Frequently asked questions about sintering furnaces

A sintering furnace is a special furnace that generates high temperatures to join materials through sintering processes without them melting completely. This technology is used in various industries, such as ceramics manufacturing, technical ceramics, dentistry and metal processing.

The sintering process is carried out by heating powders or materials to just below their melting point. This causes the particles to bond and a solid material is formed. The sintering oven precisely controls the temperature and time to achieve the desired degree of sintering, which is crucial for many production processes.

Sintering furnaces are used in various industries, including:

  • Ceramics: High-temperature sintering for technical and decorative ceramics.
  • Dentistry: production of dental prostheses from sintered zirconium oxide.
  • Additive manufacturing: Sintering of metal and ceramic powders in 3D printing technology.
  • Metallurgy: Powder metallurgy for the production of complex components.

A sintering oven is not suitable for materials that require a complete melting process. In addition, some plastics or organic materials that need to be processed at lower temperatures cannot be sintered efficiently. Conventional melting or pressing processes are more suitable for these materials.
