As packaging equipment evolves, many suppliers adopt similar model names. However, good equipment should be evaluated based on multiple factors, such as product quality, equipment structure and configuration, actual packaging results, supplier service and support, parts availability, and equipment lifespan.

1) Check whether the switch for the heating element is turned on.

2) See if the indicator light on the switch illuminates; if it does not, the switch may be faulty, or a wire might have come loose.

Check whether the actual temperature of the heating block matches the temperature set on the controller; also, check for any temperature difference between the top and bottom of the heating block—if one side is cooler, the corresponding heating element is faulty.

1) Reduce the heat-sealing speed and check if the sealing quality improves.

2) Verify the temperature controller: Compare the set temperature with the actual displayed temperature.

If the temperatures match: The heating system is functioning correctly. If no seal forms at all, increase the temperature by ≥10°C; if the seal is weak, increase it by 5°C and test again.

If the temperatures do not match: If the temperature fails to reach 150°C after more than 10 minutes of heating, the heating system is malfunctioning.

3) Diagnose heating issues: If the "run" indicator light is off, the temperature controller is faulty and needs replacement. If the "run" light is on but no heating occurs, there is an issue with the heating element or the wiring—please contact after-sales support.

4) If a seal forms but is not secure: Increase the pressure on the embossing roller.
