At this year's two sessions in Zhengzhou City, the government work report made by Mayor Ma Wei clearly stated that it will enhance the driving force for innovation, take the construction of innovative cities as the starting point, and accelerate the implementation of the roadmap for the growth of science and technology enterprises and the construction of R&D centers. Accelerate the construction of the future science and technology city. At present, Zhengzhou's development is facing a historic opportunity. The construction of Zhengzhou Metropolitan Area in the Central Plains Economic Zone is set sail, the blueprint of the Zhengzhou Airport Economic Comprehensive Experimental Zone is drawn, the new urbanization is in full swing, and the new industrialization has a long way to go. Innovation is a powerful driving force for sustained, healthy and rapid economic and social development. .
Among the thousands of enterprises in Zhengzhou, there is such a group. They have leading core technologies. The products dare to compete with the world peers. They focus on innovation and always stay at the forefront of the industry. They are the representatives of Zhengzhou and the cities. Core competitiveness.
China's first shield manufacturing
The huge nose of 6.6 meters in diameter dragged a long fuselage of 136 meters. The nose and the section fuselage are connected by a bundle of thick connecting wires. The whole machine is like a static train, and it is like a dragon lying still.
In the large factory building of China Railway Tunnel Equipment Manufacturing Co., Ltd., the huge shield machine makes the first sighted people marvel. Wang Dujuan, deputy dean of the company's design and research institute, said that in the underground of Zhengzhou, there are nine such giants, along the planned subway lines 1 and 2, and the earth is chewing stones and turning over the river.
Five years ago, the domestic shield machine market was still the world of imported products. In 2008, the composite shield machine equipped with the China Railway Tunnel was first tested in Tianjin, and the monopoly market was broken. The value of the imported shield machine also dropped tens of millions. In 2012, 60% of the domestic shield machine market has been taken into the bag by China Railway Tunnel equipment, and its products are exported to Malaysia, Singapore, India and other places.
To build a shield machine, it is necessary to overcome three difficulties of integration of the whole machine, geological adaptability and automatic control technology. At present, only three companies in the country have production capacity, and China Railway Tunnel equipment is one of the best. They have a circular shield machine with a maximum diameter of 9.3 meters, and now they are making the world's largest rectangular shield machine, and will soon be able to wear a project under the Zhongzhou Avenue. The company is responsible for the national "863" project of large-diameter hard rock shield machine. At present, the complete set of technology has matured, and the hard rock shield machine market of 8 meters or more, which has been monopolized by foreign countries for a long time, will soon be broken again.
“The diameter of a hair is 0.06 mm, and the diameter of our product can be exactly one-thirtieth of that.†The product of Zhang Weifeng, an engineer at Zhengzhou Diamond Precision Manufacturing Co., Ltd., refers to the tool on industrial machine tools. Zheng Drill, which produces super-hard tools, is mainly used in the field of finishing, and the process requirements are strict.
The tool is referred to as the "teeth" of industrial machine tools. Whether the teeth are sharp and durable determines the efficiency, quality and cost of industrial manufacturing. Zhang Weifeng said that superhard tools use natural diamonds, synthetic diamonds and other materials with the highest hardness in the world. The processing difficulty is very high, and the requirements for machine tools and technical control are also very high. The use of the tool is different and the process requirements are different. Diamond tools for machining aircraft and automotive materials have a minimum diameter of only 2 mm.
At present, 90% of domestic automobile engine manufacturers are partners of Zheng Diamond. In the United States, Japan, Germany, Spain and other countries, Zheng Zheng products are available. Zhang Weifeng said that Zheng Drill’s current competitors mainly come from abroad, such as Germany’s Maple. The latter is a century-old enterprise that is well known in the world of tooling.
Since 2005, Zheng Drill has drafted and formulated seven product standards, five of which are industry standards and two are national standards. In 2012, Zheng Drill filed 150 patents.
The best-selling Hanwei sensor worldwide
It allows humans to grow up in the "clairs of the eye", and far away can be close to the eyes; it magnifies our sense of smell and hearing thousands of times, any subtle changes can be accurately captured. It is a sensor called "Electric Five." Henan Hanwei Electronics Co., Ltd. is the leading enterprise in the production of “Electric Fiveâ€. In 1998, the company started with sensors and broke the market monopoly of imported products. The cost of sensors dropped by more than half. At present, Hanwei's sensor categories involve gas, pressure, flow, humidity, pyroelectric, etc. The products are distributed in nearly 60 countries and regions around the world, and the gas sensor is the leading position in the domestic market, with a market share of 60%.
Relying on the sensor, Hanwei is stepping on the military Internet of Things industry. IoT technology is known as the third wave of global informationization. It is estimated to have a huge market of more than 100 billion yuan. Sensors are the key link of this technology. With the "core technology, key equipment and own" Hanwei, the development of the Internet of Things industry has a unique advantage. At present, Hanwei is the leading enterprise in the province's Internet of Things technology and a leading enterprise in the field of industrial safety Internet of Things. Chairman Ren Hongjun proudly said: "The domestic chemical park along the Yangtze River, the large gas group, the large oil refining and chemical enterprise are our business partners..."
With the rapid movement of the printer nozzle, a circular chess piece with a diameter of 5 cm and a thickness of 1 cm was completed. Zhengzhou Hongsheng Digital Technology Co., Ltd. printed the chess pieces with LED-UV curing ink, let us first appreciate the style of 3D printing.
3D printing, or “rapid prototyping technologyâ€, is a symbol of the third industrial revolution as it greatly shortens the process of industrial products from creativity to industrialization. The biggest bottleneck in this world-new technology is the material. Hongsheng Company is mainly engaged in digital printing inkjet ink, and has outstanding advantages in the development of printing materials. It has developed more than 100 kinds of more than 8,000 kinds of single products, and its products are distributed in more than 50 countries and regions around the world.
LED-UV curing ink is the latest material developed by Hongsheng. It can be printed on the substrate and can be cured in a few tenths of a second under ultraviolet light. It can be used as a material for 3D printing. Zhang Xiaohong, a director of the company, said that we are currently in the process of research and development of 3D printing materials, and actively build a 3D ink production line, which is expected to be completed and put into use within six months to one year.
China Railway Tunnel Equipment, Fu Nike, Zhongnan, Yellow River Cyclone, Hongsheng Digital, such enterprises relying on technical strength to stabilize the market, there are hundreds of Zhengzhou. They are scattered in the corners of the city, but they are not amazing, but they are stunted. They are the backbone of the Zhengzhou innovation team, and they are the shining business cards of “Zhengzhou Creationâ€.
