Sealing Heads and Induction Cap Sealers

The most popular induction cap sealing machine in the industry



There are three main components to an induction cap sealer; the power supply, the operator interface and the sealing head. When you purchase an Enercon Super Seal™ cap sealer our team expertly matches the power supply, interface and sealing head to meet your specific application requirements.

Packagers sometimes overlook the importance of the sealing head design. While the power supply plays a significant role, the efficiency of your sealing operation depends on the design of the sealing head. The secret to creating fast, efficient, and consistent seals is the energy transfer from the power supply to the sealing head and into the foil liner. If you don't have the correct design, increasing the power only wastes energy.

There are a number of key application variables taken into consideration when Enercon recommends an induction sealer configuration. These variables include line speed, cap diameter, cap type, and liner type. When any of these variables change you should consult with Enercon to see how your current sealer is equipped to handle the new set up. In some cases no changes to your set up are required. In other cases an adjustment to the power level or line speed will ensure successful sealing. It is also possible that your operation would benefit from a second sealing head designed to better accommodate your additional application.

Sealing Head Types

Enercon engineers sealing heads in three general classifications: Flat, Tunnel, and All-in-One.

All-in-One Sealing Head

Available with the Super Seal™ and Super Seal™ Touch these flat sealing heads can be pivoted to accommodate various applications. They are capable of sealing containers with cap diameters ranging from 20mm to 120mm. They are ideal for packagers who seal a variety of packages and offer the highest degree of sealing versatility.

Flat Sealing Head

As a general rule this sealing head is used for containers with cap diameters greater than 53mm where the foil is near the top of the closure.

Tunnel Sealing Head
Tunnel sealing heads are generally used in two situations, when the foil liner diameter is less than 53mm and for closures where there is a larger gap between the liner and the top of the closer. Examples of this include child resistant caps and many dispensing caps.
