Indutherm SU 450 Automatic Sintering Machine

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

*Note: These items are heavy, and require a freight truck to be delivered. A customer service representative will contact you about your order.

Our efficient solution for ring and bangle production

The new SU 450 features a highly sensitive sensor system that continuously monitors the reduction of rings, providing real-time updates on reduction values via the display. The temperature is automatically regulated with precision, maintaining it close to the solidus temperature until the reduction begins. Once the predefined reduction value is achieved (ranging from 0.1 mm to 0.3 mm, depending on the composition and alloy), the process stops automatically, preventing excessive deformation.
