Ningbo Yili Shock Absorber Co., Ltd. (Ningbo Yili Damper Co., Ltd.) was founded in 1995, with 28,000-square-meter building area, located in Ningbo Economic & Technical Development Zone (National Level). We have been devoting to the developing, design and manufacturing of shock absorbers and gas springs for automobiles, recognized as a Hi-tech enterprise with integrated business of development, manufacturing and technical support.
We have broad application range of shock absorbers for automobiles, more than 300 categories in 2 series which are for suspension system and non-suspension, safe and reliable, with long usage life. We introduce piston rods with micro crack chrome plating and double-lip seal--the latest technology to our shock absorbers. We also have extensive range of gas springs for automobiles, with more than 200 categories in 3 series used on engine hoods, trunks and seats. We are one of the first manufacturers who develope and manufacture the gas spring with a special longitudinal groove inside the pressure tube(the damping properties can be optimized to the application) and rigid lockable gas springs.
We follow the philosophy “Science and technology is the first productivity” by close cooperation with universities, scientific research institutes and close technique communication with domestic and overseas companies in the field, to improve our employees’ professional behavior and the processing equipment, and to purify the Quality Assurance System continuously. Based on our service philosophy “credibility & integrity, customer first, quality first”, our aim is chasing for the complete satisfaction of our honorable customers.
Research & Development
We follow the philosophy “Science and technology is the first productivity”，cooperate with colleges and universities, scientific research institutes and keep close technique communication with domestic and overseas companies in the field. Owning a professional R&D team and a design center using CAD, Pro/E and CATIA, We are capable of developing new products independently as required; we are one of the biggest manufacturers that manufacture the monotube gas spring with a special longitudinal groove inside the pressure tube(the damping properties can be optimized to the application) and rigid lockable gas springs.
Quality Assurance System
We are ISO9001:2008 and TS16949: 2009 certified company. We have an experienced quality control team and series of advanced testing equipment. Our quality inspection process covers the incoming inspection of raw material and outsourcing parts, process inspection and the finished products inspection. We operate the total quality management and in-process inspection, every working spot has the self-inspection process to achieve zero defects.
Advanced processing equipment is the prerequisite of the high quality products and high-efficient production. We have one production line with monthly output of 100,000 shock absorbers for automobile suspension, 1 line with monthly output of 80,000 shock absorbers for non-suspension, 1 line with monthly output of 150,000 gas springs for engine hoods and 1 line with monthly output of 100,000 rigid adjustable gas springs for auto seats. We have more than 80 sets of manufacturing equipment such as automatic steel-tube cutting machines, automatic chamfering machines, automatic MAG spring holders & bottom heads welders and an automatic Ω static painting line. Through the continuous technique improvement, some special equipment have been updated to be computerized to assure the product quality and improve the production efficiency.
