In the past 10 years, China's fastener manufacturing technology in the process of cooperation with foreign equipment, the technical improvement is invisible. China's fasteners occupy a pivotal position in the global fastener industry. However, there is still a big gap between the types of products, quality levels, technical standards, resources and environment in the industry and the advanced level of foreign countries. The main manifestation is that there is still a double pressure of "surplus" and "shortage" in China's fastener production, but in addition to representing advanced technology and hardware equipment can be bought, the "technical time difference" outside the hardware equipment is the invisible factor and key to the backwardness of China's fastener manufacturing technology.
Generally, the "advanced foreign technology" in our cognition refers to "advanced equipment". Although many domestic technicians have many years of experience in the use of foreign equipment, this does not mean that they understand the design principles of the equipment, and may not be able to copy or absorb and improve well. In the process of equipment use, the frequently contacted foreign company personnel are basically "after-sales service" rather than technical designers, therefore, they cannot learn the core technology.
