The electric drive production line of a leading new energy vehicle manufacturer has been upgraded
This customer originally adopted the atmospheric pressure immersion process. During the high-temperature and high-humidity tests, the product frequently experienced partial discharge issues, with a yield rate of only 82%.
Our solution: Customize a fully automatic VPI production line for it, integrating the entire process of vacuum degassing, pressure impregnation, and nitrogen-protected curing.
Outcome
The insulation qualification rate has been raised to over 99.5%.
The processing time per piece has been reduced by 15%, and production capacity has been increased.
Successfully passed the A-level supplier audit of the original equipment manufacturer.
