In the product showroom of Yongkang Feishen Group, a newly developed ATV is particularly eye-catching. According to Shen Changqun, the group's chief engineer, the car can not only be flat on deserts, swamps and other terrains, but also has two invention patents and more than 10 appearance patents. It is a new one with pure "Yongkang bloodline". Products, the market price of more than 40,000 yuan. Under the situation that the domestic and international economic situation is becoming more and more complex and the export is severely challenged, the Yongkang leisure sports car industry has achieved eye-catching performance. From January to August, the export volume exceeded 5 billion yuan, a year-on-year increase of more than 20%. "The secret of its success is to change manufacturing to 'intelligence' and rely on technological innovation for development." Yesterday, Xu Guangyuan, deputy secretary general of the Provincial Leisure Sports Car Industry Association said. Seven years ago, the wave of scooters swept through Yongkang, and there were more than 700 leisure sports car manufacturers in the area. In recent years, especially after the financial crisis in 2008, the market for leisure sports cars has turned sharply, and Yongkang leisure sports car companies have rapidly shrunk to more than 30. The leisure sports car industry, which has always been regarded as a counterfeit “hardest hitâ€, has therefore quieted down. The provincial leisure sports car industry association has not received an application for rights protection. Without the worries of counterfeiting, Shen Changqun can fully devote himself to research and development. The research team of the company has expanded from the original 10 people to more than 200 people. The number of patents applied for one year has reached more than 60, of which there are 6 invention patents. The mastery of core technology has locked in large customers in Europe and the United States, and orders have continued to grow. From January to July this year, the sales of Feishen ATVs increased by 40%. It is estimated that this year's exports will reach 200 million US dollars, ranking first in Jinhua's export enterprises. Bit. Yongkang Buyang Group is the largest manufacturer of security doors in China. Since last year, “Stepang†has witnessed a new wave of technological transformation. According to the relevant person in charge of the group: “The first new assembly line of steel door enterprises jointly developed by Buyang Group and Zhejiang University has been officially put into use. Through technological transformation, the production efficiency and product quality of the enterprise have been greatly improved. The previous five processes, one process for 12 seconds, now one process can be completed in 12 seconds." "In the next three to five years, we plan to invest 100 million yuan each year, and the original equipment will be eliminated within three years." Xu Buyun, chairman of Buyang Group, said that by then, workers will be reduced by 30% and production capacity will increase by 30%. The fully automatic assembly line is expected to achieve the goal of “one steel plate goes in and one door comes outâ€. According to statistics, from January to August this year, Yongkang City won a total of 2,018 national patents, an obvious increase. From January to July, the output value of Yongkang new products was 13.15 billion yuan, a year-on-year increase of 43.5%, and the output value of new products was 31.42%, a record high in recent years. Cheng Keke, director of the Yongkang Science and Technology Bureau, said: "Relying on scientific and technological progress, mastering core competitiveness, and accelerating the transformation of Yongkang from traditional hardware to modern hardware. This has become the consensus of many entrepreneurs in Yongkang." Yongkang plans to make efforts through three years. Large-scale enterprises in the city have basically realized design digitalization, production intelligence, management informationization, and sales network in science and technology innovation. Among them, design informationization has reached more than 90%, management informationization has reached more than 80%, and equipment informationization has reached more than 80%.
