The supply chain structure of the national tempered glass industry is relatively complete, covering raw material procurement, production and processing, sales and other links. In the procurement of raw materials, enterprises usually choose suppliers with good quality and reasonable prices to cooperate to ensure the stable supply and quality of raw materials. In the production and processing links, enterprises need to have advanced production equipment and technical level to improve production efficiency and product quality. In the sales link, enterprises need to establish a perfect sales network and customer service system to meet customer needs and provide quality service. However, there are some potential risks and bottlenecks in the supply chain. Fluctuations in raw material prices may lead to higher business costs; The tightening of environmental protection policies may increase enterprises' environmental protection investment and operating costs; Deficiencies in some parts of the supply chain can lead to problems such as production disruptions or delivery delays. Therefore, enterprises need to strengthen supply chain management, optimize supply chain structure and improve supply chain stability and flexibility.
