Product Overview

This series of jewelry bright annealing furnaces is specifically designed to address the oxidation and material loss challenges in high-end jewelry manufacturing. Using a precision-sealed stainless steel muffle tank combined with high-vacuum systems and protective atmospheres (H₂/Ar/N₂), the furnace provides bright annealing up to 950°C. It effectively eliminates casting or processing stresses while ensuring extreme surface purity.

Key Application Values

• Zero Oxidation Loss: Operating in an absolute protective environment prevents the formation of oxide layers, maximizing the protection of precious metal weight.
• Perfect Color Retention: Annealed gold and silver jewelry maintain their original mirror-bright finish and natural color, allowing for direct transition to setting or testing.
• Extreme Control Accuracy: ±0.1°C precision prevents risks of deformation or melting caused by temperature fluctuations.
• Clean Production: Dust-free design and high-quality seals ensure no impurities are introduced, meeting the requirements of high-end luxury goods.
