sanding belt splicing tape
For docking tape, the largest roll-to-roll continuous production equipment with a width of 1.3 meters is adopted for the production and processing of master coil materials, which can ensure the uniformity and stability of each roll of products in quality, and the automatic cutting equipment can keep the width of each roll of tape consistent. Because the manufacturing standards of automobile industry products are followed, there are strict testing requirements and records for each batch of products before leaving the factory, such as thickness test, body tensile strength test, flexural (fatigue resistance) test, and other size, quality and specification control tests. All product batches can be traced to each step of the production process through the product label number.
