Fujian Haian Rubber Co., Ltd. Since the second half of 2006, Haian Rubber has decided to cooperate with Beijing Rubber Industry Research and Design Institute and Rubber College of Qingdao University of Science and Technology to jointly develop high-performance giant engineering radial tire production technology on the basis of the original one-stop bias tire consumption quota contracting service. After the R&D personnel of the factory tackled key problems and adopted the giant radial tire retreading technology, Haian Rubber Company made a number of key technical breakthroughs in tire structure, rubber compound formula and process technology, forming the largest complete production technology of 57 "series engineering radial tire products in China, and invented six national utility model patents (tire film compression device, placenta storage device, six-jaw pliers, tire stretcher, tire pneumatic suspension and buckle ring) and design patents. On June 30th, 2008, the first 37.00R57 giant engineering radial tire of Haian Rubber Company was successfully developed and rolled off the production line. Since then, it has owned the independent intellectual property rights of the production technology of the largest series of 57 "giant engineering radial tires in China, and at the same time broke the monopoly situation of giant engineering radial tires abroad. On April 24th, 2009, Haian Rubber Company's 57 ″ series of giant all-steel radial tires successfully passed the scientific appraisal of China Petroleum and Chemical Industry Association (Sinopec Xie Kejian Zi (2009) No.032) and was awarded to Sinopec on 2010. On this basis, Haian Rubber Company has successfully developed giant engineering radial tires with specifications of 46/90R57, 50/80R57, 40.00R57, 36.00R5 1, 30.00R5 1, 27.00R49 and 24.00R49, on April 38, 2065. The load, safety performance, wear resistance, puncture resistance, heat dissipation, grip and service life of the product can be comparable to those of imported products.
Tested by the National Tire Quality Supervision and Testing Center for many times, they all meet the national standards of GB/T 1 190-2009 and GB/T2980-2009. By the end of 20 14, the output value of equipment has exceeded 3 billion yuan, and it is expected to exceed 810 billion yuan in the next five years.
