Manual vs. Automatic Induction Sealer: Which One to Choose?
If you are evaluating options to optimize the sealing of your containers, you are probably wondering which is the best option between a manual sealer and an automatic induction sealer. Both fulfill the same function: generating a hermetic seal through the heating of aluminum liners. But the differences in speed, capacity and automation can be decisive for your operation.
At SellaEmpaq, we help you understand their advantages and limitations so you can make the right decision.
What is a manual induction sealer?
A manual induction sealer is a portable and compact piece of equipment that applies sealing one by one, activating the electromagnetic field with a button. It is designed for small or medium-sized operations, where an automatic line is not required.
Advantages:
-
Low initial cost
-
Ideal for startups or limited production.
-
Portable, easy to use, and requires no complex installation.
-
Compatible with liners from 20 to 120 mm (SellaEmpaq model)
Limitations:
-
Requires constant manual intervention.
-
Not suitable for high production volumes
-
Lower speed (5–8 containers per minute)
What is an automatic induction sealer?
The automatic sealer integrates directly into your production line. It features an induction head that seals containers as they pass along a conveyor belt, without operator intervention.
Advantages:
-
Continuous and precise sealing
-
High speed (up to 40 containers per minute)
-
Reduction of human errors
-
Ideal for companies with high demand and automated lines
Limitations:
-
Initial investment
-
Requires space and technical setup.
-
Reduced portability
