Originally designed and developed in the early 1970’s for the debinding and sintering of Tungsten Carbide materials with wax or PEG binder systems, the Sintervac AM takes this heritage and improves on the proprietary Sweepgas binder removal system offering a furnace that can debind in both partial pressures or positive pressures of Argon, Nitrogen, or Forming Gas depending on the customer’s choice of binders. The all‐graphite furnace hot zone offers a robust and inexpensive design for processing a variety of stainless steel, tool steel, mild steels and alloy materials. With a max temperature of 1,600 °C it can handle virtually all 3D printed metals on the market today.
In order to protect the hot zone insulation and elements, the Sintervac AM furnace comes with a tight all‐graphite retort or workbox inside the hot zone which is used to compartmentalize the process offgassing (that takes place in the case of debinding), directing it out of the furnace through a delube manifold plumbed out the bottom of the chamber using our proprietary Sweepgas debinding system. The use of a graphite retort allows the binder‐laden gases to exit the hot zone without passing across the heating elements or insulation pack, resulting in longer service life of the hot zone components. The Sintervac AM furnace line is available with an optional high‐vacuum pumping system and operates in a variety of processing environments including high/low vacuum and partial or positive pressures of Ar, N₂, and Forming Gas.
