Is the induction seal ability affected if more bottles are under the induction sealing head at one time?
Enercon induction sealers regulate a fixed output current value (at a given output percentage). This design ensures the eddy currents induced in each foil are consistent whether one container or several containers are under the sealing head at a given time.

With a ”flat head” sealer, do you recommend the head be angled for closures that range from 28mm to 38mm?
Enercon’s all in one flat sealing head shouldn’t need to be angled for the diameter closures mentioned. This can be verified by checking the quality of the sides of the seal near either extreme of the sealing window.

In setting up min and max energy levels, do you go by a statistical level of good seals (at min level), and statistical level of overheated ones at the max? Or, just when you see ONE good and ONE overheated?
We encourage customers to incorporate specific quality standards, including statistical sampling to check for errors. A statistical method would be ideal to determine the best setting, but you would need at least 30 samples at each level to begin to be statistically significant. Recognizing that the Enercon induction sealer regulates a fixed output current, ensuring consistent power delivered to each foil liner at a given output percentage, checking one bottle at a time is often used as long as all other variables are verified and consistent.

Have you used 6 sigma tools to help a customer determine a optimal sealer setting?
This is an excellent idea, and in fact something Enercon is evaluating. As of today, specific quality standards are determined by the customer. Though the induction sealer is an integral part of the sealing process, there are many other variables outside of the direct control of the induction sealer.

What advice or guidelines can you give for intermittent FPM or CPM, can this drastically affect ouput of sealing heads? The more foils under the head, the bigger the power draw – and the less foils under the head = surplus?
For lines that will have speed variations beyond your operating window Enercon offers an option called Variable Sealing Control which automatically adjusts output power based on changes in line speed to ensure consistent sealing. Enercon induction sealers regulate a fixed output current value (at a given output percentage). This design ensures the eddy currents induced in each foil are consistent whether one container or several containers are under the sealing head at a given time (intermittent CPM). If the conveyor speed (FPM) varies, the amount of time the foil liner is under the sealing head is also varying. You need to ensure that the speed variation is within the operating window that you have set-up. Otherwise you may have varying sealing success without the Variable Sealing Control Option.

What is the Optimal air gap? 70mm and 53mm cap
The optimal air gap is dependent on the manufacturer’s specification for a given sealing head coil. A typical air gap is between 1/8” (3 mm) and 3/8” (10mm) based on your manufacturer’s specifications. Variations in your bottle height may also impact your settings.
