Key Features & Advantages
  • High-Efficiency Thermal Transfer: Premium solid copper sealing head provides rapid heat conductivity, lowering energy consumption and shortening cycle limits.
  • Adjustable Dynamic Compression: Pressure regulators allow users to completely fine-tune and balance upper and lower head forces for optimal film flow characteristics.
  • Pristine Parallel Motion: Cylinder-driven mechanics paired with precision linear guide sleeves safeguard parallelism metrics below ≤0.02 mm boundaries.
  • Separated Hardware Layout: Detached main vacuum unit and external control box design allows the sealer to reside natively inside an inert glovebox workspace or inline over custom conveyor networks.
  • Integrated Inspection Geometry: Large transparent observation window enables real-time visual tracking of vacuum pull-down and sealing jaw interactions without breaching containment fields.

APPLICATION SCOPE: Automation of pouch cell vacuum heat-sealing, aluminum-plastic film hot-pressing protocols, electrolyte wetting workflows, and experimental battery cell prototyping lines.
PACKAGING: Shock-isolated, heavy-duty industrial shipping container protecting separate structural segments, umbilical controls, and pneumatic valves from external transport variables.
IMPORTANT NOTICE: This advanced processing machinery setup must be deployed and maintained in accordance with established laboratory or plant mechanical engineering protocols. Always connect an independent, stable air supply meeting the 5–7 Kg/cm² pressure profile before starting programmable cylinder strokes to prevent alignment skewing. If you are interested, have specific customization parameters, or require alternative cell geometry adaptation brackets, please feel free to request assistance from our engineering support coordinators.

The Atomfair-SEA-169 vacuum pre-sealing machine requires a controlled environment for safe operation due to flammable electrolyte vapors from pouch batteries. The machine demands a regulated compressed air supply and grounded electrical connection to prevent mechanical and electrical hazards.

  • Electrolyte vapor containment: Operate the machine inside a glovebox or with adequate ventilation to avoid exposure to flammable electrolyte vapors.
  • Electrical grounding requirement: Connect the machine to a grounded 220V AC power source to prevent electrical shock and equipment damage.
  • High temperature burn risk: Allow the sealing head to cool before maintenance and use insulated tools when handling hot components.
  • Compressed air pressure limits: Maintain the air supply between 5 and 7 kg/cm² to ensure proper cylinder operation and avoid overpressure damage.
  • Vacuum chamber integrity: Regularly inspect the chamber seals and window for leaks or cracks to maintain vacuum performance and safety.

This procedure guides the user through vacuum heat-sealing a pouch lithium battery after electrolyte injection. Follow all safety instructions to prevent injury and ensure consistent seal quality.

Required Equipment: Atomfair-SEA-169 Vacuum Pre-Sealing Machine

  1. Set sealing temperature
    Set the sealing temperature on the controller between room temperature and 300°C based on the pouch material.
  2. Adjust sealing time
    Adjust the heat-seal time from 0 to 99 seconds using the timer dial.
  3. Set vacuum level
    Set the vacuum level to the required value up to -95 KPa using the vacuum regulator.
  4. Load battery pouch
    Place the electrolyte-injected pouch battery into the sealing chamber with the seal area aligned under the copper head.
  5. Close chamber cover
    Close the chamber cover and engage the cylinder-driven locking mechanism to create a seal.
  6. Start vacuum and sealing cycle
    Initiate the vacuum and sealing cycle by pressing the start button on the control panel.
  7. Retrieve sealed pouch
    Release the vacuum and open the cover after the cycle completes to remove the sealed battery.

What is the trade-off between vacuum level and seal integrity for pouch cells with different electrolyte volumes?

The vacuum level is adjustable up to -95 kPa, and the heat-seal time ranges from 0 to 99 seconds with temperature up to 300°C (±2°C). Higher vacuum levels reduce gas pressure but may cause electrolyte foaming; however, the adjustable parameters allow optimization for specific electrolyte volumes. The parallel gap ≤0.02mm ensures uniform pressure distribution regardless of vacuum level.

Can the Atomfair-SEA-169 seal pouches with a sealing tab width narrower than 5 mm, or is it limited by the standard 5 mm sealing width?

The sealing head has a fixed sealing width of 5 mm and a length of 300 mm. Pouches requiring a narrower seal width cannot be accommodated. However, the machine is compatible with various battery sizes via easy adjustment of the head pressure and positioning, but the seal width is non-adjustable.

What are the compressed air quality and pressure requirements for reliable operation of this vacuum pre-sealing machine?

The machine requires a regulated air supply of 5–7 kg/cm² (approximately 71–100 psi). The air must be dry and clean to avoid contamination of the cylinder and linear guide sleeves. The separated control box design allows the main unit to be placed inside a glovebox, but the air supply must still meet these pressure and quality specifications.

This vacuum pre-sealing machine offers precise temperature control (±2°C accuracy) and high parallelism (≤0.02 mm gap) for reliable pouch cell sealing, but requires a compressed air supply (5–7 Kg/cm²) and occupies significant lab space due to its 60 kg weight and separate control unit.

Positive

  • Copper sealing head for efficient heat transfer: The copper sealing head provides excellent thermal conductivity, reducing energy consumption and ensuring consistent heat distribution across the 300 mm sealing length.
  • Precise thermal and vacuum control: Adjustable temperature from room temperature to 300°C with ±2°C accuracy and vacuum up to -95 KPa enable repeatable sealing conditions suitable for various pouch cell chemistries.

Trade-offs

  • Requires compressed air supply: The cylinder-driven mechanisms demand a compressed air source at 5–7 Kg/cm², adding infrastructure requirements to the lab or production line setup.
  • Large footprint and weight: The combined machine and control box occupy approximately 570×485×435 mm and 520×325×225 mm, weighing about 60 kg, necessitating sturdy benching and adequate floor space.
