Sintering / Diffusion Bonding | SU-series

Sintering/Diffusion Bonding

Sintering is the optimal process for producing multi-coloured rings, mostly sold as wedding rings. Metals are processed under pressure and at temperatures below the solidification point. The fusion between layers has the same durability as the metal itself. Pre-manufactured rings can be easily resized.

Indutherm offers two methods of sintering:

The sintering kit for installation into existing casting machines or special sintering machines, the SU series.

SU 450

The new SU 450 is equipped with a highly sensitive sensor system, which permanently controls the reduction of the rings and provides real-time information about the reduction values on the display. The temperature is regulated automatically and very precisely close to the solidus temperature, exactly until the reduction begins. As soon as the pre-defined reduction value has been reached, the process stops automatically and so too much deformation can be eliminated (depending on composition and alloy the pre-defined reduction value lies between 0.1 mm and 0.3 mm).

Benefits:

  • program control for 100 different process cycles
  • LCD display
  • sensor control system for permanent process control
  • real-time display of the reduction
  • no long-winded preliminary tests
    less finishing effort and loss of metal

SU300

SU 300

Die SU 300 eignet sich für durchschnittliche Produktionsaufkommen und ist eine speziell zum Diffusionsschweißen gebaute Anlage für die gut ausgestattete Trauringfabrik. Sie sichert eine exzellente Qualität von Bi- oder Multi-Color-Trauringen.

Vorteile:

  • Sinterprozess kann unter Vakuum erfolgen, wichtig bei Legierungen mit Mangan-Anteil
  • Sinterprozess kann unter Schutzgas-Atmosphäre erfolgen
  • Einfaches Bestücken und Entnehmen der Teile
  • Prozessdauer ca. 5 min.
  • Je nach Dicke der Ringe sind bis zu 6 Ringe in einem Prozess zu bearbeiten.
