In the past 10 years, the technical improvement of China's fastener manufacturing technology in the process of cooperation with foreign equipment is intangible. China's fasteners occupy a pivotal position in the global fastener industry.However, if you look at the product types, quality levels, technical standards, and resources and environment of the industry, there is still a big gap compared with foreign advanced levels. It is mainly manifested in the current dual pressure of "excess" and "shortage" in China's fastener production, but in addition to representing advanced technology hardware equipment can be bought, the "technical time difference" other than hardware equipment is China's fastener manufacturing technology The hidden factors and key factors behind.
Although there are strong fastener manufacturing companies in China, why do foreign equipment come to Chinese companies, and the utilization rate and products of equipment in use will be very different? What is the gap? This is what we call "technical time difference", That is, the technology gap between foreign hardware and other aspects of technology, use methods, production management and other aspects. Assessed according to the average level of domestic fastener manufacturing, especially where complex process special-shaped parts and process matching are involved, the overall level of "technical time difference" between domestic and foreign advanced levels is about 10 to 20 years.
"Technical jet lag" has some background reasons.
Educational background and development experience of China's fastener industry.
Human thinking mode, one is source education; the other is work experience. China's current professional and technical personnel of fasteners, from the post-60s to post-80s, education and work experience basically "introduction, digestion, absorption, improvement" model, it is difficult to stimulate original innovative thinking, most people do things based on " "Practical experience", knowing it, not knowing why, there are many feasible experiences with errors or no theoretical basis. Would it be better to do so?
In the drawing workshop of domestic fastener companies, when it comes to the "mold matching plan" of the drawing machine, no one seems to be ignorant, but a very common phenomenon, when foreign experts on-site review and see the "mold matching plan", Surprised, they found that the drawing process of most Chinese fasteners is based on the existing rich practical experience, which is logically “confusing and unreasonable”, and some even do not conform to the theory of metal material deformation. The result is, of course, "not necessarily infeasible but consuming resources or poor product quality", which is one of the reasons why foreign equipment is not so good in the hands of domestic users.
Disagree with the existence of "technical jet lag".
Domestic fastener experts usually do not agree that their process technology is not advanced enough, especially large fastener companies.They have been doing this for more than 30 years. Their full experience has become an obstacle to accepting new ideas, and it will not be easy. To deny yourself is often due 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 current technical experts "travel" to China in the next 20 years, will they still be "experts" of that era? The answer is no. This proves that the "technical jet lag" mentioned above exists.
How to accelerate and shorten the "technical jet lag".
First of all, we should acknowledge the existence of "technical jet lag", how to speed up the shortening of "technical jet lag"? Some people say that we have to wait for the era when the post-90s or post-00s became the backbone, and we have innovative thinking for them in education. ? Wait?
Generally, what we know as "advanced foreign technology" refers to "advanced equipment". Although many domestic technicians have many years of experience in using foreign equipment, this does not mean that they understand the design principle of the equipment and may not be able to replicate it. Or it is very good to absorb and improve. In the process of using the equipment, the personnel of foreign companies frequently contacted are basically "after-sales service" rather than technical designers, so they can't learn the core technology.
In addition, technology and equipment are inseparable, and 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 of equipment, conditions, pre-processing and configuration of materials Comprehensive macro processes such as schemes, daily maintenance management, etc., rather than the work scope of the "Technical Process Division" within the enterprise.
Hardware equipment that represents advanced technology can be bought, and the "craftsmanship" that represents software is difficult to buy. It can only be learned and accelerated!
"Technical jet lag" is not enough to catch up.
"Technical jet lag" is an objective existence. First of all, we must clear our own inherent concepts, that is, the "empty cup principle", and especially recognize that we have a gap. Create learning opportunities. Fortunately, today's Industry 4.0 and China-made "2025" complement each other, many foreign experts stand on this "side of the jet lag", without crossing them to be with us in the same era, four dimensions (time) It can become three-dimensional.If we can create opportunities or use opportunities to learn the details of the technology, we should know the details and know why, it is not impossible to accelerate the shortening of "technical time difference" from now on, and no longer Manufacture of excess low-end fasteners.
