Roll to Roll Heating Calender (8

Roll to Roll Heating Calender (8" W) up to 110C for Multi-layer Laminating - HRP-03RRL

0.0/5 rating (0 votes)


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
