( copper ) wire, cable production process mainly includes the following several steps:1 wire filament (that is, a very fine copper wire is wound into a copper wire ):The 2 insulating wire core extrusion ( through the extruder with PVC plastic copper wire wrapped into the insulated conductors ): extrusion?3 spark experiment ( used to test 2 step out of the line to see if there is any breakage. ):4 wire, a disc (that is, 2 steps of extrusion of the insulated wire wound on the plate storage ):The 5 extruded sheath ( is through the extruder with PVC plastic 2 / 3 insulated wire wrapped into cable ): extrusionThe above is a wire production process, well after the need to wire, connected with the plug into the plug line, concrete steps are as follows:1 wire (that is, a stripped of a PVC sheath ):2 ( bracket ) riveting (that is, head and sheet metal of the plug by machine pressure, connected together ):3 Baptist tin ( some thread needs in tin water dip, in order to ensure thread copper not scattered ):4 plug injection: plug injection?The 5 power-on test ( test plugs and wires are conducting good ):The 6 amendment ( wrapped with scissors to cut together with thread, ribbon tied ):7: Packing PackagingA 6 cutting ( 5 steps in the cable according to the length requirements into a section of the section ): LZ给分吧
