Planning induction sealing after powder filling.
Good sealing depends on more than the induction unit; the filled pack must arrive clean, stable and correctly closed.
Start with the product, pack and required output.
For jars and tubs, induction sealing may be used after filling and capping. Powder on the rim, trapped dust or poor cap application can affect sealing quality, so the filling and closing stages need to be aligned.
The line should allow the product to settle and the cap to be applied consistently before the container passes through the sealing head. Container diameter, cap type and line speed all influence the final specification.
Details that help narrow the specification
- Jar or tub material and closure type
- Foil liner and cap specification
- Dust control before closing
- Line speed and conveyor stability
- Inspection or rejection after sealing
Points to confirm before choosing equipment.
These checks help compare semi-automatic, automatic and line-integrated options against the way the product will actually be packed.
Check the powder level after settling and before closing so product is kept clear of the rim, liner and cap application area.
Confirm consistent cap application with the chosen container and liner, using the agreed torque-check method before assessing the induction seal.
Provide the container diameter, cap and liner specification and line speed so the sealing-head arrangement can be reviewed against the actual pack.
Agree how seal quality will be checked and how failed packs will be identified and removed after the sealing stage.
Common questions from machinery buyers.
Can induction sealing follow auger filling?
Yes. It is common on rigid powder packs when the container and cap are suitable.
Why does dust matter for sealing?
Dust can sit on the sealing surface and interfere with closure quality.
Should I supply cap and liner samples?
Yes. Samples help confirm capping and sealing requirements.
