Jinan Yihua Tribology Testing Technology Co., Ltd is the first company specialized in tribology testing techniques and test equipment, test equipment development. Is a collection of scientific research, production, sales, technical services, academic exchange in one of the high-tech enterprises. Our company is a member of the National Tribology Society. Have excellent tribological test technology research, development experts and scientific and technical personnel. With a strong technical innovation capability, rich professional theory and practical experience, nationwide marketing network, has its own unique corporate culture. Since its incorporation, has successfully developed a four-ball test series, the special environment and working conditions and simulations using non-standard ring block series testing machine, face series testing machine, reciprocating series testing machine and high-speed, high temperature, vacuum, etc., special test machine. Manufacturing simulation point, line, surface and combined movement of all forms of friction, the fluid, solid, semi-liquid semi-solid materials and parts, and components on the tribological properties of the test. The products are widely used in petrochemical, automobile manufacturing, machinery, metallurgy, textile, building materials, light industry, aerospace, rail transportation, shipbuilding, universities, research institutes and other industries and units. In recent years, the company has a joint production and research widely and Tsinghua University, Zhejiang University, South China University of Technology, Institute of Metal Research Institute and other leading universities and research institutes, successfully obtained a number of results: the dynamic testing techniques used in friction and wear tests areas; the integrated use of electricity, liquid, light, sound, magnetic technology in friction wear test areas; small load, fretting wear, the way the test of high-frequency reciprocating motion. Has been developed with full intellectual property rights of a dozen made a number of inventions and utility model patents.
