Copper recycling and wire processing

Our fine and superfine wire drawing process utilizes either our recycled copper rod or CCA and involves drawing the wire to the desired final diameter. Whether using recycled copper rod or CCA, the drawing process entails multiple steps, including heat treating, annealing, baking, cooling, quenching and spooling, as may be necessary to achieve the desired wire diameter and other customer specifications. The CCA drawing process, however, is more complex than the process for using recycled copper rod, and utilizes our proprietary trade secrets to ensure that the wire maintains the original bimetallic bond from the raw material. The fine or superfine wire is either sold to customers or is coated and further processed to become magnet wire.

Our copper recycling pre-treatment phase utilizes our proprietary cleaning technology. We have applied for an invention patent on this process that involves manually or mechanically sorting, stripping, shredding and magnetically separating the scrap copper. The scrap copper is then compacted and pre-treated with numerous chemicals. Following the pre-treatment phase, the metal is smelted and fire-refined in a furnace. The furnace refining process commences with loading the furnace with the pre-treated metal, smelting it, and then refining and reducing it. Thereafter, the molten copper is continually belt cast and further treated, and the copper rod is ultimately wound into bundles for further processing or sale
