Semi-Automatic Winder for The Assembling of Single Cylindrical Cell - MSK-112A-EA

Please email for lead time
Item Number: MSK112A-EA
Transported by LTL Freight (Truck)
MSK-112A-EA is a semi-automatic winding machine for accurate assembly of single cylindrical cell cores (also known as “jelly roll”) of 18650, 21700 or 32650 cell. Using this machine, cathode and anode films, separated by the top and bottom separator films, are rolled up into a hollow cylinder casing for cylindrical battery applications. It is an ideal tool for the reliable and precise production of high-quality windings of electrode cores.


  • Color touchscreen control
  • Winding motor direction control: forward and reverse switchable (manual mode)
  • Adjustable tension (0 – 4 N) for both top and bottom separator films
  • Vacuum-assisted, 1200 mm long feeder bed for accurate cathode/anode film positioning & feeding
  • Automatic finish cut upon the completion of the configured number of rotations
  • Suitable for cylindrical battery sizes such as 18650, 21700, 26650 and 32650 (jelley roll dia. 14mm~32mm; length 25~70mm) 
Input Power
  • Single-phase, 220 VAC, 50 / 60 Hz
  • 1 kW power
Compressed Air

 pic1                pic2

  • Compressed air of 0.7 MPa is needed for the operation of this machine
  • Please note the air compressor is not included. Please click the picture below to order one at MTI, or order it from your local hardware store
  • Attention: If a gas cylinder is used instead of an air compressor(pic2), a two-stage pressure regulator(pic1) must be installed on the gas cylinder to limit the pressure within the required working range for safe operation. Click here to learn the installation of a gas regulator
Cathode / Anode Feeding
  • Loading material: cathode/anode sheets, such as aluminum foil coated with LiFePO4 or LiCoO2, NMC (cathode), and copper foil coated with graphite (anode)
  • Length range: < = 1200 mm recommended (length of the feeder bed plus extension)
  • Width range: 25 – 70 mm (adjustable on feeder bed)
  • Thickness range: 100 – 300 μm
Separator Feeding
  • Loading material: separator film rolls, such as polyethylene (PE) or polypropylene (PP)
  • Length range: separator roll with a diameter < 250 mm
  • Width range: 25 – 70 mm
  • Thickness range: < 100 μm
  • Tension range: 0 – 4 N for both top and bottom separator films

  • Winding needle size: 3.5 mm OD
  • Electrode winding size: 14 – 32 mm OD, 25 – 70 mm in length
  • To wind an electrode core with a certain OD, a spreadsheet for calculating the needed number of turns and electrode sheet length can be downloaded here
  • Winding speed: 0 – 400 rpm adjustable
  • Winding precision: < 0.5 mm edge roughness
Tape Dispenser

  • An automatic tape dispenser is included for strapping the finished electrode core with tapes
  • 220 VAC 50 / 60 Hz, 160 W
  • Cutting length range: 13 – 60 mm adjustable
  • Tape width range: 3 – 25 mm adjustable
  • Tape roll size: 25, 32, 75 mm ID, up to 130 mm OD
  • The tape dispenser manual is available for download here
  • 1000 mm L x 700 mm W x 900 mm H

Application Notes
  • Place the machine on a flat surface free of vibration to avoid tipping of the machine
  • Do not change the factory settings of air cylinders without consulting MTI. Beware not to change the air cylinder settings by accident.
  • Take extra caution when operating the cutter and motor to avoid possible physical injury! Do not touch the cutter with your hand! Do not put a hand close to the cutter while the equipment is operating! Do not let hand, hair, or cloth get caught in the rolling - clamping - winding assembly! Put up warning signs, and warn other people to stay clear of the equipment.
