0.0/5 rating (0 votes)


EQ-MSK-700C is customized and manually operated large cup forming machine with Max/  600 x 600 mm pouch die , which is designed for making large pouch cell in battery research lab.  
MSK-115A-L is a larger vacuum sealer that does the final sealing for aluminum-laminated battery after electrolyte injection and cell formation. A pouch piercing needle and heatable sealing blade are built into the vacuum chamber. With the advanced pouch auto piercing feature, the battery's final sealing (de-gassing and pouch resealing) can be automatically completed under vacuum conditions. 
Update 01/09/2020: The Spring-loaded pressure board is now made with aluminum. An additional tilting setting has been included in the bottom board - it may now be flat or tilted up.


Operation Flowchart: Chamber Evacuation/vacuum -> Needle Down -> Pierce the Excess Area of the Pouch -> Needle Up -> De-gas the Pouch -> Heat-Sealing -> Release to atmospheric pressure
Working Voltage AC110V or 220V, 50/60Hz (please select the voltage in the options menu)
Power 600W
Working Area

  • Refer to the Standard sealing area pic below to find out the maximum size of the battery pouch that can be placed in the working area.
  • Updated 01/09/2020: The bottom working area will be flat or tilted by a single button on the side. Please look at the pictures below
Spring Loaded Pressure Board

  • Equips with a Spring Loaded Pressure Board to push air out of the pouch cell before vacuuming

Vacuum Level
Sealing Blade Dimension 340mm x 8mm
Heating Timer 0 - 99 seconds Adjustable
Sealing Temperature 50 - 250°C adjustable with control accuracy of +/-2°C
Suggested Air Pressure
  • The vacuum chamber lid and sealing die are driven by compressed air
  • Input air pressure: 90 psi (0.6 Mpa). System working air pressure: 80 psi (0.55 Mpa)
  • Air compressors and fittings are not includedplease click here to order or order from your local hardware store
