Lab-scale calendering for process validation
IMC lab calenders deliver production-grade compression precision in compact and pilot-scale formats. These systems are designed for process development, material qualification, and sample production — generating calendering data that transfers reliably to production scale.
The platform is a two-roll single nip calender; the table below covers the standard configuration and options.
Available features
Non-contact thickness gauging before and after the nip, real-time force measurement, temperature profiling, speed control with precise ramp capability, and full data acquisition for process analysis. Recipe management stores validated parameters for reproducible sample production.

Lab trial services
Bring your coated electrode samples, PTFE sheets, or specialty materials to our Birmingham laboratory. Our engineers will work with you to establish calendering parameters, evaluate thickness and density results, and generate the process data needed for production equipment specification.
