Nabertherm offers optimised furnaces for Metal Injection Moulding
August 21, 2023
Nabertherm GmbH, headquartered in Bremen, Germany, offers an extensive range of furnaces for the heat treatment of metals, including debinding and sintering furnaces used in Metal Injection Moulding. The company recently optimised its product line and has revised the specifications for its furnaces, publishing a new product catalogue focusing specifically on MIM applications.
For the thermal or catalytic debinding of MIM components, Nabertherm offers a gas-tight hot-wall retort furnace under its NR product line. This range includes models specially developed for catalytic debinding of ceramic and metal parts, as well as furnaces operating under hydrogen.
For the MIM sintering stage, Nabertherm recommends its VHT range of furnaces. Due to the high sintering temperatures, this process step usually takes place in a cold-wall retort furnace. Nabertherm offers a selection of standard sizes from the VHT product line from 40-320 litres.
The furnaces are specifically adapted to the material used. For the sintering of stainless steels under a hydrogen atmosphere, for example, furnaces with heaters and insulation made of molybdenum and heating bands made of tungsten are used. Furnaces with graphite heaters and graphite felt insulation are ideal for steels that can be sintered in a non-reducing process gas atmosphere.
To improve workflow, Nabertherm offers four models of thermal/catalytic debinding furnaces that are sized to match those used for sintering. This enables the direct transfer of the batch from the debinding furnace to the sintering furnace. The company’s seventy-strong engineering team can also develop tailored solutions for customers.
Nabertherm will present a complete overview of its optimised range of furnaces for MIM applications at this year’s Formnext event in Frankfurt, Germany.
