Dongguan Sinbo Precision Clutch Parts Processing Case: Technological Innovation Solves New Energy Vehicle Transmission Challenges​

In the context of the rapid development of new energy vehicles, the precision and reliability of core components have become the key to industry competition. A recent clutch parts processing project completed by Dongguan Sinbo Precision for a leading new energy vehicle manufacturer has successfully solved the performance bottleneck of traditional processing technology in high - speed and low - noise scenarios through end - to - end technological innovation, setting a benchmark in the field of high - end manufacturing.​

The third - generation electric drive system developed by the vehicle manufacturer requires clutch parts to operate without failure at a high speed of 8,000rpm, with noise control below 45 decibels and a service life of more than 300,000 kilometers. Facing this challenge, the technical team of Dongguan Sinbo Precision deeply analyzed the working conditions and formulated a three - dimensional solution of "material innovation + process reconstruction + intelligent inspection":​

• Material end: Aviation - grade titanium alloy TC4 - DT is selected, and the density of the material is improved through powder metallurgy sintering process, so that the tensile strength reaches 1,100MPa, while the weight is reduced by 40% compared with traditional steel parts;​
• Process end: Five - axis 联动 high - speed milling technology is adopted, combined with laser surface texturing treatment, to form micron - level honeycomb oil storage tanks on the surface of the friction plate, controlling the friction coefficient fluctuation within ±3% and effectively reducing noise;​
• Inspection end: An AI visual inspection system is deployed to conduct 100% full inspection of 18 key indicators such as part tooth shape and surface roughness, with dimensional tolerances controlled within ±0.005mm.​

After 1,200 hours of bench testing, the batch of clutch parts showed stable performance in the temperature range of -30°C to 120°C, with a transmission efficiency of 99.2% and a noise value controlled at 42 decibels, far exceeding customer expectations. The technical director of the vehicle manufacturer commented: "Dongguan Sinbo Precision's solution has improved the comprehensive performance of the electric drive system by 30%, providing core support for the driving range and NVH performance of our models."​

The success of this case not only demonstrates Dongguan Sinbo Precision's technical accumulation in the field of precision machining but also highlights its transformation capability from "part processing" to "system solutions". At present, the process has applied for 3 invention patents and is being promoted in the new energy commercial vehicle field.​
