Products Description
The XW-H400450-CT is a specialized hydraulic heating calendering machine designed for lithium-ion battery electrode manufacturing. This advanced equipment integrates precise calendering, thermal processing, and compaction functions to optimize electrode sheet production. Utilizing a robust hydraulic system for pressure application and an integrated heating mechanism for roller temperature control, the machine processes coated electrode sheets through the synchronized operation of its upper and lower rollers. This sophisticated system ensures the production of electrode sheets with precisely controlled thickness and density, while simultaneously enhancing both electrical conductivity and structural integrity, ultimately improving battery performance characteristics.
