Mainly used for cobalt-chromium frameworks, cobalt-chromium crowns and bridges,TC4framework,TC4crowns and bridges, etc.3DRapid annealing process for additive metal materials. The equipment allows products to fully release residual stress during heat treatment, significantly improving toughness requirements; it also effectively ensures that products are not oxidized, simplifies the process, makes production safer, greatly saves labor and process costs, and improves production efficiency.
Technical Features
Rapid vacuum annealing design: Optimized heating and cooling rates specifically for mass production of dental prosthetics, shortening single-furnace process cycles and increasing daily throughput to meet the high-efficiency demands of dental processing centers.
High vacuum non-oxidizing environment: Ultimate vacuum can reach6.67×10-³ Pa and above, ensuring that cobalt-chromium alloy and titanium alloy are free of oxidation and discoloration throughout the annealing process. The surface of the workpiece is bright and clean, requiring no subsequent grinding or sandblasting.
Precise elimination of printing stress: Specifically forSLM/SLSThe complex reticular structure and thin-walled features of formed dentures are effectively relieved of residual stress generated by rapid solidification through precise vacuum annealing curves, preventing framework deformation or cracking.
Improve material toughness: After annealing, cobalt-chromium alloy,TC4The elongation and impact toughness of titanium alloys are significantly improved, meeting the mechanical reliability requirements for long-term wear of oral restorations.
IntelligentPIDTemperature Control System: Temperature control accuracy±1°C, supports multi-stage heating/Holding/cooling program, ensuring process consistency for each batch of dental prosthetics.
High-quality Heating Elements: Adopts high-temperature resistance wires or silicon carbide rods, with a maximum working temperature of up to1400°C, adapted for cobalt-chromium (approx.1100-1200°C) and titanium alloys (approx.800-900°C) different annealing temperature windows.
Compact Furnace Body Structure: The equipment occupies a small footprint, suitable for the layout of dental laboratories or small production workshops; the double-layer water-cooled casing ensures operational safety.
Fully automatic one-key operation:PLC+Touch screen control, automatically completes the entire process of vacuuming, heating, holding, and cooling, without the need for dedicated personnel, reducing reliance on operator skill.
Multiple Safety Protections: Over-temperature alarm, thermocouple break protection, overcurrent protection, water pressure interlock, vacuum interlock, etc., to ensure long-term stable operation of the equipment.
