How It Works
The DGFY-200 creates a tamper-evident seal through non-contact electromagnetic heating:
-
Bottle Preparation:
Ensure the bottle is filled and the induction foil liner is inserted into the cap. -
Cap Closure:
Tighten the cap securely on the bottle. -
Sealing Process:
Place the handheld induction coil above the bottle cap and trigger the sealing cycle. -
Induction Heating:
The coil emits a high-frequency magnetic field, which heats the aluminum foil. -
Seal Formation:
The heat melts the polymer layer under the foil, bonding it to the rim of the bottle. -
Seal Completion:
After cooling, the foil remains tightly attached, preventing tampering or leaks.

User Instructions
-
Connect the machine to a stable power source.
-
Adjust the timer using the digital interface.
-
Hold the sealing head over the cap for the desired time.
-
Wait for the beep or indicator to confirm sealing.
-
Let the bottle cool for 3–5 seconds.
-
Test the seal by trying to lift the foil – it should not peel without breaking.
Troubleshooting Guide
| Issue | Cause | Solution |
|---|---|---|
| Foil not sealed | Low time/power | Increase power or time |
| Foil burnt or warped | Excess heat | Reduce sealing time |
| Machine not turning on | Power supply issue | Check fuse, plug, voltage |
| No beep or cycle fail | Timer misconfiguration | Reset digital timer |
| Weak seal | Incorrect foil or bottle mismatch | Use correct liner & check alignment |
