MSK-HRP-04B 8-Inch Width Hot Rolling Press with Dual PID Temperature Control and Digital Pressure Display
The MSK-HRP-04B is engineered for laboratory-scale calendaring tasks requiring precise control over temperature and pressure. It is particularly suited for densifying battery electrodes, plastic media, and soft metal foils to improve surface quality and material density. This desktop rolling press accommodates materials up to 8 inches (200 mm) wide and can reach temperatures up to 200°C, enabling controlled thermal processing during rolling.
The machine employs two high-strength hardened steel rollers, each independently heated and regulated by separate PID controllers. This dual temperature control ensures uniform heating across the rollers, enhancing process consistency. The compression force applied during calendaring is monitored in real time via an integrated load cell, with the pressure displayed digitally on the control box for operator feedback.
Key Features
- Effective calendaring width of 200 mm (8 inches) with rollers plated in chromium for corrosion resistance.
- Roller material is high-strength hardened steel with hardness RC > 52; not suitable for materials harder than RC 45.
- Dual PID temperature controllers with 30 programmable segments each, allowing independent roller temperature control up to 200°C.
- Digital micrometers included for precise thickness measurement with 0.004 mm accuracy over a 0–12.7 mm range.
- Integrated load cell provides digital display of compression force up to 2 tons (Kgf units).
- Adjustable roller gap from 0 to 2 mm with ±0.01 mm precision.
- High torque 24 VDC motor with reducing gear enables adjustable rolling speed up to 40 mm/s real linear speed.

Typical Applications
This rolling press is ideal for laboratory processing of battery electrodes to increase density and improve surface uniformity. It is also suitable for calendaring plastic films and soft metal foils such as silver or gold coatings. The machine supports precise thickness reduction with minimal variation, enabling research and development in advanced material fabrication.
Configuration & Operating Notes
The standard package includes two digital micrometers replacing previous mechanical versions for improved accuracy. Optional accessories include an MSK-HRP-04-RD roll-to-roll system for continuous processing, a vertical machine configuration, and computer data recording with program storage capabilities. Users should avoid calendaring materials with hardness above RC 45 and limit thickness reduction increments to 0.02 mm per pass to prevent damage. Roller surfaces require regular cleaning and acetone lubrication when idle to prevent corrosion. The machine is compatible with argon gas glove box environments.
