Indutherm Sintering


For the production of multi-color rings in accordance with the diffusion bonding process, and bonding every kind of metal!

Sintering is the optimum process for producing multi-colored rings, mostly sold as wedding rings. Metals are processed under pressure and at temperatures below the solidification point. The pressure is generated pneumatically and not mechanically via a threaded spindle. This means that there is no risk of graphite parts breaking as a result of heat expansion. The fusion between layers has the same durability as the metal itself. Pre-manufactured rings can be easily resized (7 sizes and more).

Major Applications

  • With the sintering unit processes can take place under a vacuum, which is important for alloys with a manganese component
  • Processes can take place under inert gas
  • Straightforward installation/removal of the rings
  • Approximate duration of process: 5 minutes
  • Depending on the thickness of the rings, up to 6 rings can be processed simultaneously
