8" Width PTFE Rolling Press w/ Digital Pressure Display for Lithium Lamination - MSK-HRP-04C-PTFE

MTI

MSK-HRP-04B is a desktop rolling press with a maximum working temperature up to 200°C.The temperature of two 8'' wide rollers is individually controlled by two PID temperature controllers to achieve better heating uniformity and control accuracy. The compression pressure force can be measured by the integrated load cell and displayed on the control box during the process. It is an ideal tool for calendaring battery electrodes, plastic media, and soft metal foils. Typical usage is to increase material density and achieve better surface quality. 
Note: Since 12/18/2020, Digital Micrometers are included in the standard package instead of Mechanical Micrometers.

SPECIFICATIONS:

Effective Calendaring Width
  • 200 mm
Roller Material & Size
  • Rollers are made of high-quality PTFE
  • Size: 96 mm Dia. x 220mm W
  • Roll line speed: 0~26mm/s adjustable
  • Note: benchtop rolling press is not suitable for calendering thick metals. For applications with such needs, please consult with MTI engineers

Roller Gap
  • 0~2 mm ± 0.01 mm adjustable, 
Dial Gauge Accuracy
(Thickness Indicating)
  • 0.001mm
     

Pressure Force Indication
  • 0~2T (the unit display is Kgf) 
  • (Note: the actual calendaring force is dependent on the material physical properties such as hardness and thickness. The rolling gap thickness will also affect the applied force.) 

Power

Motor (Ar Gas Glove Box Compatible)
  • High torque 24VDC motor with reducing gear (1:75) 
  • Motor power: 40W
  • Rolling speed adjustable: 5~45 r/min
  • Digital control with constant output power 

Output 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
  • Thickness uniformity: +/- 2 microns if coating electrode thickness +/- 5 micron and each rolling increased < 10 microns

 Optional 
  • MSK-HRP-04-RD R2R system can be integrated with the calendaring machine at extra cost to enable the automatic film unwinding -> winding after calendaring.(Pic. 1-3) 
  • The vertical version is available upon request at an extra cost (Pic.4)
          Pic. 1         Pic. 2       Pic. 3  Pic. 4

Compliance 
  • CE Certified
  • NRTL or CSA certification is available upon request at extra cost.
Warnings
  • Do not touch the surface of the rolling part of the machine when the rollers are heated up or running.
  • Multi-step thickness calendering needed: While calendering the sample sheet, make each calendering decrement of 0.02mm compared with the sheet's original thickness.   
  • Never calendaring decrement over 0.02mm. Never roll materials with hardness > 30HRC
  • Clean roller surface for each rolling  and Use acetone to clean and lubricate  when not in use to avoid corrosion
