CDOCAST Advanced Precious Metal Annealing Furnaces

Annealing precious metals requires a perfect balance of temperature control, atmospheric purity, and operational efficiency. CDOCAST annealing furnaces are engineered to deliver precisely that. Designed specifically for the annealing of gold, silver, platinum, and other precious metals, our furnaces integrate innovative technology to ensure superior results in every cycle.

• Advanced Heating Technology for Uniform Results

At the core of the CDOCAST annealing furnace is a high-temperature resistance wire heating system. This technology enables exceptional temperature distribution across the heating chamber, eliminating hot spots and ensuring consistent annealing. With fully programmable controls, users can tailor the heating process to specific material requirements, achieving optimal ductility and material integrity.

• Rapid Cooling and Protective Atmosphere

The integrated cooling water tank allows workpieces to be rapidly cooled after heating, significantly reducing processing time while preserving metallurgical characteristics. Moreover, the furnace supports inert gas environments, such as nitrogen, to prevent oxidation during annealing. This ensures that precious metals retain their luster and purity, free from tarnish or surface degradation.

• Ammonia Decomposition Option for Enhanced Efficiency

For customers seeking additional flexibility and cost savings, CDOCAST offers an optional ammonia heating and decomposition device. When heated, ammonia breaks down into nitrogen and hydrogen, creating a reducing atmosphere that enhances workpiece brightness. This solution not only improves visual quality but also lowers operational costs, making it an ideal choice for high-volume applications.

• Robust Design and Smart Safety Features

Constructed from high-grade stainless steel, the heating chamber combines durability with exceptional heat resistance. A specially designed combustion device at the furnace entrance actively prevents oxygen ingress, maintaining an oxygen-free environment throughout the annealing process. This critical feature safeguards against oxidation, ensuring flawless results batch after batch.

• Streamlined Workflow for Maximum Productivity

The CDOCAST furnace simplifies operation with its user-friendly design. Once annealing is complete, the loaded metal rack can be effortlessly pushed and rotated, allowing workpieces to descend directly into the cooling pool for immediate quenching. The annealed components are then easily retrieved, ready for the next production stage. This seamless workflow minimizes handling time and maximizes throughput.

• Ideal for Modern Precious Metal Processing

Whether you are crafting jewelry, producing industrial components, or refining high-purity materials, CDOCAST annealing furnaces offer the reliability and precision demanded by today’s competitive markets. By combining advanced heating, atmospheric control, and operational simplicity, our furnaces help manufacturers achieve higher quality outcomes while reducing energy consumption and costs.
