 | Suspension products Suspension arms products adopt 315T hydraulic equipment stamping, Japan OTC automatic welding robot, and have rational process arrangement to guarantee good tensile and stable shape and position dimensions. |
 | Steering products We have customized special oil for ball-pin with reference to similar product technology of Japan and South Korea, improvement and innovation on ball bowl structure and dust cover formula, as well as, cooperation (formula property owned by Yongxin) with domestic famous oil company. The ball-pin machining is adopted high-precision turning and rolling ball-pin special machine and automatic robot assembly line. |
 | Shift control mechanism products At present, Yongxin has more than ten kinds of plastic structure and metal structure shift control mechanism, and the contradiction between control gaps and friction can be effectively overcome by rolling of metal ball-pin after finishing and with special gaps compensation structure. |
 | Carbon canister assembly Yongxin mainly studies the effect of carbon canister L/D, depth of absorptive pipe, 3 position and vapor velocity on performance, and utilizes patent innovation structure (National Patent No: ZL20062 0101951.9) to enhance its adsorption capacity by change the trend of fuel steam; it is detected by national institutions that the product working ability is in leading place at home, and is listed as national torch project. The product has passed environmental protection authentication of national environmental protection industry association. |
 | Oil cup assembly Using America imported vibration welding equipment, and being assembled in no dust assembly workshop to guarantee that the product has good sealing performance and cleanliness. |
