This automatic sintering machine delivers high-pressure precision and thermal stability for superior bonding in jewelry and industrial applications.
Indutherm SU 450: Precision Diffusion Bonding & Sintering Systems
The Indutherm SU 450 series is the industry’s premier solution for the production of high-quality multi-color rings and bangles via the diffusion bonding process. By processing metals under precise pneumatic pressure at temperatures just below the solidus point, the SU 450 creates a molecular fusion between layers with the same structural durability as the metal itself. This pneumatic approach eliminates the mechanical risks associated with threaded spindles and thermal expansion, ensuring that pre-manufactured multi-color rings can be easily resized by 7 sizes or more without bond failure.
Highly Sensitive Reduction Control
The new SU 450 features a sophisticated sensor suite that monitors the material reduction in real-time to prevent over-deformation.
- Automatic Process Stop: Once a predefined reduction value (0.1 mm to 0.3 mm) is achieved, the system stops automatically to preserve ring geometry.
- Precision Temperature Regulation: Maintains temperature at critical levels until reduction begins, ensuring a perfect molecular bond every time.
- Pneumatic Pressure System: Generates pressure pneumatically, removing the risk of breaking graphite parts due to heat expansion.
- Vacuum & Inert Gas Capability: Essential for processing sensitive alloys, particularly those containing manganese or high-reactivity components.
High-Volume Production Ready
Designed for rapid cycles and digital integration, the SU series is built for modern jewelry manufacturing workflows.
- 5-Minute Process Cycles: Rapid bonding cycles allow for up to 10 sintering processes per hour.
- Multi-Ring Processing: Depending on thickness, up to 6 rings can be bonded simultaneously for maximum throughput.
- 100 Program Memory: Store and recall specialized recipes for various alloy combinations and ring dimensions via the LCD display.
- Data Connectivity: Standard RS 232, Ethernet, and USB interfaces with a built-in data printer for quality control and diagnostics.
