Classification of bolt detection methods
-
China's bolt factory industry is still a developing industry, "big but not strong", "fat but not strong", and there is a large gap between the United States, Japan, South Korea and Taiwan, and there is a lack of technical services to solve mechanical fastening. Solutions to realize the digitalization of products, design, manufacturing and management, and the greening of products and manufacturing processes. It is understood that the development of China's bolts is under increasing pressure from resources and the environment. An important way to alleviate resource constraints is to develop green manufacturing. The development of bolts will continue to be actively promoted in the direction of brand management for a period of time to promote the full range of bolt project development.
There are two types of bolt detection: manual and machine. Manual is the most primitive and most commonly used consistent detection method. In order to minimize the outflow of defective products, the general production company personnel inspect the packaged or shipped products by visual inspection to eliminate defective products (defects include tooth injuries, mixing, rust, etc.).
The Chinese bolt factory industry must follow this trend and trend, strengthen strategic cooperation between enterprises, and improve the overall competitiveness of Chinese bolts. China lacks breakthroughs in the growth of core bolt technologies. At the same time, the living space of low-end products has been squeezed smaller and smaller. Foreign-invested enterprises through localization also have considerable cost advantages. Coupled with the advantages of technological brands, they have begun to enter the market space of the original independent brands.
