According to the different uses and diameters of the wire rope, the core rope is generally made of steel wire rope with a diameter of 3.5-4.9mm and 61-133 strands. The traditional wire rope has two specifications of 3.8mm and 4.9mm in outer diameter. It is made of 61 strands of galvanized steel wire rope of 0.4mm and 0.52mm. It is mainly marble, and granite mines are equipped with wire ropes. The outer diameter of the high-strength wire rope is 4.9mm, and it is a 61-strand galvanized wire rope. Different from the traditional wire rope, a special plastic coating similar to a protective layer is used on the outer surface of the wire rope, which firmly wraps the outer strand of the wire rope to maintain the compactness of its structure and prevent the wire rope from encountering during the cutting process. The wear caused by the hard spots, as well as the oxidation inside the wire rope under the action of cooling water, keep the wire rope with a long service life. The specifications of the 61-strand non-cleaning wire rope are the same as those of the traditional wire rope. In order to be more suitable for the production process requirements of the injection-molded wire rope, each wire rope has been specially cleaned during the production of the wire rope to remove the lubricating oil in the production process. The contamination of the wire rope by the sundries improves the adhesion between the polyurethane plastic and the wire rope when producing the injection-molded wire rope. In the core rope mechanism of this special surface-cleaning wire rope specially designed and developed for the injection molding production process to increase the adhesion of injection molding, one of the 7 steel wire ropes per share has a relatively large diameter, which is used to increase the external contact area of the steel wire rope. At the same time, it can improve the bonding characteristics of wire rope and plastic.
