With the improvement of product appearance quality requirements, a single wire rope sling is easy to scratch the surface of the lifting object, which can no longer meet the needs. Then the synthetic fiber lifting belt developed and produced can solve this pain point very well. Then what is the production process of Slings belt?
The hoisting Slings belt of synthetic fiber is made of high strength polyester, polypropylene or polyamide industrial filament as raw material and woven by industrial loom. In production, the inspection of raw materials is the prerequisite for the quality assurance of slings belt products.
After testing qualified raw materials, enter the ribbon, dyeing, word process. Through warping, the filament yarn is processed into the warp shaft meeting the weaving requirements, and the loom is used to weave the belt. The leather is put into the dyeing tank for dyeing. The dyeing is different with different lifting weights, and the dyed leather needs to be mentioned, such as the company name and the logo of the lifting weight.
After the raw materials meet the quality requirements, the inner core is made. Through the core, core twist equipment processing into the requirements of the inner core. The semi-finished products of each process are equipped with skin and inner core and assembled into products conforming to technological requirements through core piercing process.
Finally, the stitch is uniform and beautiful, in line with the quality requirements. After the slings belt is made, the lifting belt of each specification shall be tested by tensile force of 1%. In order to verify whether the quality of the products produced conforms to the enterprise standard "Q/YZD01-92".
