The heat sealing machine operates at AC220V/50Hz with a maximum power consumption of 1000W and sealing temperatures up to 300°C. Proper electrical grounding and thermal insulation are required to prevent electrical shock and burn hazards.
- Electrical Supply Constraints: The machine requires AC220V/50Hz power supply with proper grounding to avoid electrical hazards.
- Temperature Control Limits: Upper die temperature must not exceed 300°C and lower die not exceed 300°C, with recommended values of 200°C and 100°C respectively.
- Pressure Adjustment Range: Sealing pressure must be adjusted within 0.5–0.7 MPa using the built-in pressure gauge to achieve consistent seal quality.
- Safety and Anti-Scald Protection: The machine incorporates safety and anti-scald features to protect operators from high-temperature burns during operation.
The heat sealing machine is used to seal aluminum-plastic film pouches for lithium-ion batteries by applying controlled heat and pressure. Operation requires setting precise temperature, pressure, and time parameters to ensure consistent seal quality without damaging the battery.
Required Equipment: Atomfair Heat Sealing Machine
- Set Upper Die Temperature
Set the upper die temperature to the recommended 200°C within the 0-300°C range. - Set Lower Die Temperature
Set the lower die temperature to the recommended 100°C within the 0-300°C range. - Adjust Sealing Pressure
Adjust the sealing pressure to between 0.5 and 0.7 MPa using the built-in pressure gauge. - Set Sealing Time
Set the sealing time to the standard 2-3 seconds or adjust within the 0-99 second range. - Position Battery Pouch
Position the pouch battery between the upper and lower dies for either top or side sealing. - Activate Sealing Cycle
Activate the sealing cycle to heat and press the film for the set duration. - Inspect Sealed Seam
Inspect the sealed seam for firmness, smoothness, and uniformity after cooling.
What is the optimal sealing temperature trade-off between upper and lower dies for pouch battery aluminum-plastic film to avoid thermal damage while ensuring seal integrity?
For pouch battery aluminum-plastic film sealing, the recommended temperature trade-off is 200°C on the upper die and 100°C on the lower die, as specified in the technical parameters. This differential ensures the film reaches a nearly molten state for strong bonding while the lower, cooler die prevents excessive heat transfer that could damage the battery cell. Upper and lower dies both have a maximum of 300°C, but the recommended temperatures balance melt quality and cell safety.
Can this heat sealing machine accommodate pouch cells with sealing lengths exceeding 300 mm or non-standard sealing widths?
No—the Atomfair HPF729 sealing head has a maximum sealing length of 300 mm for both side and top seals, and the standard sealing width is 5 mm (customizable upon request). Pouches requiring longer seals or thicknesses outside the 0.15–0.3 mm range are incompatible without modification, as the sealing head length and pressure parameters are fixed for those dimensions.
What infrastructure and safety provisions are required to operate the Atomfair HPF729 heat sealing machine in a lithium-ion battery lab?
The machine requires an AC220V/50Hz, 1000W power supply and a compressed air source delivering 0.5–0.7 MPa adjustable sealing pressure. Built-in thermocouple and thermostat provide precise temperature control, while the safety and anti-scald protection design minimizes burn risk during operation. No additional inert gas or ventilation is specified, but standard lab practices for battery handling should be followed.
The Atomfair Heat Sealing Machine (HPF729) offers precise temperature-controlled sealing for pouch lithium batteries with a copper head, supporting both top and side seals without mold changes. Its energy efficiency and compact design make it suitable for lab-scale battery assembly, though it is limited to specific film thicknesses (0.15–0.3 mm) and requires AC220V/50Hz power.
Positive
- No mold change for top and side sealing: This machine supports both top and side sealing without requiring mold changes, increasing production flexibility and reducing downtime.
- Over 50% energy saving: Compared to similar equipment, this machine consumes over 50% less energy, lowering operational costs per seal cycle.
Trade-offs
- Narrow sealing thickness range: The sealing thickness is limited to 0.15–0.3 mm, restricting compatibility to specific pouch films and requiring precise film specification.
- AC220V/50Hz power requirement: The machine requires an AC220V/50Hz power supply, which may necessitate a voltage converter or transformer in regions with different electrical standards.
