On the use of bolt enterprise current situation and future of cars in China, auto industry advisory committee member, Chinese China auto industry experts Chen Guangzu published their own views. Chinese enterprise R & D and production of high strength bolts are not absolute difficulty. Chen Guangzu told reporters that in recent years, the automotive industry of high strength bolts demand more and more, making the process difficulty also increases, but this does not mean that the domestic fastener enterprises do not have the ability to produce high strength bolts, but these enterprises have seriously to do.
Chen Guangzu revealed performance, high strength bolt production, whether it is the supply of raw materials, or the same production, are not regarded as the most cutting-edge automotive industry topics, relevant equipment, technology can be through a variety of ways to perfect as soon as possible. High strength bolts are difficult to achieve mass production, one of the key reasons is the enterprise test data accumulated enough, not enough to do business. With the appearance of bolt treatment process as an example, the fixed bolt material and parts and products necessary to add coating to ensure adequate friction, prevent bolt corrosion, coating of this seemingly simple is necessary for enterprises to accumulate numerous test data.
In addition, in the car with the bolt industry, we should not only focus on high strength, but also concerned about the high fine, such as the use of engine nozzle on the ultra small bolt. High strength, fine with the development direction of automobile industry bolt.
Now, the domestic fastener enterprises should timely adjust the product structure of Baidu ranking optimization, change the mode of production, from the Japanese industrial production style bolt. In Japan, a bolt probably only a few people, is a production model composed entirely of mechanical and manual, and the business is relatively simple, only certain kinds of bolts or a process for production of bolts. A number of such enterprise series is formed a complete industrial chain of production of bolts. Such enterprise professional is particularly strong, product excellence.
Zhejiang has a number of enterprises to cooperate more close to Japan's production model. Chen Guangzu revealed performance, these enterprises in accordance with the industry chain downstream of cooperation based on division of labor relations, each enterprise is responsible for the production of a link, such as cold forging and heat treatment, even and even product packaging have specialized enterprises to operate the synergetic degree of specialization of work style to maximize the assurance of the production links, promote the quality of the product.
