Description
Degassing Vacuum Sealing Machine – Pouch Battery Vacuum Sealer with Puncture & Degas Function
This Degassing Vacuum Sealing Machine is a specialized equipment designed for vacuum extraction and hot-press sealing of pouch lithium batteries after the liquid injection and static rest stages. It combines air bag puncture, vacuum degassing, and hermetic sealing in a single automated cycle, ensuring optimal battery performance and safety.
Working Principle:
- The upper and lower chambers form a sealed cavity around the battery.
- A lancet punctures the air bag to release trapped gases.
- Vacuum extraction creates a negative pressure state within the cavity (down to -90KPa).
- When the set vacuum level is reached, the heated sealing head applies thermal energy to the aluminum-plastic film.
- The film softens and fuses together, creating a hermetic seal after degassing.
Key Features:
- Integrated Degassing & Sealing: Combines air bag puncture, vacuum extraction, and heat sealing in one process.
- Precision Temperature Control: Brass sealing heads provide excellent thermal conduction; temperature adjustable up to 200°C (recommended 180°C).
- Adjustable Vacuum Level: Vacuum degree adjustable, with maximum ≤ -90KPa.
- Flexible Sealing Parameters: Sealing time 0–99s adjustable (recommended 3–6s); edge width customizable.
- Pressure Adjustment: Sealing head pressure adjustable via pressure regulating valve for different process requirements.
- Smooth Operation: Cylinder-driven sealing head with linear guide sleeve ensures flexible movement and precise parallelism.
- Waste Liquid Recovery: Integrated system for safe collection of any expelled electrolyte.
- Glove Box Compatible: Compact design suitable for use inside argon/nitrogen glove boxes.
Applications:
- Degassing and final sealing of pouch lithium batteries after electrolyte filling
- Battery R&D laboratories
- Small-batch production of soft-pack batteries
- Glove box-based battery assembly
