Hengda "Leather Seamless Bonding Technology" Was Awarded The Qingdao Science And Technology Invention Award.

In March 19th, at the mobilization of Qingdao national technology innovation project and the conference on science and technology awards, the "seamless leather bonding technology" developed by Hengda Group was awarded the two prize of Qingdao science and technology award, and the highest prize of technology invention.

With the development of the global shoe making industry, the resource consumption disadvantage of China's footwear industry is becoming increasingly prominent. In addition to the current labor shortage problem faced by labor-intensive enterprises, the Chinese footwear industry, which is at the lowest end of the industrial chain, is in urgent need of scientific and technological innovation, and the industrial structure optimization and upgrading can be promoted by adjusting the structure.

As the vice chairman of the China Leather Association, Hengda Group has long taken technological innovation as the top priority of its work. Every year, 5.6% of its sales revenue has been invested in R & D, and has achieved rich research results based on the R & D platform of the "national accredited enterprise technology center".

305 national patents and 27 national standards have witnessed the strength of enterprises in technological innovation.

In particular, the company's self-developed "leather seamless bonding technology" and "bacteriostatic odor purification shoe production line" are listed as key national technological pformation projects. At present, these two projects have been officially launched in Hengda International Digital Industrial Park. The implementation of these two pipelines will become the first class and technology leading pipeline in the country, so that the industrialized operation of high value-added products of footwear will be realized in China.

It is reported that the scientific and technological invention award not only requires invention to be awarded the national invention patent, but also has originality, innovation and advanced nature. After implementation, it can create significant economic and social benefits. The "leather seamless bonding technology", which won the Qingdao science and Technology Invention Award, has not only won the national invention patent, but also has been listed as a national key support technology pformation project, and has won many provincial and national awards at the same time, and has reached the international leading level through the provincial scientific and technological achievements and new technology appraisal.

The technology is mainly to make full use of the information technology, so that the large leather of leather products can be cut off according to the design requirements under the control of the computer, and then adopt the self-developed high frequency bonding technology, so that the product can achieve seamless bonding effect, and the utilization ratio of raw materials can be increased to more than 17%.

After the promotion and use in the whole country, according to the 1.5 square feet per pair of shoes and 9 billion pairs of leather shoes in the whole country, the annual leather material can reach 2 billion 290 million square feet, and the gross leather output per cow is 40 square feet (which is equivalent to saving 57 million cows). According to the 25 yuan per square foot of leather, the annual savings can reach 57 billion 300 million yuan.

"Leather seamless bonding technology" can also be widely applied to leather products such as luggage, clothing, sofa, car seat and so on. It has made great contributions to building a resource-saving and environment-friendly society, and has also improved the core competitiveness of enterprises, and promoted the pformation and upgrading of enterprises to the technology intensive fashion industry.
