200C Max 4"W Vertical Hot Rolling Press w/ Dual Temperature Control (Ar Gas compatible) - MSK-HRP-02

0.0/5 rating (0 votes)


MSK-HRP-02 Vertical Hot Rolling Press features a pair of 100mm wide steel rollers with independent temperature control up to 200°C. Its vertical rolling position allows users to "gravity feed" flexible films/tapes. Such a compact calendar  machine can be put in Ar gas glove-box and very useful for preparing flexible battery electrode sheet for Li-ion / Soli Metal-Air battery research

Dial Gauge Accuracy

Minimum Thickness
Depending on the electrode's material and thickness, typically:
  • A 0.16mm thick electrode coated on copper can be pressed into a minimum thickness of  0.1 mm
  • A 0.06mm thick electrode coated on copper can be pressed into a minimum thickness of 0.04 mm
  • A 0.33mm thick silver/gold can be pressed into a minimum thickness of 0.03 mm
Temperature Control
  • Two independent temperature controllers enable dual-zone temperature control for the front and rear rollers.
  • Temperature range: RT - 200°C
  • Temperature accuracy +/-5°C
  • Max heating temp: 200°C < 1.5 hour
  • Continuous heating temp: 190°C
  • Two heating elements are installed
  • Power of each Heating Element: 500 Watts
  • The heating rod is aconsumable. Please click picture left to order replacment
Heating Rate
  • RT-100°C: ~3°C/min
  • 100-150°C: ~2.5°C/min
  • 150-200°C: 1~2°C/min
Gravity-Feed Design
  • Two rollers are aligned horizontally and supported by the steel frame. Such a design allows users to gravity-feed flexible materials front above the rollers and collects at the bottom. (Pic. 1)
  • Independent speed control is available upon request at the extra cost. (Pic. 2)

Application Notes

Important announcement (please read this before place the order)

  • The MSK-HRP-02 roller is specially designed for battery R&D in terms of its advantages as affordable, compact, and precise. Please strictly follow the instructions to operate
  • Must use acetone to clean rollers' surface after each use
  • Never rolling material with hardness > 50HRC
  • If the machine will be idle for a long period of time, please apply anti-rust lubricant on the rollers
  • The minimum thickness of the rolled sheet should depend on the physical property of the material. Here are some results from our test:
  • Please refer to this instruction on how to calculate rolling pressure from roller gap (reference only)
Electrode  Size    Original thickness    Finished thickness   
LiFePO4 double sides 50mm Width x 260mm Length    0.205mm 0.09mm
LiMn2O4 double sides 50mm Width x 260mm Length 0.205mm 0.09mm
Copper foil + graphite (single side) 75mm Width x 240mm Length 0.09mm 0.04mm

Compliance & Warranty
  • CE Certified
  • NRTL or CSA certificate is available upon request at extra cost.
  • One year limited warranty with lifetime support
  • Rusting and damage due to improper storage condition or maintenance are not covered by warranty
Operation Instructions          
  • Never roll materials with hardness > 50HRC
  • The rolling machine can be used in the Ar gas environment.
  • 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 with the sheet original thickness.
  • Never calendering decrement over 0.02mm comparing with original sheet thickness each calendering.
  • Clean the roller surface before and after each rolling process. Lubricate the roller surface when the machine is planned for idle to avoid corrosion.
  • It is not allowed to use any MTI product in any hazardous location, especially prohibited from using in Class I environments (flammable gasses & vapor).
