KNC/V+KLV hardening line for treatment of aluminium castings up to 600 °C

Be self-sufficient and avoid expensive and protracted co-operations

The semi-automatic hardening line is a combination of two facilities—a furnace and a cooling bath with cooling in water, oil, or a mix of water and polymer. It’s controlled by a programmable PLC that corrects the course of the temperature curve and the temperature of the water in the bath and synchronises the motion of the furnace and the door and the loading of the charge basket. The line thus places a minimum of demands on the operator.

The time needed for charge transport from the start of door opening until complete submersion of the charge is a mere 15 seconds. Additionally, thanks to its thoughtful design, this furnace is easy to service, and its layout can also be adjusted without major problems.

The greatest advantage, however, undeniably lies in what our line can help you to save. Ask us for a calculation of return on investment, and we will show you that having an LAC line for processing aluminium castings pays off.

  • furnace for heat treatment
  • electrical furnace carriage
  • hydraulically controlled door opening towards the back
  • Simatic S7-1200 PLC with operator panel
  • “N” type control thermocouple
  • furnace limit unit

Optional accessories available at additional cost          

  • furnace for artificial ageing
  • ammeters for checking the status of heating elements
