The Shinkansen consists of 16 cars, and about 20,000 screws are used in the whole body. Due to high-speed driving and rail friction, the vibration is great. Generally, nuts can't stand it, and they are easy to loosen and fall off. A train full of passengers is in danger of disintegration, so the nut must not be loosened. In other words, 20,000 nuts are 20,000 safety hazards. At present, China has not mastered the production technology of high-end nuts, and the small bolts are completely consistent, which contains technical content unimaginable to ordinary people.
According to the statistics of China Writing Instrument Association, including refills, the output of ballpoint pens in China has exceeded 40 billion. Numerically, we are a well-deserved pen-making country, but we are not yet a pen-making country. Chen Sanyuan, honorary vice chairman of China Writing Tools Association, said: "There are more than 20 processes to produce a small ballpoint pen. Traditional processes need to be handled separately. " Thereby improving the quality and production efficiency. And rely on free-cutting stainless steel wire imported from Japan. At the same time, the matching ink should also be imported from Germany, Japan and other countries.
Behind industrial technology is the spirit of working people. Producers bet on personality with the sole purpose of gaining the recognition of consumers. This is a common phenomenon in the Japanese market. In recent years, China's manufacturing industry has made great breakthroughs, created many miracles, made every effort, and even painstakingly faced the status quo of things to satisfy the most discerning consumers. This is the importance of core technology and originality. In the near future, we in China will also produce nuts and ballpoint pens for high-speed rail.
