4" Width Electric Cold Roller Press with Optional Ceramic and PTFE Rollers-MSKMR100DC

MTI

MSK-HRP-MR100DC is a UL/CSA ready electric rolling press with variable speed 24VDC gear motor and UL certified switch power supply, which can be used from 110V- 220VAC under Argon gas glovebox. It has dual rollers of 100 mm Dia. x 100mm width and is an ideal rolling press for preparing electrode sheets for Li-Ion batteries research after coating and drying. (Since 11/29/2016, MR100DC ceramic coated roller option is available.)


SPECIFICATIONS:

Working Voltage
  • 110V - 240V AC, 50/60Hz, worldwide use
  • UL/CSA/TUV certified power supply is in the outside machine for easy

  • Roller diameter tolerance (TIR): <0.004mm
  • RA (Roughness Average): 0.4um
  • Never roll materials with hardness > 50HRC (benchtop rolling press is not suitable for calendering thick metals. For applications with such needs, please consult with MTI engineers.)
  • Optional Rollers: Ceramically coated rollers are available in the product option bar
    • Ceramic coated on hardened tool steel with HRC > 72,
      • The coating material: 97% is chromic oxide; 3% is Al2O3, CaO3, and MgO
      • This roller is specially designed for rolling Lithium metal sheets,
    • PETE rollers? Good for laminating Lithium foil with Copper foil
Roll to Roll System (Not included)
Compact Roll to Roll System for R2R Calendering or Coating Machines upto 8" Width - MSK-HRP-04-RD

R2R device can be integrated with the calendaring machine at extra cost to enable the automatic film unwinding -> winding after calendaring. Please click underline to view product details.
Compliance
  • CE Certificated
  • NRTL(UL61010) or CSA certification is available upon request at an extra cost
Application Notes
  • MSK-MR100DC roller can be used under Ar or N2 gas glove-box
  • Must use acetone to clean and dry rollers' surfaces after each use to avoid rusting
  • Apply anti-rust lubricant on roller surface if the machine were to be unused for a long period of time
  • Never rolls materials with hardness > 50HRC
  • Min. thickness for each rolling is dependent on the materials. Here are some results from our test:
  • Please refer to this instruction on how to calculate rolling pressure from the 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

Warnings
  • The machine is not designed for thick metallic material. Click pic left for the rolling machine for metal
  • In order to prolong the lifespan of the roller bearings, regular lubrication is recommended
  • Multi-step thickness calendaring needed: While calendaring the sample sheet, make each calendaring decrement of 0.02mm compared to the sheet original thickness
  • Never calendaring decrement over 0.02mm compared to original sheet thickness each calendaring.
  • Must clean roller surface after each rolling and lubricate when not in use 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)
