5 In 1 Sealing Machine（Split）

5 In 1 Sealing Machine (Split) – Pouch Cell Top/Side Sealing, Electrolyte Filling & Vacuum Sealin

This 5 In 1 Sealing Machine (Split) is a comprehensive solution designed to meet the production requirements for pouch lithium batteries. It integrates five essential functions into a single, compact system: top sealing, side sealing, first-stage vacuum sealing, electrolyte filling, and vacuum standing. The split design allows flexible placement, with the main unit suitable for glove box operation.

Machine Sections & Functions:

1. Top and Side Sealing Section

This section handles both top and side sealing without requiring a head change. Resistance heating elements transfer heat to the brass sealing head, which then applies thermal energy to the aluminum-laminated film. Under controlled pressure, the film softens to a near-molten state, achieving reliable bonding and sealing.

2. Electrolyte Filling and Vacuum Standing Section (Filling Pump Optional)

Operators place batteries vertically in fixtures for electrolyte filling. A precision pump (optional) dispenses accurate electrolyte volumes. After filling, the operator manually closes the pressing plate, forming a sealed chamber with the lower cavity. The equipment then creates a vacuum environment for standing, with programmable duration up to 99.99 seconds.

3. First-Stage Vacuum Sealing Section (Vacuum Pump Optional)

This section forms a sealed chamber between upper and lower cavities. The system evacuates the chamber to achieve negative pressure. Simultaneously, the heated sealing head softens the aluminum-laminated film to create a hermetic seal under vacuum conditions.

Key Features:

• Five Functions in One: Combines top sealing, side sealing, electrolyte filling, vacuum standing, and first-stage vacuum sealing.
• Split Design: Main unit fits inside glove boxes; electric cabinet remains outside for space efficiency.
• Precision Temperature Control: Adjustable up to 200°C with recommended 180°C for optimal sealing.
• High Vacuum Capability: Reaches ≤-90KPa for effective degassing and sealing.
• Flexible Sealing Parameters: Time adjustable 0–99 seconds, edge width customizable.
• Large Capacity: Accommodates batteries up to L180×W180×H10mm (including air bag and tabs).
• Dual Gas Compatibility: Operates with argon/nitrogen inside glove boxes or compressed air outside.
• User-Friendly Controls: Intuitive interface for setting temperature, time, vacuum, and standing duration.

Applications:

• Pouch lithium battery prototyping and R&D
• Small-batch production of soft-pack batteries
• Electrolyte filling and vacuum sealing operations
• Glove box-based battery assembly
