Tips to help solve common sealing problems
Enercon induction cap sealers are designed for reliable and trouble-free operation. Once you've setup your system and achieve that perfect seal, every container will seal consistently given no variable in the process changes.
What if you are not getting a desirable seal? Induction sealing is affected by these variables: air gap, line speed, power output and cap application torque. The table below details common sealing problems and tips to solve them. Our General Principles links on the technical support home page contains links to other documents which address the variables of induction sealing.
How do you know if you are achieving a proper seal? Read our Tips for Checking Induction Seals .

| Troubleshooting Guide |
| Symptom |
- Insufficient power from sealer: conveyor set too fast, power set too low.
- Improper coil height.
- Insufficient torque on cap.
- Induction liner incompatible with bottle material.
- Bottle neck finish has been flame or chemically treated.
- Imperfections in container finish, land area.
- Metal guide rails located too close to sealing head. Guide rails under sealing head should not be metal because they can distort the electromagnetic field.
- Excessive power from sealer.
- Liner larger than neck, creates overhang.
- Insufficient power from sealer:conveyor set too fast, power set too low (insufficient wax melt).
- Improper coil height, coil too high.
- Excessive cap application torque.
- Foam liner polymer welds to polymer in induction liner.
- Excessive power from sealer: conveyor set too slow, power set to high.
- Bottle backup under sealing head.
- Insufficient cap application torque
- Insufficient cap application torque: closure not securely applied.
- Excessive application torque: threads of closure stripped.
- Excessive power from sealer: conveyor set too slow, power set too high.
- Retorquing too soon after induction sealing.
- If the power output is steady and one container seals, all should seal. The fault is not with the induction sealer. Check to make sure the caps are all being torqued evenly and are not cocked. Also check the bottle seating areas for uneven surfaces, burrs, etc.
