EV Battery Manufacturing Challenges
Battery pack painting requires:
Prevent electrolyte from contacting spray paint
Withstand baking temperature (≥180°C)
Efficiently cover irregular shapes
Core functions of spray paint tape
Chemical barrier: prevent paint from penetrating into the battery insulation layer to avoid the risk of conductivity.
High temperature stability: maintain adhesion during baking to avoid falling off.
Quick application: self-adhesive design reduces labor time and is suitable for automated production lines.
Comparison with traditional masking methods
Paper-based tape: easy to burn at high temperatures, generating smoke pollution.
Silicone tape: residual adhesive requires chemical cleaning, increasing costs.
Case Study
After Tesla adopted spray paint tape, the battery pack insulation defect rate decreased by 60% and the rework time decreased by 30%.
Conclusion
In electric vehicle manufacturing, spray paint tape is the key to ensuring battery safety and production efficiency.
