Heat Sealing Machine HSM729 300°C 0.5–0.7MPa ATOMFAIR®

The HSM729 requires strict adherence to thermal and pressure limits to ensure safe and consistent sealing of aluminum-plastic film. Exceeding recommended temperatures or applying pressure without proper setup may cause equipment damage or operator injury.

• Thermal Limits: Operate the upper mold at a maximum of 300°C (recommended 200°C) and the lower mold at a maximum of 300°C (recommended 100°C) to prevent material degradation and ensure sealing integrity.
• Pressure Monitoring: Maintain sealing pressure within the adjustable range of 0.5–0.7 MPa, using the built-in pressure gauge for real-time monitoring to achieve consistent, repeatable seals.
• Safety and Anti-Scald Design: Exercise caution around heated sealing heads despite the anti-scald design, as the surfaces can reach high temperatures and cause burns.

This procedure outlines the safe and effective operation of the HSM729 for sealing aluminum-plastic film in pouch battery fabrication. Follow these steps to achieve consistent, high-quality seals while minimizing risk.

Required Equipment: HSM729 Heat Sealing Machine, Aluminum-plastic film pouch

1. Preheat
   Set the upper mold to 200°C and the lower mold to 100°C, then allow the machine to preheat until the temperature controller indicates stable temperatures.
2. Set Sealing Parameters
   Adjust the sealing time to 2–3 seconds and the pressure to 0.5–0.7 MPa using the machine's controls, verifying the settings on the pressure gauge.
3. Position the Pouch
   Place the aluminum-plastic film pouch on the lower mold, aligning the sealing area with the heated upper mold.
4. Initiate Sealing
   Activate the sealing cycle by pressing the foot switch or start button, ensuring hands are clear of the heated area.
5. Inspect the Seal
   After the cycle completes, lift the upper mold and visually inspect the seal for uniformity and integrity, ensuring no gaps or defects are present.

The Atomfair HSM729 heat sealing machine is engineered for flexible-packaged lithium-ion battery sealing, offering precise thermocouple-based temperature control up to 300°C and adjustable pressure of 0.5–0.7 MPa. Its dual-mode top and side sealing capability without mold changes, combined with a compact footprint and energy-saving design, makes it suitable for research and pilot production environments.

Positive

• Precise temperature control: Thermocouple feedback and PID controller maintain constant sealing head temperature, ensuring consistent sealing quality across batches.
• Dual-mode sealing without mold change: Supports both top and side sealing up to 200 mm without mold replacement, improving operational efficiency and reducing consumable costs.

Trade-offs

• High-temperature operation risk: Maximum 300°C capability requires caution; recommended operating temperatures are 200°C (upper) and 100°C (lower) to avoid material degradation or safety hazards.
• Pressure and time sensitivity: Sealing quality depends on precise pressure (0.5–0.7 MPa) and time (2–3 s standard) settings; deviations may affect bond integrity, requiring operator expertise.
