HardLine Horizontal Heat Treatment Machines – HC / HP / HH Series

1

ENRX HardLine horizontal heat treatment systems deliver fast, reliable and repeatable hardening for steel bars and shafts. The product range includes:

  • • HardLine Hybrid (HH 600) – A dual-function system combining both the pusher (HP) and continuous (HC) machines in one modular solution, capable of handling workpieces 50–600 mm long and 5–50 mm diameter. Automatic configuration via stepper motors enables fast changeovers.
  • • HardLine Continuous (HC 300 / HC 600) – High-speed continuous hardening machines with throughput up to 10 m/min. Ideal for production lines, featuring enclosed heating/quenching areas, automatic reject separation, and adjustable conveyor systems.
  • • HardLine Pusher (HP 600 / HP 1200) – High-precision hardening systems for shafts up to 600 or 1200 mm long and 5–50 mm diameter. Twin pusher versions double productivity. Includes CNC-controlled servo feed and robust rotation units.

All HardLine systems are powered by ENRX Induction SINAC converters and use advanced controls including 15” TFT touchscreens, ProfiNET, IO-Link sensors, high-speed edge detection (1 μs response), and multilingual interfaces.

  • • Modular dual-machine architecture (HC + HP) in the Hybrid model
  • • Fast setup with automatic configuration using stored recipes
  • • High throughput: up to 10 m/min on HC systems
  • • CNC-controlled servo-motor feed on HP machines
  • • Automatic reject separation for uninterrupted production
  • • Enclosed heating & quenching sections for safety and cleanliness
  • • 15” TFT touch-screen control terminal with real-time diagnostics
  • • ProfiNET & IO-Link for advanced automation and sensor integration
  • • Optional coil-protection with ground-fault detection
  • • Robot-compatible architecture
  • • Lower capital investment with modular dual-function Hybrid machines
  • • Faster changeovers and reduced downtime due to automation
  • • High productivity and process stability
  • • Improved ergonomics and operator accessibility
  • • Consistent hardness profiles thanks to high-accuracy sensors
  • • Reduced maintenance and higher equipment uptime
  • • Seamless integration into production lines
