Uncover what is the "technical time difference" in the fastener industry

In the past 10 years, in the process of cooperation with foreign equipment, the improvement of fastener manufacturing technology in China is intangible. China's fasteners occupy a pivotal position in the global fastener industry. However, there is still a big gap between the product category, quality level, technical level, resources and environment of the industry and the advanced level of foreign countries, which is mainly manifested in the double pressure of "surplus" and "shortage" in China's fastener production. However, in addition to representing the advanced technology and hardware equipment, The "technology time difference" outside the hardware equipment is the hidden factor and key to the backward fastener manufacturing technology in China< br> Although there are strong fastener manufacturing enterprises in China, why do the utilization rate and products of foreign equipment in use differ greatly from those of Chinese enterprises? Where is the gap? This is what we call "technology time difference", that is, the technology gap between China and foreign countries in terms of technology, use mode, production management, etc. other than hardware equipment. According to the evaluation of the average fastener manufacturing level in China, especially in the places involving complex process special-shaped parts and process matching, the overall level is about 10 to 20 years "technical difference" between the domestic and foreign advanced levels< br> There are certain background reasons for "technical time difference"< br> Education background and China fastener industry development experience< br> Human's mode of thinking, one is source education; Second, work experience. The current fastener professional and technical personnel in China, from the post-60s to the post-80s, have basically "introduced, digested, absorbed and improved" education and work experience. It is difficult to stimulate original and innovative thinking. Most people do things based on "feasible experience", and they know what it is, but do not know why. Many feasible experiences have errors or no theoretical basis. Would it be better to do so< br> In the drawing workshop of domestic fastener enterprises, when it comes to the "die matching scheme" of the wire drawing machine, it seems that no one knows anything about it. However, it is a very common phenomenon. When foreign experts see the "die matching scheme" in the on-site review, they will be surprised. They find that the "die matching process" of the wire drawing of most Chinese fasteners (based on the existing rich practical experience) is logically "very confusing and unreasonable", and some even do not conform to the metal material processing deformation theory, Of course, the result is "not necessarily impossible, but the consumption of resources or poor product quality", which is one of the reasons why the products of foreign equipment are not so good in the hands of domestic users< br> Do not agree with the existing "technical time difference"< br> Domestic fastener experts generally do not agree that their process technology is not advanced enough, especially large fastener enterprises. They have worked in this industry for more than 30 years, and their full experience has become an obstacle to accepting new ideas. They do not easily deny themselves, and 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, and negation or doubt is the premise of innovation< br> In other words, if we let the current technical experts "travel" to China in the next 20 years, will they still be industry experts of that era? The answer is No. This proves that the above-mentioned "technical time difference" exists< br> How to speed up and shorten the "technical time difference"< br> First of all, we should acknowledge the existence of "technology time difference". How can we speed up the shortening of "technology time difference"? Some people say that we should wait until the post-90s or post-00s when they become the backbone. What should we do now? Wait< br> Generally, the "advanced foreign technology" we know 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 copy or absorb and improve it. During the use of the equipment, the personnel of foreign companies who frequently contact are basically "after-sales service" rather than technical designers, so they cannot learn the core technology< br> In addition, process and equipment are inseparable. Advanced equipment only represents a part of "advanced". Here, our understanding of the process 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 the "technology and technology section" within the enterprise< br> Hardware equipment representing advanced technology can be bought, and "technology" representing software is hard to buy. We can only learn and accelerate learning< br> "Technical time difference" is not enough to catch up< br> "Technology time difference" is an objective existence. First of all, we should 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 made in China 2025 complement each other. Many foreign experts are standing at the "time difference" end. Without crossing them, they are in the same era with us. Four dimensional (time) can be changed into three-dimensional. If we can create opportunities or take advantage of opportunities, learn the details of technology, get to the bottom of the matter, and know why, it is not impossible to start from now, Accelerate the shortening of "technical time difference" and stop manufacturing products with excess low-end fasteners< br> Facing the opening year of the 13th five year plan in 2016, the development and wide application of some revolutionary technologies have made the reform of fastener technology an unalterable trend. This requires the improvement of the system, the role of the market, and more importantly, the change of our consciousness and the cultivation of core technologies. The development and glory of the fastener industry cannot be separated from the efforts of every industry personnel< br>
