HRP-300 Hydraulic Rolling Press Machine

High-Precision Electrode Calendering for Battery R&D

The HRP-300 Hydraulic Rolling Press Machine is designed for controlled calendering (rolling densification) of battery electrodes after coating and drying. During operation, a coated current collector (e.g., Al or Cu foil) passes through two precision rollers. Hydraulic pressure and an adjustable roller gap compress the electrode layer to improve particle–particle contact, reduce porosity to a targeted level, and enhance thickness uniformity—key factors for repeatable electrochemical performance and reliable cell-to-cell consistency.

Key Features & Technical Highlights

• Effective rolling width: 300 mm (supports research and pilot-scale electrode sheets)
• Adjustable line speed: 0.3–4 m/min (enables optimisation for different slurry systems and loadings)
• Rolling press gap: 0–3 mm adjustable (for anodes, cathodes, and coated foils)
• Electrode thickness / uniformity control: high-precision control with ±0.002 mm uniformity capability (application dependent)
• Max working pressure: ~40 tonnes total hydraulic force
• Roller size: Ø196 × 330 mm (diameter × roller width)
• Electrical: AC 380 V, 50/60 Hz; 2000 W
• Footprint / mass: ~1400 × 500 × 1300 mm; ~550 kg
  
  

Compatibility & Typical Use Cases

This calender is commonly used with lithium-ion electrode preparation workflows and pairs well with upstream/downstream tools such as coaters, slitters, dryers, and battery cyclers. It is suitable for:

• Cathode/anode densification and thickness tuning
• Improving adhesion and reducing cracking risk (process dependent)
• Producing consistent electrodes for coin, pouch, or cylindrical cell fabrication
