100C Max. 4" Width Electric Hot Rolling Press with Variable Speed (Ar Gas Compatible) - MSK-HRP-01

0.0/5 rating (0 votes)


MSK-HRP-01 is a compact Hot Rolling Cylinder Press with max. working temperature of 100°C, which is designed for preparing battery electrode for both inside or outside a glove-box. High torque DC motor is Ar gas compatible. It serves well in the application such as increasing active material density of the electrode in Li-ion batteries research after coating. It has a pair of 100mm width steel rollers with a maximum heating capacity of 100°C.
Update Note: Since 11/25/2015, MSK-HRP-01 is equipped with 24V DC motor for safe operation under Ar gas environment.

Application Notes

Important announcement (please read this before place the order)

  • The MSK-HRP-01 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
  • This rolling press can be used to make free-standing 2D metal nanosheets by a repeated process of folding and calendering stacked metal sheets (See reference below)
  •  Reference Articles: 2D Metals by Repeated Size Reduction

Compliance & Warranty
  • CE Certified
  • MET certificate is available upon request at an 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          
Operation Video            Guage Calibration Video         Cleaning Instruction
  • Do not touch the surface of the rolling part of the machine when the rollers are heated up or running.
  • Due to the influence of working environments, the temperature on the roller surface may be different from the display on the controller. You may calibrate the temperature by EQ-TC-calibrator-LD, and refer to the instruction here from time to time to ensure heating temperature accuracy
  • Never roll materials with hardness > 50HRC
  • Multi-step thickness calendering needed: While calendering the sample sheet, make each calendering decrement of 0.02mm comparing with sheet original thickness.
  • Never calendering decrement over 0.02mmcomparing with original sheet thickness each calendering.
  • Heating the cylinder beyond 100ºC results in roller deformation and causes inaccurate, thicker-than-usual rolling yield.
  • In order to prolong the lifespan of the roller bearings, regular lubrication is recommended. 
  • Clean roller surface for each rolling  and Use acetone to clean and lubricate  when not in use to avoid corrosion
  • This rolling machine can be used under Ar gas
  • It is not allowed to use any MTI product in any hazardous location, especially prohibit from using in Class I environments (flammable gasses & vapor).
