HRP-03RRL 8-Inch Roll-to-Roll Heating Calender for Multi-Layer Lamination up to 110°C with Alignment Control
The HRP-03RRL is engineered to facilitate precise roll-to-roll hot pressing and lamination of flexible electrode sheets, particularly for battery research applications involving solid lithium and flexible batteries. Its design accommodates both single-layer rolling and two-layer foil lamination, enabling efficient preparation of polymer- or soft-metal-based substrates.
This system features two 8-inch width feeding rollers and one winding roller, all equipped with tool-steel, chrome-plated surfaces hardened to HRC 60–62 for durability. The rollers can be heated independently up to 110°C for controlled thermal processing, with temperature accuracy maintained within ±2.5°C. The modular roll-to-roll assembly supports automatic tension control and optional alignment correction to ensure uniform lamination quality.

Typical Applications
The HRP-03RRL is ideal for preparing flexible electrode sheets used in solid-state lithium batteries and flexible battery research. It supports multi-layer lamination of polymer and soft-metal foils, enabling uniform pressing and thermal treatment essential for battery electrode fabrication.
Configuration & Operating Notes
The machine’s modular roll-to-roll assembly facilitates shipping and installation, including integration into dual-chamber gloveboxes with argon atmospheres. Proper alignment during installation is critical; optional alignment and rectifying control systems are available to enhance lamination precision during operation.
Users should avoid rolling materials harder than HRC 50 to prevent roller damage. Regular lubrication of roller bearings and cleaning of roller surfaces with acetone after use are recommended to maintain performance and prevent corrosion. Multi-step calendering with incremental thickness reduction (~0.02 mm per pass) is advised for optimal results.
