MSK-HRP-04C-PTFE 8-Inch PTFE Rolling Press with Digital Pressure Display for Precise Lithium Electrode Lamination
The MSK-HRP-04C-PTFE is engineered to meet the demanding requirements of calendaring thin lithium battery electrodes and delicate soft metal foils. This desktop rolling press enables precise control over thickness and surface quality by applying uniform pressure and heat during lamination processes. Its design is optimized for materials that require gentle handling and accurate thickness reduction without damage.
The press incorporates two 8-inch diameter rollers made of high-quality PTFE, each independently heated and regulated by PID controllers to maintain consistent temperatures up to 200°C. This dual temperature control ensures uniform heating across the roller width, critical for achieving consistent calendaring results. The pressing force is monitored in real time by an integrated load cell, with digital display in kilograms-force, allowing operators to precisely adjust pressure according to material properties and desired thickness.
Key Features
- Effective calendaring width of 200 mm (8 inches) suitable for electrode sheets and foils.
- Rollers constructed from PTFE with dimensions 96 mm diameter by 220 mm width for smooth, non-stick surface.
- Adjustable roller gap from 0 to 2 mm with ±0.01 mm precision and thickness indication accuracy of 0.001 mm.
- Digital pressure display via integrated load cell measuring up to 2 tons force (displayed in Kgf).
- High torque 24 V DC motor with 1:75 gear reduction, providing adjustable rolling speed from 5 to 45 rpm.
- Dual PID temperature controllers for independent roller heating up to 200°C ensuring uniform thermal conditions.
- Digital micrometers included for precise thickness measurement, replacing mechanical micrometers since 2020.

Typical Applications
This rolling press is ideal for calendaring lithium battery electrodes to improve density and surface finish, processing plastic media films, and laminating soft metal foils such as copper, silver, or gold coatings. It is commonly used in battery research and development labs for electrode fabrication and quality control.
Configuration & Operating Notes
The standard package includes digital micrometers for precise thickness measurement. Optional integration with an MSK-HRP-04-RD roll-to-roll system is available for automated film unwinding and winding. A vertical version can be requested for specialized applications.
Operators should avoid touching heated rollers during operation and perform multi-step thickness reductions not exceeding 0.02 mm per pass to prevent damage. Cleaning rollers with acetone after use is recommended to maintain surface quality and prevent corrosion. This press is not suitable for calendaring materials harder than 30 HRC or thick metals.
