Henan Zhongnan Industry Co., Ltd. was founded in 1981 and is affiliated to China Ordnance Industry Group Corporation. It is a large national second-class enterprise. In the 1980s, he made important contributions to China's national defense cause. In the early 1990s, due to the influence of the international environment, the military production tasks were reduced to zero. The Zhongnan people changed their concepts in a timely manner, actively implemented the strategic policy of the group company to “protect the army and transfer the peopleâ€, and fully exerted the advantages of military workers and production technology management. Market-oriented, self-funded to set up a synthetic diamond production line, began the development of synthetic diamond products. In the 10 years from 1993 to 2003, with the strong support of the group company and relevant state departments, five large-scale technical transformations were carried out on the synthetic diamond production line, and the synthetic diamond production line carried out five large-scale technologies. The transformation has brought about tremendous changes in the development and production capacity of synthetic diamonds: the production of synthetic diamonds has increased year by year, from the initial few million carats to hundreds of millions of carats in 2003; sales revenue has increased from several million to several Billion, the number of presses has increased from more than a dozen in 1993 to more than 300 at present, the level of equipment has been continuously improved, the press has been reduced from small to large, and the control system has evolved from constant source and constant voltage to computer intelligent control. The expansion and expansion of the productive area has increased by nearly 10 times. At present, the production capacity, sales revenue, sales volume and average profit of “Zhongnan†brand synthetic diamond are increasing substantially every year. Its comprehensive strength is ranked second in the country, and its technical level and comprehensive competitiveness are among the top in China's superhard materials industry. It has become a key backbone enterprise of artificial diamond production in China. Six technical renovations are underway. In 2004, the output of synthetic diamonds is expected to reach 500 million yuan, further consolidating the company's dominant position in the domestic diamond industry and successfully achieving the strategic policy of “protecting the army and transferring peopleâ€. This achievement has attracted the attention of the group company, and the synthetic diamond products have been listed in the key civilian product monitoring catalogue of China North Industries Group Corporation.
In the difficult, steady and rapid development process of more than ten years, Zhongnan Company has always supported technological innovation and took the road of quality and efficiency development. In the process of implementing the famous brand strategy, we adhere to the scientific and technological innovation as the core, and continue to upgrade the artificial diamond technology with continuous technological innovation, and push the product technology level to one level after another to meet the ever-evolving market competition. In order to improve the company's leading technology, we have developed and developed synthetic diamond components, the most advanced large-tonnage presses in China and hydraulic control and automation control systems, providing an operating platform for the development of synthetic processes. We have independently developed and expanded the cavity synthesis process, purification and selection process, imported international first-class diamond testing equipment, formulated enterprise product standards higher than the industry standard, and accelerated the pace of product integration with the international market. In particular, the self-developed powder catalyst synthesis process technology has taken the lead in the industry to completely eliminate the sheet-like catalyst synthesis process that has been inherited for more than 30 years, and completed a revolution in the field of synthetic diamond synthesis technology, which has become an important part in the history of domestic diamond technology development. milestone. The high-grade diamond produced by this technology was listed as “2004 National Key New Product†by the Ministry of Science and Technology.
Implementing the brand strategy, the company pays attention to the accumulation of intangible assets. Invested heavily in the establishment of an enterprise technology center in Zhengzhou High-tech Industrial Development Zone, attracting well-known experts and professionals in the diamond industry as consultants and backbones of the technology center, and using the technology center as an incubator for technology and projects to provide a powerful development for the company. Technical Support. In the past few years, two scientific and technological achievements have passed provincial-level technical appraisal, and six technologies have obtained national patent protection. Two scientific and technological achievements have won provincial and municipal scientific and technological progress awards. Today, the title of China Famous Brand Product obtained by “Zhongnan†brand synthetic diamond is a rich intangible asset, and these intangible assets will be transformed into huge economic benefits.
