Precision calender machines for demanding compression applications
Calender machines are one of IMC's core specialties. These robust machines combine extremely high compression capability with the precision required for battery electrode densification, PTFE processing, filtration media, and specialty materials. Sizes range from tabletop lab units to high-speed, fully automated production systems, with roll options to match the pressure profile the product needs — including crowned and deflection-compensated rolls for uniform compression across the full face.
Calender technologies
Single nip calenders
Two-roll compression with precision gap control, heated rolls, and high nip force capability for electrode densification.
Multi nip calenders
Multiple-roll configurations for progressive compression, surface finishing, and multi-stage processing in a single pass.
Heated roll calenders
Uniformly heated rolls with precision temperature control for thermal compression, embossing, and thermoplastic processing.
Lab calenders
Benchtop compression and densification for material testing and initial process development.
Pilot calenders
300 mm+ web at up to 136 metric tons — production-relevant densification with heated rolls and closed-loop gap.
Powder mill calenders
Dry-process powder-to-film formation and lamination for solvent-free electrode manufacturing — IMC has worked with dry powder battery processing from the beginning.
