MSK-HRP-01 Heated Dual-Roller Calendering Press

Overview

The MSK-HRP-01 Heated Dual-Roller Calendering Press is an engineered laboratory-scale calender system designed for controlled mechanical densification and thickness reduction of thin-film electrode materials—particularly cathode and anode composites used in lithium-ion battery R&D. Unlike conventional cold-rolling equipment, the MSK-HRP-01 integrates precision resistive heating directly into the roller assembly, enabling thermomechanical processing under defined thermal conditions. Its operation relies on symmetrical counter-rotation of two hardened steel rollers with adjustable gap geometry, applying uniform compressive stress across the material web while maintaining dimensional stability up to 80 °C continuously (100 °C for short-duration cycles). This architecture supports fundamental studies on particle rearrangement, binder redistribution, pore structure evolution, and interfacial adhesion under coupled thermal–mechanical loading—key parameters influencing ionic conductivity, electronic percolation, and cycle life in next-generation energy storage devices.

Key Features

• Integrated roller-heating system with independent temperature regulation (0–100 °C), calibrated to ±1 °C accuracy via PID-controlled solid-state relay and embedded PT100 sensor
• Twin high-hardness alloy steel rollers (≥900 HV) with ground surfaces (Ra ≤0.4 µm) and axial runout ≤0.004 mm—ensuring uniform pressure distribution and minimal edge thinning
• Digital linear speed controller (5–35 mm/s) with real-time LED display and fine-tuning capability for reproducible strain-rate application
• Micrometer-adjustable gap mechanism with 0.01 mm resolution and locking screw—enabling precise thickness targeting from initial composite films (~100 µm) down to final electrode densities ≥2.8 g/cm³
• Modular mechanical design compliant with CE safety directives, including insulated housing, emergency stop circuit, and overtemperature cutoff at 110 °C
• Low thermal inertia heating profile optimized for rapid stabilization (≤15 min to reach 80 °C), minimizing thermal lag during sequential calendering passes

Sample Compatibility & Compliance

The MSK-HRP-01 accommodates free-standing slurry-cast or dry-powder laminated films up to 2 mm thick and 90 mm wide, including NMC, LFP, silicon-carbon composites, conductive polymer blends, and noble metal foils (Au, Ag, Cu, Al). It is routinely deployed in academic labs and industrial pilot lines adhering to ISO/IEC 17025-compliant quality systems. While not a GMP-certified production tool, its CE marking confirms conformity with EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. Temperature logging functionality (via optional external data logger) supports GLP-aligned documentation for method validation studies referenced in ASTM D790 (flexural properties) and IEC 62660-1 (secondary lithium cell testing protocols).

Software & Data Management

The MSK-HRP-01 operates as a standalone electromechanical instrument without embedded firmware or proprietary software. All operational parameters—including roller speed, gap setting, and heater setpoint—are manually configured using front-panel controls. For traceability, users integrate third-party digital multimeters (e.g., Keysight 34465A) or thermocouple data loggers (e.g., Omega OM-DAQPRO-5300) to record time-stamped temperature, speed, and position data. The system supports audit-ready documentation when paired with laboratory information management systems (LIMS) that comply with FDA 21 CFR Part 11 requirements for electronic records and signatures—provided user-defined metadata (operator ID, batch number, pass count) is entered externally.

Applications

• Electrode densification optimization for Li-ion, solid-state, and Na-ion battery prototypes
• Thickness calibration of freestanding separator membranes prior to cell assembly
• Controlled lamination of bilayer or gradient electrodes to study interlayer diffusion kinetics
• Mechanical property screening of flexible conductive inks and printed electronics substrates
• Pre-compaction of powder metallurgy green bodies for sintering yield analysis
• Thermomechanical aging studies of polymer-based composite films under constrained deformation

FAQ

What is the maximum continuous operating temperature for stable gap control?
Continuous operation is rated at ≤80 °C. At 100 °C, thermal expansion may cause transient gap drift (>0.02 mm); therefore, this temperature is limited to ≤60 min per session.
Can the MSK-HRP-01 process aqueous-based slurries directly?
No. The rollers are not sealed against moisture ingress. Samples must be pre-dried to <5% residual solvent content to prevent steam-induced delamination or roller corrosion.
Is the gap adjustment mechanism repeatable after thermal cycling?
Yes—micrometer feed screws maintain positional memory across thermal cycles when calibrated at ambient temperature before each test series.
Does the unit include temperature ramp profiling capability?
No. Ramp rate is fixed at ~1.3 °C/min from ambient to 100 °C. Custom profiles require external programmable power supplies and thermocouple feedback loops.
What maintenance intervals are recommended for roller surface integrity?
Visual inspection and surface roughness verification (per ISO 4287) every 200 operating hours; regrinding advised if Ra exceeds 0.6 µm or hardness drops below 850 HV.
