Value Upgrade with Cell Insulation Printing Mass Production Line + High-Shear UV Insulation Ink!​

1. Insufficient Voltage Resistance Poses Safety Risks: The air gaps in mainstream blue film insulation layers make them prone to partial discharge under high voltage; their withstand voltage is only 2500V, far below the reliability requirements for 800V platforms.
2. Mechanical Strength Inadequate for New Structures: Under CTB/CTC technologies, the shear strength of blue film's adhesive process is insufficient to prevent cell displacement caused by vehicle vibration, potentially leading to structural deformation.
3. High Costs: Requiring additional components like metal top covers for insulation protection increases material costs, and processes like cutting and pasting result in material utilization rates below 70%, reducing production efficiency.

• Superior Performance Parameters: Withstand voltage >6000V (2.4 times that of blue film), shear strength ≥15MPa, heat deformation temperature >120°C, capable of withstanding extreme temperatures from -40°C to 200°C and 95% humidity aging tests.
• Solving Process Pain Points: Combines 6 specially synthesized resins with nano-level printing technology for micron-level precision printing, adapting to complex structures like prismatic cell edges and cylindrical cell curves, avoiding uneven thickness and edge bleeding found in traditional powders.

1. Precision Positioning + Rapid Curing: Machine vision systems achieve ±5μm printing precision; UV curing technology enables second-level curing, achieving a first-pass yield of 99.9%.
2. Flexible Production + Green Compliance: Compatible with various cell types (prismatic, cylindrical, blade); material utilization over 99%, no splash loss, compliant with EU RoHS/REACH regulations.
3. Full Process Automation: Integrates laser cleaning, printing/curing, performance testing, etc., significantly boosting efficiency and consistency.

• Cost Optimization: Replaces the "blue film + metal top cover" scheme, eliminating top cover costs and reducing material waste by 30%.
• Process Upgrade: UV printing allows precise masking for poles, explosion vents, filling holes, etc., with high surface consistency.
• Efficiency & Quality Boost: Automation reduces manual intervention; online inspection ensures significantly lower defect rates.

• Patent Portfolio: Covers key areas like laser cleaning (pre-treats cell surfaces), nano-printing/UV curing (solves adhesion issues), and comprehensive performance testing (ensures product consistency).
• Meeting Core Industry Demands: Addressing the core drivers of safety, lightweighting, and cost reduction for power batteries, Keremins' solution has become a key supplier in the high-voltage battery insulation field.
