How to Find the Right Operating Window for Induction Sealing

Achieving a consistent, reliable seal starts with dialing in the correct operating window for your application. In this video, Enercon’s Jessica Toellner walks you through a step-by-step method for identifying the optimal power range for your induction sealer—so you can achieve perfect seals, every time.

Step 1: Verify Sealing Head Air Gap and Container Alignment
Step 2: Verify Your Conveyor Speed (Pro Tip: A handheld tachometer is an invaluable tool for this step.)
Step 3: Verify you cap torque
Step 4: Follow the steps below to determine the power levels of your operating window

To determine the top power level for your sealing window:

• Once you achieve a perfect seal increase power level by 5% until there are signs of the liner burning or wrinkling
• Then reduce the power level by 1% until you seal a container without signs of burning or wrinkling
• This is the top power level for your operating window

To determine the low power level for your sealing window:

• From the power level you first achieved a perfect seal, reduce the power by 5%
• When you find the level that the seal is imperfect, increase the sealing power by 1% until you achieve a perfect seal
• This is the low power level for your operating window

Select an operational power level within in the operating window that best suits your operation.
