ROSO Automation Technology Co., Ltd. is a high-tech enterprise specializing in the research and development, production, and sales of zipper dyeing production lines. The company faced challenges in digitizing their machines and transforming from simple to smart manufacturing. Traditional zipper production was labor-intensive, incurring high labor costs with low product added value. The company also had to deal with the dual challenges of manufacturing and operation due to its business model of providing operating services to zipper manufacturers. The lack of digital systems in production and operation at the factory led to errors and omissions during material handover, inconvenient management of onsite logistics, and confusion regarding the locations of finished and semi-finished products. There was also no adequate mechanism for managing the dyeing formulas, which are central to the dyeing process.
