Daoke Dao Laser Welding for New Energy Vehicle Battery Pack Covers: Safe and Hermetic Sealing
Battery pack safety is the core requirement for new energy vehicles, and the sealing performance of the battery pack cover directly affects operational safety. Traditional ultrasonic welding for battery pack covers often causes vibration damage to internal cells and fails to ensure long-term hermeticity. Daoke Dao plastic laser welding equipment solves these pain points with advanced transmission welding technology.
The equipment adopts a non-contact welding method with no mechanical vibration, avoiding hidden damage to sensitive components such as battery cells and PCBs. It achieves a welding precision of ±0.05mm, ensuring uniform and continuous welds that meet IP68 waterproof and dustproof standards, effectively preventing electrolyte leakage and moisture intrusion. Compatible with common battery pack materials such as PC and modified PP, it supports customized welding paths for complex 3D contours of battery covers.
Compliant with IATF 16949 automotive industry standards, the equipment features stable laser power output (fluctuation ≤±2%) and a service life exceeding 20,000 hours. It can be integrated into automated production lines, with a welding speed of 0.5-5m/min to meet mass production needs. For new energy vehicle manufacturers seeking reliable battery sealing solutions, Daoke Dao provides a safe and efficient choice. Contact us for customized solutions.
