General Principles

Common Cap Liner Problems

In order to get a good hermetic seal, it's necessary for the foil innerseal (inside of the cap) to be in contact with the lip of the container and have consistent pressure around the circumference. This is accomplished by applying correct application torque to the cap. When the application torque is inconsistent, the result is inconsistent seals.

Operating Controls and Indicators

All units have some variation of the basic controls - status indicators, power output display, and 4-start/stop and up/down keys. The locations and additional functions vary by model.

Positioning your sealing head

Sealing head positioning is critical to successful sealing. The power of the electromagnetic field reduces by the square of the distance, meaning that if you double the distance between the seal and the head you only have 1/4 the sealing power.

Recommendations & Reminders for Integrating Sealers

Enercon offers a wide range of inspection, detection and rejection accessories for your cap sealer. These accessories were developed to help you achieve a perfect seal every time and to provide additional operational safeguards when integrating an induction sealer into a conveyor production line.

Setting your cap sealer power level

Follow these simple steps to find the optimal power level of your induction sealer for your application.

Starting your Enercon sealing system

These steps should be followed in the order listed to insure proper operation of your unit.

Tips for checking induction seals

How do I know if I have a proper seal? Due to the wide variety of sealing materials available, particular adhesion properties will have to be determined by the customer. Generally, proper sealing can usually be determined by the following questions.

Troubleshooting common induction sealing problems

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.

Understanding induction sealing

Induction sealing is a non-contact heating process that accomplishes the hermetic sealing of a container with a closure that includes a heat-sealable foil laminate. The typical induction innerseal begins as a multi-laminate liner inside a closure
