After high-frequency opening and closing tests, it can withstand more than 12,000 openings and closings without loosening or jamming, and the opening and closing are smooth. At the same time, automated assembly equipment is equipped to ensure the assembly accuracy of each hinge, avoiding the omissions of manual assembly; in the surface treatment link, the high-temperature curing environmental protection spraying process is adopted, combined with electrostatic spraying technology, the coating adhesion is strong, not easy to fall off or scratch, the color is uniform and full, and at the same time, the color, logo and pattern can be customized according to customer needs, meeting the personalized bulk purchase needs. The spraying process is environmentally friendly throughout, no harmful gas emissions, in line with green production standards, taking into account quality and environmental protection.

　　Standardized quality control, full-process inspection, eliminating unqualified products from leaving the factory - the factory has established a "full-process, multi-dimensional and strict standard" quality control system, which runs through every link of production. From raw material warehousing to finished product delivery, 8 inspection checkpoints are set up, equipped with a professional quality control team and precision testing equipment, ensuring that each large metal pencil box meets the quality standards. When raw materials are put into storage, the hardness, thickness and environmental protection of the substrate are fully inspected, and unqualified substrates are resolutely rejected; during the production process, key processes such as stamping, assembly and spraying are monitored in real time, and the product size, shape, hinge opening and closing, coating adhesion, etc. are sampled and inspected. If problems are found, the machine is stopped for rectification immediately to ensure the product quality during the production process; before the finished product leaves the factory, a comprehensive inspection is carried out, including compression test, impact test, sealing test, environmental protection test, etc. Each product must pass a strict inspection before leaving the factory, with a pass rate of more than 99.8%, completely eliminating unqualified products from flowing into the market, making customers worry-free about purchasing. At the same time, the factory establishes quality control files, and the test data of each batch of products can be traced, realizing "quality traceable and responsibility accountable", highlighting the factory's responsibility.
