In the past 10 years, the improvement of fastener manufacturing technology in China is invisible in the process of cooperation with foreign equipment. China's fasteners play an important role in the global fastener industry. However, compared with the foreign advanced level, the internal product category, quality level, technical level, resources and environment of the industry are still far behind, which is mainly reflected in the double pressure of "excess" and "shortage" in China's fastener production, but in addition to representing the advanced technology and hardware Parts and equipment can be bought. The "technical time difference" beyond hardware equipment is the invisible factor and key to the backward fastener manufacturing technology in China.
Although there are strong fastener manufacturing enterprises in China, why are the utilization rate and products of the equipment in use very different when the foreign equipment arrives at the Chinese enterprises? What's the gap? This is what we call "technical time difference", that is, the technical gap between the technology, use mode, production management and other aspects other than the hardware equipment and the foreign ones. According to the evaluation of the average fastener manufacturing level in China, especially the places involving complex process special-shaped parts and process supporting, the "technical time difference" between domestic and foreign advanced level is about 10 to 20 years.
There are some background reasons for "technical time difference".
Education background and development experience of fastener industry in China.
The mode of thinking of human beings is source education and work experience. From the 60's to the 80's, the education and work experience of fastener professionals in China is basically "introduction, digestion, absorption and improvement" mode, which is difficult to stimulate original innovative thinking. Most people work based on "feasible experience", knowing it, not knowing why, many feasible experiences are wrong or without theoretical basis, will it be better to do so?
When it comes to the drawing workshop of domestic fastener enterprises, it seems that no one knows the "die matching scheme" of wire drawing machine, but a very common phenomenon, when foreign experts see the "die matching scheme" in the on-site review, they will be surprised to find that most of the drawing "die matching process" of Chinese fasteners (based on the existing rich practical experience), logically "very confused, unreasonable", some even finished All of them are not in line with the theory of metal material processing deformation, the result of which is of course "not necessarily infeasible, but the consumption of resources or poor product quality", which is one of the reasons why the products of foreign equipment to domestic users are not so good.
They do not agree with the existing "technical time difference".
Domestic fastener experts usually disagree that their process technology is not advanced enough, especially for large fastener enterprises. They have worked in this industry for more than 30 years, but their full experience has become an obstacle to accept the new thinking, they will not easily deny themselves, and they often attribute the backward products to the lack of advanced equipment. In fact, every scientific and technological breakthrough is a process of negating the existing existence, negating or questioning is the premise of innovation.
In other words, if we let the current technical experts "cross" into China in the next 20 years, will they still be the industry experts of "that era"? The answer is No. This proves that the above-mentioned "technical time difference" exists.
How to shorten the "technical time difference".
First of all, we should admit the existence of "technological time difference". How can we speed up the shortening of "technological time difference"? Some people say that we should wait for the time when the post-90s or post-00s become the backbone, and have innovative thinking in their education since childhood. What should we do now? Wait?
Generally, the "advanced foreign technology" in our cognition refers to "advanced equipment". Although many domestic technicians have many years of experience in using foreign equipment for many years, this does not mean that they can understand the design principle of the equipment, which may not be copied or well absorbed and improved. In the process of using the equipment, the personnel of foreign companies who contact frequently are basically "after-sales service" rather than technology Technical designers, therefore, can not learn the core technology.
In addition, technology and equipment are inseparable. Advanced equipment only represents a part of "advanced". Here, our understanding of technology should be all aspects of the product manufacturing process, including the use method, conditions, material pretreatment, configuration scheme, daily maintenance management and other comprehensive macro processes, rather than the work scope of "technology section" within the enterprise.
On behalf of advanced technology hardware equipment can be bought, on behalf of software "process" is very difficult to buy, can only learn, accelerate learning!
"Technical time difference" is not enough.
"Technical time difference" is an objective existence. First of all, we need to clear our inherent concept, that is, the "empty cup principle", especially to recognize that we have a gap. Manufacturing learning opportunities. Fortunately, today's industry 4.0 and 2025 made in China complement each other. Many foreign experts stand at the "end of the time difference". They can live in the same era with us without crossing them. Four-dimensional (time) can become three-dimensional. If we can create opportunities or make use of them, we can learn about the details of technology. We need to know why However, from now on, it is not impossible to accelerate the reduction of "technical time difference" and stop manufacturing products with low-end fastener surplus.
