Additive Manufacturing, 3D-Printing Additive manufacturing allows for the direct conversion of design construction files fully functional objects. With 3D-printing objects from metals, plastics, ceramics, glass, sand or other materials are built-up in layers until they have reached their final shape. Depending on the material, the layers are interconnected by means of a binder system or by laser technology. In most cases, these objects must be heat treated after printing. Nabertherm offers solutions from curing for conservation of the green strength up to vacuum furnaces in which the...

Plastics Tempering, Curing, Vulcanization and Degassing of Plastics, Rubber, Silicone, and Fiber Composite Materials Many plastics and fiber composite materials must be heat-treated for product improvement or to ensure that they have the required product properties. In most cases, chamber dryers or furnaces with air circulation are used for the respective process. The following examples outline the processes which these furnaces can perform. PTFE (polytetrafluoroethylene) One application is the heat treatment of PTFE. This process can be used to improve the adhesive properties, the mixture...

Brazing, Forming The furnaces shown in this catalog can be used for various heat treatment processes. Nabertherm has developed interesting solutions for the processes described below as examples: Brazing In general, when speaking of brazing we have to distinguish between soft-soldering, brazing and high-temperature brazing. This involves a thermal process for forming substance-to-substance bonds and material coatings during which a liquid phase is generated by the melting of the solder. Based on their melting temperatures, the solder processes are classified as follows: Soft-solders: Tliq <...

Retort Furnaces Retort furnace VHT 500/22-GR H2 with CFC-process box and extension package for operation under hydrogen 11

Hot-Wall Retort Furnaces up to 1100 °C Retort furnace NRA 25/06 with gas supply system Retort furnace NRA 150/09 with automatic gas injection and process control H3700 These gas tight retort furnaces are equipped with direct or indirect heating depending on temperature. They are perfectly suited for various heat treatment processes requiring a defined protective or a reaction gas atmosphere. These compact models can also be laid out for heat treatment under vacuum up to 600 °C. The furnace chamber consists of a gas tight retort with water cooling around the door to protect the special...
