MSK-115A-H Large Vacuum Sealer with Electrolyte Injection and Vacuum Standing for Pouch Cells up to 500×350 mm
The MSK-115A-H is engineered to address the complex requirements of assembling large or mid-size pouch cell batteries, commonly used in electric vehicles. This multifunctional equipment combines vacuum sealing, electrolyte injection, and vacuum standing processes into a single integrated system, enabling precise control over electrolyte filling and enhanced electrode immersion under controlled vacuum conditions.
Designed for operation within dry room environments, the MSK-115A-H maintains a dry inert atmosphere using continuous purging with high purity inert gas (preferably argon). This ensures minimal moisture contamination during electrolyte injection and vacuum standing phases. The system includes a built-in liquid electrolyte filtration and vacuum pump, supporting high-precision dispensing with an injection accuracy of 0.3%. Electrolyte volume and injection rate are adjustable through a touch screen PLC interface.
Key Features
- Three-in-one design integrating vacuum sealing, electrolyte injection, and vacuum standing for pouch cells.
- Supports pouch cells up to 500 mm length, 350 mm width, and 20 mm height, including multi-cell sealing configurations.
- Electrolyte injection pump with speed control and filtration system for precise and clean dispensing.
- Adjustable vacuum range from -95 to 0 kPa and dwell time up to 99 seconds for optimized degassing and electrolyte diffusion.

Typical Applications
The MSK-115A-H is ideal for research and development or small-scale production of large pouch cells used in electric vehicles and advanced battery technologies. It supports assembly processes requiring precise electrolyte filling and high-quality vacuum sealing under inert atmospheres, suitable for lithium-ion, lithium-sulfur, lithium-air, and solid-state battery cells.
Configuration & Operating Notes
The system includes a plunger metering pump for electrolyte injection and a vacuum pump integrated with a liquid electrolyte filtration system. Operators should regularly clean the sealing dies after cooling to prevent corrosion from electrolyte residues and inspect the sealing surface for damage. Replacement sealing dies can be ordered if wear or damage occurs. The equipment can be optionally equipped with a programmable gas purge function to enhance inert atmosphere maintenance during operation.
