Core Viewpoint - The article emphasizes the significant advancements in technology that have transformed the production and safety of sanitary pads, addressing women's concerns about the purity of materials and the safety of manufacturing processes [1]. Group 1: Production Process - The production process of sanitary pads at the Sofy factory in Yangzhou is meticulously monitored, with strict quality control measures in place from raw material selection to finished product delivery [3]. - Each batch of core raw materials must pass through three critical checkpoints before entering production: customs inspection reports, GB national standard testing, and microbiological testing [3]. - The factory employs a fully automated production line, minimizing human contact to reduce contamination risks, with only four workers needed for material installation [8][10]. Group 2: Quality Control - Quality control is a cornerstone of consumer trust, with each sanitary pad undergoing inspection by a specialized QC sensor equipped with high-precision cameras and over 300 sensors to detect even the smallest defects [12][14]. - Any defective products are physically destroyed to prevent them from leaving the factory, ensuring a zero-defect policy [16]. - The factory's quality assurance includes a four-day storage period for finished products to ensure they meet all safety standards before shipping [19]. Group 3: Safety Measures - The factory employs a comprehensive "macro + micro" protective system to maintain a sterile environment, including a positive pressure system and regular UV and ozone disinfection [10]. - Pest control measures are robust, with multiple monitoring and trapping devices in place, along with monthly inspections by a third-party pest control company [12]. - The transportation process is also tightly controlled, with checks on packaging and vehicle cleanliness to ensure product safety during delivery [19].
