The protective gas furnace  LCA 04/13 LB with annealing bell is ideal for stress-relief annealing after laser sintering and is very easy to operate.

With its compact design, this furnace fits in any room. The batch to be annealed is placed under a special annealing bell. The protective gas flow is set via the integrated gas-feeding system in the front of the furnace. The lifting table can be used for rapid cooling - either automatically according to the program or manually, depending on the process.

Key Facts

  • MyNabertherm App for online monitoring of the process on mobile devices for free download
    Defined application within the constraints of the operating instructions

Additional equipment

Required accessories

Annealing bell set including:

  • Annealing bell
  • Annealing disc
  • Base plate with gas distribution slots

Because it is a combi furnace, the same model can also be equipped with a corresponding sintering bell set for sintering cobalt-chromium.
