In the past 10 years, the technological improvement in China's fastener manufacturing technology has been invisible in the process of cooperation with foreign equipment. China's fasteners occupy a pivotal position in the global fastener industry. However, there is still a significant gap in the types of products, quality levels, technical levels, resources and environmental investment within the industry compared to advanced foreign levels. The main manifestation is that there is still a dual pressure of "surplus" and "shortage" in China's fastener production. However, in addition to representing advanced technology and hardware equipment that can be purchased, The "technological time lag" outside of hardware equipment is a hidden factor and key factor in China's backward fastener manufacturing technology. Although there are powerful fastener manufacturing companies in China, why are there significant lags in the utilization rate and products of foreign equipment used by Chinese enterprises? Where is the gap? This is what we call "technological time lag", which refers to the technological gap between foreign countries in terms of processes, usage methods, production management, and other aspects beyond hardware equipment. According to the evaluation of the average level of fastener manufacturing in China, especially in areas involving complex process shaped parts and process matching, there is a "technical time lag" between the domestic and foreign advanced levels, which is about 10 to 20 years. The 'technical time lag' has a certain background reason. Education background and development experience of China's fastener industry. The human thinking mode is derived from education; The second is work experience. The current professional and technical talents in China's fastener industry, from those born in the 1960s to those born in the 1980s, have a basic education and work experience of "introducing, digesting, absorbing, and improving", which makes it difficult to stimulate original innovative thinking. Most people work based on "feasible experience", knowing it but not knowing its reason. Many feasible experiences have errors or lack theoretical basis. Would it be better to do so?
When it comes to the drawing workshop of domestic fastener enterprises, it seems that no one is ignorant of the "mold matching scheme" of wire drawing machines. However, a common phenomenon is that when foreign experts review and see the "mold matching scheme" on site, they are surprised to find that the majority of Chinese fastener drawing "mold matching processes" (all based on existing rich practical experience) are logically "very chaotic and unreasonable", and some even completely do not comply with the theory of metal material processing deformation, The result, of course, is that "it may not be feasible but it consumes resources or has poor product quality", which is also one of the reasons why foreign equipment cannot produce products that are so good in the hands of domestic users.
Disagree with the existence of 'technical time lag'.
Domestic fastener experts usually do not agree that their process technology is not advanced enough, especially for large fastener enterprises. They have worked in this industry for more than 30 years, and their rich experience has become an obstacle to accepting new thinking. They do not easily deny themselves, and often attribute the backwardness of products to the lack of advanced equipment. In fact, every scientific and technological breakthrough is a process of repeatedly denying existing existence, and denying or questioning is a prerequisite for innovation.
That is to say, if we allow current technical experts to "travel" to China in the next 20 years, will they still be industry experts of that era?
