P-SDC500D Wide width coating machine Solve Your Biggest Electrode Production Challenges
Traditional separate coating and calendering lines create bottlenecks, increase handling defects, and consume valuable factory space. Our Speed Wide-width Double-layer Coating Calender Machine is the integrated, future-proof answer.
1. Unmatched Speed for Gigafactory Economics:
Our machine’s 150 m/min capability and ultra-wide web processing mean you produce more electrode square meters per hour. This directly lowers your cost per kWh, the single most important metric in competitive battery manufacturing.
2. Precision Engineering for Superior Battery Quality:
The secret to high-performance batteries lies in electrode consistency. Our dual-layer slot-die technology applies two distinct slurries with a perfectly defined interface. The immediately subsequent calendering process compacts this fresh coating under optimal conditions, resulting in electrodes with unparalleled density homogeneity and excellent adhesion to the current collector. This translates to higher energy density, longer cycle life, and lower internal resistance in your final cells.
3. “One-Pass” Efficiency Saves Space & Cost:
By integrating coating, drying, and calendering, we eliminate:
Multiple rewind/unwind stations.
Separate floor space for discrete machines.
Intermediate quality checks and handling that can damage wet electrodes.
This integration reduces your overall capital investment (CAPEX) and operational complexity, while improving overall yield.
