1, copper rod into the factory to transport, view and store most of China's cable companies with copper for outsourcing, should choose quality metal copper rods, standard supplier delivery, delivery procedures and guidelines, copper rod into the factory in accordance with GB/T 3048.2 or cable company Enterprise standard implementation. Copper rods can be stored in plastic sheeting or plastic film cover copper rods, that is, the most simple physical barrier method to block the copper rod and moist air touch.

Workshop with copper rods must be a copper rod coil for the naked eye to see if there is a black appearance, from the source of the control. 2, copper wire drawing Process Control the drawing of the 0.4mm monofilament is usually a series of annealed copper and pull machine, the need to pass the line, drawing and annealing, cooling, drying, and other processes. First of all, should choose the right mold, cut not too small, otherwise it will force the lattice variation of metal copper, aggravating the sharp rise in metal temperature. Second, check the ph of the emulsion before the boot, to ensure that the alkaline solution, together with the drawing oil should be increased antioxidant, in the copper conductor appearance constitutes a passive film, to avoid oxidation, when the line, adhere to the line tension stability, uniformity, not excessive trembling; in the process of drawing, the operator should ensure the proper water level, and ensure the degree of uniformity Avoid annealing lack or excessive annealing, the copper conductor appearance should not have the remaining liquid, can be placed in front of the line a monotonous felt (often replaced), to ensure the monotony of monofilament.　　

　　 After all, in the drawing after the disc with a bright plastic film sealed, stored in a monotonous environment alongside, to be circulated, otherwise it will be because of the high temperature of the conductor surface and easy and humid air attack the risk of oxidation. 3, copper wire stranding (twisted) and insulating rubber, sheath rubber extrusion process with copper wire stranding for example, conductor in the process of stranding, through each road press mold to make the metal crystal lattice alteration structure, under strong external forces, after the die copper conductor temperature than die before the larger travel, so the copper conductor outer layer is easy to oxidize. It can be used in the cutter and the process of infusion hose will antioxidant (0.3% of benzene and triazole alcohol solution) into the copper wire, drip standard to just moist copper wire appearance, to avoid too little there is some oxidation or excessive waste of the appearance of attack, in all the preparation for safe oxidation, and then boot work. The receiving line should ensure that the receiving coil is monotonous, the receiving line is full, and the plastic film is sealed.
