• Ceramic coated on hardened tool steel with HRC > 72,
• The coating material: 97% is chromic oxide; 3% is aluminum oxide, calcium oxide, and magnesium oxide
• This roller is specially designed for rolling Lithium metal sheet, please don't use it for hard material

MSK-HRP-04-RD R2R system can be integrated with the calendering machine at extra cost to enable the automatic film unwinding -> winding after calendering. Please click underline to view product details.                                                                                                           

• CE Certificated
• All electric components ( >24V) are UL / MET / CSA certified
• NRTL(UL61010)  or CSA certification isavailable upon request at extra cost. (please click marks below for details)
•      

• One-year limited manufacturer warranty with lifetime support
• Rusting and damage due to improper storage condition or maintenance are not covered by warranty

• 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 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 roller gap (reference only)

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

• The rolling 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 calendering needed: While calendering the sample sheet, make each calendering decrement of 0.02mm comparing to sheet original thickness.
• Never calendering decrement over 0.02mm comparing to original sheet thickness each calendering.
• Must clean roller surface for each rolling and use acetone to clean and lubricate when not in use to avoid corrosion
• it is not allowed to use any MTI product in any hazardous location, especially prohibit from using in Class I environments (flammable gasses & vapor).
