HRP-03RRL is a 8" width roll-to-roll hot rolling press by modular design for either hot rolling one layer or laminating two-layer of foil materials together. The rollers can be heated up to 110°C during the roll-to-roll processing. It is designed for preparing polymer or soft metal-based flexible electrode sheets for battery research, especially for solid Lithium or flexible battery.

|
| Application Notes |
- Never roll materials with hardness > 50HRC
- In order to prolong the lifespan of the roller bearings, regular lubrication is recommended
- Multi-step thickness calendering needed: While calendering the sample sheet, make each calendering decrement of 0.02mm compared to the sheet original thickness
- Clean the roller surface for each rolling and Use acetone to clean and lubricate when not in use to avoid corrosion
