HRP-03RRL 8-Inch Roll-to-Roll Heating Calender for Multi-Layer Laminating up to 110°C with Alignment Control
The HRP-03RRL is engineered to facilitate precise roll-to-roll hot rolling 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. The rollers incorporate central heating elements allowing operation up to 110°C, with continuous use recommended below 100°C to maintain roller integrity. The modular roll-to-roll assembly supports installation in controlled environments such as dual-chamber gloveboxes, with electrical components compatible with argon atmospheres.
Key Features
- Two 8″ feeding rollers and one winding roller with automatic tension control for consistent material feed.
- Heatable rollers with independent temperature controllers, maintaining accuracy within ±2.5°C.
- Adjustable pressing thickness up to 2 mm with dial gauge precision of 0.01 mm.
- Roller surface hardness HRC 60–62; suitable only for materials below HRC 50 hardness.
- Maximum rolling speed of 5.92 RPM and linear speed up to 60 mm/sec.
- Optional alignment and rectifying control systems to enhance lamination uniformity.
- Modular design for ease of shipping and installation, compatible with glovebox environments.

Typical Applications
Ideal for preparing flexible electrode sheets used in solid-state lithium and flexible battery research. Suitable for lamination of polymer and soft-metal foils requiring controlled heating and precise thickness adjustment. Compatible with glovebox environments for inert atmosphere processing.
Configuration & Operating Notes
The machine consists of three modular sections for feeding, rolling, and winding, facilitating installation and maintenance. Proper alignment during setup is critical, especially when using the optional alignment control system. The rollers must not be used with materials harder than HRC 50 to avoid damage. Regular lubrication of roller bearings and cleaning with acetone after use are recommended to maintain performance and prevent corrosion. Multi-step thickness reduction is advised, with approximately 0.02 mm reduction per pass.
