The notebook computer hinge is an important functional structural part connecting the notebook computer display module and the host module. With the replacement of notebook computers, the notebook computer shaft needs to meet the needs of customers with more flexible flip angles, smaller volume, lighter weight, better performance, and diverse types.


Qinhuangdao Zhongwei Precision Components Co., Ltd. (hereinafter referred to as "Zhongwei Precision" or the "Company") has been engaged in consumer electronics precision shafts for more than ten years. With its strong R&D strength and advanced production system, it can quickly respond to customer needs and produce high-quality The high-quality shaft products occupy the market with high-quality, thin, precise and intelligent shafts, and have a high reputation in the industry.


After years of market development and customer accumulation, the company has continuously enhanced its market influence. Zhongwei Precision has rich industry experience in the field of notebook computer hinges. The issuer has established continuous and stable cooperative relations with world-renowned notebook computer foundries such as Lianbao, Compal, Quanta, Wistron, and Baolongda. In addition, Zhongwei Precision also has a research and development and production base in Beijing. With its high-quality products and professional services, it has been highly recognized by customers all over the world. At present, the company has a total of 120 patents, of which 6 are invention patents, 112 are utility model patents, and 2 are design patents. In the future, the company will continue to adjust production according to the needs of different customers, so as to ensure the rapid delivery of large-volume, customized and multi-type shaft products.


Before 2008, there were only a few laptop hinge manufacturers in mainland China, with an annual shipment of less than 1 million sets. With the rapid development of the industry, a large number of small and medium-sized enterprises have entered the field in recent years. At present, the industry-leading shaft manufacturers are mainly Taiwanese companies or their subsidiaries in mainland China, including Xinrixing, Zhaoli Industry, Xinhe Technology, etc. They have been operating in the shaft field for many years and have relatively rich technical reserves and experience accumulation. , Formed a relatively close cooperative relationship with customers, especially large customers.


With the impact of industrial transfer and the growing consumer market of electronic products in my country, the manufacturing industry of notebook computer shafts in China has grown rapidly. In recent years, there have been a large number of small and medium-sized enterprises producing notebook computer hinges in mainland China. Although domestic enterprises still have a certain gap with international large-scale enterprises in terms of R&D capabilities and management capabilities, close exchanges in the industry will effectively drive domestic enterprises to improve rapidly. With the help of industrial transfer, domestic enterprises can improve their own management capabilities, accumulate research and development experience, increase international market share, and enhance market competitiveness by strengthening cooperation with foreign manufacturers and introducing advanced production equipment. In recent years, Taiwanese manufacturers have also faced the impact of rising labor costs and declining gross profit margins, and their share has been eroded year by year. With more mainland manufacturers mastering core technologies and the trend of localized procurement, domestic notebook hinge manufacturers are expected to face opportunities for industrial transfer.


At present, domestic shaft manufacturers are mainly concentrated in the Yangtze River Delta, Pearl River Delta and other regions.


Over the past ten years, the center of the global manufacturing industry has gradually shifted to China. Computer, camera and other foundry manufacturers have set up factories in the mainland. They have the advantages of industrial clusters, manpower and technology, and manufacturing costs. It has gradually become the main production area for notebook hinge manufacturers.
