Compact Vacuum Sealer with Integrated Control Unit for Preparing Pouch Battery - MSK-115A-S

Transported by LTL Freight (Truck)

Product Options

MSK-115A-S is a compact vacuum sealer for sealing the aluminum-laminated case for pouch cells in a glove box, which integrates temperature, pressure, and duration control into one unit for easy handling without feedthrough of the glovebox. The machine is compatible with both Argon and N2 gas.

MTI has granted the patent 201220296252.X for the Pouch Cell Sealing Machine MSK-115A-S since January 2013.

Sealing Pressure 

  • Pressue range: 0 ~ 7 kg/cm² adjustable. Vacuum chamber lid and sealing die need to be driven by compressed high purity inert gasses with recommended 60 psi pressure.
  • Consumption: ~ 0.1 L compressed air per sealing
  • Please use high purity inert gasses (Ar or N2), when operating in the glovebox. Using Air Compressor driven when operating outside the glove box.
  • Please note the air compressor is not included and not recommended to use in the glove box.
  • Attention: If a gas cylinder is used instead of 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.

Operation Manual & Video

Application Notes
  • Please wear gloves to operate the machine.
  • Beware of the automatic vacuum chamber lid. Only one operator is allowed for this equipment.
  • Please clean the sealing dies after each use. Clean the sealing die after it has cooled down to avoid corrosion by the electrolyte.
  • Check the level and smoothness of sealing die surface every week. If there is serious damage to the sealing die, please contact MTI to order a replacement.
  • Lubricate the cylinder every week
  • Check the screws in sealing dies and stage every month. Make sure they are tightened.
  • Compact design enables the operation inside the glove box with Ar atmosphere where Lithium SulfurLithium AirLithium Solid State or Li-ion half cell will be assembled. Please click the images below to understand these technologies and how it fits in a glove box.
