High-Precision Calendering & Slitting System

The machine is designed for next-generation electrode manufacturing in solid-state, lithium-ion, and advanced energy storage applications. It enables simultaneous double-sided dry coating and current collector integration in a single step, bridging R&D with scalable pilot production. Key Features Double-Sided Coating – Uniform active layers on both sides with strong interfacial bonding. Flexible Roll Setup – Supports 10–20 rolls (Φ150–500 mm, width ≤1000 mm). High-Speed & Stable – Coating speeds up to 50 m/min with quick roll changeover. Precision Control – Film thickness down to 50 µm, width up to 800 mm; auto edge-trimming & web-guiding Heating Options – Electric or thermal oil systems for consistent temperature control. Advantages All-in-One Process – Coating, lamination, and integration in one step. High Alignment & Winding Quality – Ensures neat, reliable electrodes for downstream assembly. Scalable & Reliable – Ideal for pilot and small-batch production. Easy Maintenance – Fast roll swaps and simplified cleaning.
