lengths from 50 to 600 millimetres and diameters of 5 to 50 millimetres. Automatic reject separation allows working without stops.


The HardLine Hybrid machine is very operator friendly with smart ergonomic design and easy-to-use control interfaces. It can be adapted to a new workpiece size, at the push of a button. Due to its numerous automatic systems, the set-up time is greatly reduced, taking only seconds to adjust.


 A single HardLine Hybrid machine can replace HC/HP systems and can therefore handle a wider range of workpiece dimensions and types, reducing the need for dedicated machines and requiring lower capital investment.
