Hundred years story
The rise of Northern Jiangsu Province, "steel curtain line city"
In Jiangsu Xinghua Dainan Town, there is a quietly flowing Mao shan. Through the mountains and rivers nourishes Mao, and the party people,
Also nourish a company and the world's giants to compete with the tire skeleton material production enterprises - Xingda Jiangsu steel cord Limited by Share Ltd.
From a only 10 workers, hundreds of thousands of Yuan belongings of town and township factories, to break the monopoly of foreign giants in the Chinese market, development
To have thousands of employees, hundreds of billions of dollars of assets of the modern private enterprises, the world's largest "steel curtain line city", Xingda only
For a short span of 20 years.
Xingda in 1986 founded cogeneration power plant and small achievements. However, director Liu Jinlan does not rest on its laurels rich, after many times of market research and test
The police, he set his sights on the "backbone" -- radial tire steel cord.
Steel cord product technology content is high, the quality requirements, known as metal products in the crown, to get involved in the field of great risk
. But Liu Jinlan its reason: the country vigorously road construction, car with the popularity of the radial tire rate will be greatly improved, used for meridian tyre steel cord
Line market demand will increase. "Steel cord is the national 'eight five' key research projects, the market potential, if not to engage in this project
Lost will be the development of opportunity."
However, enterprises in 1993 after go through untold hardships before they are put into production of steel cord, because of the backward production technology, technical strength weak,
Products such as low adhesive force and broken wire and other serious problems. More than 30 tons of waste makes Xingda a sudden loss of about 600000 yuan, which in the
Is an astronomical figure. Huge losses to Liu Jinlan bear a huge pressure. A local leader has ordered the steel cord in Xingda
Project dismount: "don't dismount you will become the history of sinners!" Liu Jinlan is straight spine replied: "this horse is
The history of sinners, his heart a horizontal, lead the whole plant workers and put into new technology attack. Foreign experts go, he set up
Its technical research team, continue to make the contrast tests data, has experienced countless sleepless nights and finally developed
A tension device, wire pre - variant, from the fundamental to overcome the technical difficulties. 1999, Xingda steel cord products for the first time losses
For profit.
After the development of the right track, in order to improve the qualified rate of the product, Xingda has invested heavily in Italy GCR company, Rhine, Germany
Si Yinjin advanced technology and equipment, the product added value is nearly doubled, the product qualified rate increased by 5 percentage points. But Liu Jinlan believes
, the foreign technology can only be transplanted, can not be cloned, innovation is the enterprise benefit growth and sustainable development. After digestion and absorption
, Xingda has independently developed a number of patented technology, its radial tire special high-performance new structural steel cord production technology was awarded 2004
National Science and technology progress two, and so on.
Innovation can not be separated from the talent. Over the past 20 years, Xingda has accumulated billions of dollars in assets, but in the eyes of Liu Jinlan, a high quality of personnel
More valuable assets. The steel cord is composed of a wire twisted. In the past, a steel wire broken, twisting machine is still running at high speed
, resulting in a decline in finished products. The six branch of a worker named Jiang Hua a mystery to solve this problem, and soon developed a broken wire
Protection technology, the steel cord product qualified rate increased by 1~2 percentage points. Liu Jinlan will this technology named "Jiang Hua broken wire
Law enforcement".
Today, Xingda has been among the three industries in the international, become the only domestic and foreign steel cord production enterprises to keep pace
Steel cord manufacturer. However, innovation has always been regarded as the source of development, the annual funding for R & D over sales of 3%,
A number of major innovative achievements in recognition of national, provincial and industry.
Xingda's rise so far, many people have asked where the secret. The secret: "Chairman Liu Jinlan puncture a fallacy with one remark on the surface of enterprise competition
Look at the quality of competition, the essence of the enterprise management level of competition, a deeper look is the competition of corporate culture. Xingda Lide',
Meritorious service 'corporate culture, make the enterprise rapid rise."
Old worker Xu Yun told such a story: in 2002, Xingda to expand the size of the market to seize the market, with only 9 months to build
With an annual output of 40000 tons of Xingda six plant, production capacity has doubled. But six plant new workers accounted for 95%, the technology has been affected by the new steel
Cord yield. Old factory workers after the use of the initiative to help new workers to master the technology. Just six months, Xingda six
Plant yield increased rapidly." Worker Ma Weijun said: "I have received the old staff training new workers. Now I do
As an old worker, workers need to keep Xingda traditional mentoring."
Liu Jinlan memories of this period of time with deep feeling: "Xingda, whether it is a worker or a leading cadres, in different positions to do different
Master, like the root cord twisted into rope, energetic, hard to resist the risk, condensed into a dare to cross to go abroad to fight the first-class Caine
Strong collective."
