cdocastBuy the most advanced wire annealing furnace in the market, inquiry now!
CDOCAST wire annealing furnace is designed for continuous annealing of precious metal wire from 0.01-2mm. It combines resistance heating, protective gas, servo wire feeding, and water cooling to help jewelry and metal processing factories produce softer, cleaner, and brighter wire after drawing.
Use this section to help buyers understand why wire needs annealing after drawing, rolling, or cold working.
A wire annealing furnace is a continuous heat treatment machine used to soften metal wire, remove internal stress, improve ductility, and reduce breakage during further drawing, coiling, chain making, welding, or forming. For precious metal processing, it is often used as a gold wire annealing furnace, silver wire annealing furnace, copper wire annealing furnace, platinum wire annealing furnace, and bright wire annealing line.
Check the catalog for machine layout, technical reference, wire diameter range, and configuration details before requesting a quotation.
The machine is designed around stable wire movement, controlled heating, protective atmosphere, and fast cooling.
The wire feeding wheel controls movement speed so operators can match annealing time with wire diameter, material, and required softness.
The wire passes through the heating section where temperature can be adjusted for gold, silver, copper, platinum, and alloy wire.
The rear water cooling section helps cool heated wire quickly while the angled heating design reduces protective gas leakage.

0.01-2mm Feed Wire Diameter Range Inlet and feeding detail for fine precious metal wire, supporting 0.01-2mm gold, silver, copper, and platinum wire annealing.
Bright Wire Annealing Structure Machine structure for protective atmosphere annealing, stable temperature, and cleaner wire surface after drawing.
Annealing Process Before Chain Making Used with chain making production lines to soften wire before forming, reduce breakage, and improve chain making stability.For buyers who need a bright wire surface, atmosphere selection is one of the most important points.
The wire annealing furnace can work with argon or nitrogen for oxidation control. For brighter gold, silver, copper, and platinum wire, an optional ammonia dissociation system can decompose ammonia into nitrogen and hydrogen. Hydrogen helps create a reducing atmosphere, which improves wire brightness and reduces oxidation marks.
Keep these parameters clear in the inquiry so engineers can recommend the correct wire annealing furnace configuration.

Practical answers about wire diameter, annealing temperature, protective gas, bright surface treatment, cooling and production output.
The furnace is designed for continuous annealing of gold, silver, copper, platinum, palladium and compatible alloy wire. The appropriate temperature, feeding speed and protective atmosphere depend on the wire material, diameter and required surface finish.
The standard reference feeding range is approximately 0.01–2 mm. Very fine wire requires more precise feeding, lower tension and careful adjustment of the annealing speed. Please provide your minimum and maximum wire diameters when requesting a quotation.
Operators mainly adjust the heating temperature and wire feeding speed according to the material and diameter. Fine wire normally requires a lower speed and more careful tension control, while larger wire may require a different temperature and residence time. Final settings should be confirmed through production testing.
Argon or nitrogen can be used to reduce oxidation during annealing. The reference nitrogen consumption is approximately 2–3 L/min, although actual consumption depends on wire diameter, operating speed, gas sealing and the required surface brightness.
For brighter gold, silver, copper or platinum wire, the machine can be configured with an optional ammonia dissociation system. It generates a nitrogen-and-hydrogen atmosphere that helps reduce surface oxidation. Gas selection must follow the factory’s safety and ventilation requirements.
The standard reference maximum temperature is 1000°C. This is generally sufficient for common gold, silver, copper, platinum and alloy wire processes. The actual working temperature should be selected according to the alloy composition, wire diameter and required mechanical properties.
The angled structure helps connect the heating path with the rear cooling and sealing section. This design supports continuous wire movement, helps limit protective-gas leakage and reduces the chance of oxidation before the heated wire is cooled.
The heated wire passes into the rear water-cooling section. Clean cooling water should be used and maintained at a suitable temperature. Water condition, gas sealing and wire speed should be checked regularly to maintain stable surface quality.
After installing the feeding wheel, enter its measured diameter and width in the control interface according to the operating manual. Correct wheel data helps synchronize the displayed speed with the actual wire-feeding speed.
Output depends on the wire material, diameter, number of processing tubes, annealing temperature and feeding speed. Because fine wire normally runs more slowly, there is no single hourly capacity for all applications. Send CDOCAST the wire specifications and target output for a suitable configuration recommendation.
Yes. The continuous wire annealing furnace can be installed after wire drawing or rolling to relieve internal stress, restore ductility and reduce breakage before the next drawing pass, chain making, coiling, welding or forming operation.
Please provide the wire material, minimum and maximum diameter, expected production speed or hourly output, required surface brightness, available protective gas, factory voltage, cooling-water conditions and installation space. These details help determine the correct wire annealing furnace configuration.
1. An annealing furnace is usually capable of reaching higher temperatures to anneal metal. Depending on the needs of different precious metals, the stripping furnace can be heated to hundreds of degrees Celsius or even 1000°C.
2. The stripping furnace is usually equipped with a high-precision temperature control system to ensure that the temperature in the furnace is maintained within a stable and accurate range. This is crucial for the annealing process, because the physical properties and performance of metals vary significantly at different temperatures, and precise temperature control can ensure the consistency and effectiveness of metal annealing treatments.
3. The CDOCAST stripping furnace is equipped with an automated control system. Users can monitor and adjust parameters such as temperature, time and atmosphere through the touch screen. Automated control not only improves production efficiency, but also reduces errors and safety hazards in manual operations.
4. Modern stripping furnaces are usually designed to be easy-to-maintain structures. The heating elements and atmosphere control systems in the furnace can be easily inspected and replaced to ensure long-term stable operation of the equipment.
