The quality control room is a key area for product quality control, which involves the whole process from raw material control, production and processing, product manufacturing to finished product testing to ensure that product quality meets predetermined standards and regulatory requirements. The work of the quality control room includes not only the supervision of the quality control of the production site, but also the supervision of the operation, hygiene and environmental hygiene of the production personnel, as well as the execution of the production process. In addition, the quality control room is also responsible for the control and handling of non-conforming products, including procurement, inventory, supervision and inspection of raw materials, as well as the testing of temperature and humidity data corresponding to the working environment of each workshop.
