MSK-2150-PD 4T Max Gap-Control Cold Rolling Press with Digital Pressure Display and Roll-to-Roll Option for Battery Electrode Calendaring
The MSK-2150-PD is engineered to meet the demanding requirements of lithium-ion battery research, specifically for adjusting electrode thickness and material density after coating and drying processes. Its compact design integrates a gap-control mechanism with a digital pressure display, enabling precise calendaring of thin films and electrode sheets up to 150 mm (6″) wide.
This electric rolling press supports both standalone operation and roll-to-roll (R2R) processing, with the R2R device being removable for flexible use. The machine is optimized for delicate materials, providing controlled rolling pressure and speed to avoid damage while ensuring uniform thickness and density.
Key Features
- Maximum rolling pressure of 4 tons, digitally displayed in real time for precise control.
- Dual hardened steel rollers (150 mm width × 94 mm diameter) with chromium electroplated coating and surface hardness HRC 58–62.
- Adjustable rolling speed from 10 to 50 mm/second with forward, stop, and backward controls.
- Dual micrometer system for accurate gap adjustment within 0 to 3 mm range, resolution 0.01 mm.
- Removable roll-to-roll system enabling automatic film unwinding and winding during calendaring.
- Heavy-duty steel frame and gears designed for durability and stable operation.
- Digital micrometer with interchangeable units (mm/in), zeroing function, and battery-powered display.

Typical Applications
The MSK-2150-PD is primarily used in lithium-ion battery research laboratories for calendaring electrode sheets to achieve uniform thickness and density. It is suitable for processing coated and dried electrode materials, thin films, and other delicate substrates requiring precise mechanical compression. The roll-to-roll option facilitates continuous film processing for research-scale production and testing.
Configuration & Operating Notes
- The roll-to-roll device is removable, allowing the press to be used as a standalone rolling machine.
- Do not use the machine inside glove boxes with argon gas atmosphere.
- Materials with hardness exceeding 50 HRC must not be rolled to avoid damage to rollers.
- For multi-step thickness reduction, limit each decrement to no more than 0.02 mm compared to the original sheet thickness.
- Clean roller surfaces with acetone after each use and apply anti-rust lubricant if the machine will be idle for extended periods.
- The digital micrometer is battery powered (CR2032 3V) and allows zeroing and unit switching between mm and inches.
- Consult technical support for processing thick metals or materials outside typical battery electrode parameters.
