Cap Sealing Operating Window

Setting a cap sealing operating window for each of your applications is the best way to establish a quality control process for your production team. If you have any questions about the information below please contact us.

Follow these steps:

1. Set the sealing head to cap air gap as directed by your induction sealer supplier
2. Set conveyor speed for product being tested. Set the sealing head to cap air gap as directed by your induction ssealer supplier
3. Examine the container and caps for defects and compatibility. Set the sealing head to cap air gap as directed by your induction sealer supplier
4. Verify cap torque. Set the sealing head to cap air gap as directed by your induction sealer supplier
5. Set the output % at minimum and run a single container. Check seal quality.
   1. If no seal was achieved, increase the output % in increments of 10% until a partial seal is achieved and go to the next step
   2. If a partial seal was achieved, increase the output % in increments of 1-2% until a complete seal is achieved. This is the minimum set point of the operating window.
6. Once the minimum set point is established, increase the output % by 1-2% until the liner or cap show signs of overheating.
   1. Decrease output by 1% until the overheating is eliminated. This is the maximum set point of the operating window.
7. Test the application in the range of output from minimum to maximum to determine at what output % the best seal is achieved. This will be the production output level.
8. Record the minimum/maximum output % of the window, production output %, line speed, cap, liner material and container information for future reference.
9. Repeat all steps for each application that is run on the equipment.
