Professional operators wearing standard clean clothes and protective gloves follow a standardized dual station collaboration process: the first station accurately places the pump head on the mold, and the second station immediately places the corresponding plastic bottle cap. The entire process is carried out in a clean environment with constant temperature and humidity, strictly following the quality control system to ensure the sealing, hygiene, and structural stability of each finished product, fully meeting the high-end export quality requirements in various fields such as food and daily chemical.
