How Induction Cap Sealing Works

The food and medical industries require high-speed hermetic sealing between the cap and the container. Induction heating with Ambrell equipment provides the following benefits for cap sealing applications:

  • High reliability seals
  • Easy integration into production lines
  • High process speeds

Bonding Aluminum Foil to a Plastic Bottle (Cap Sealing)

It was confirmed that the aluminum heated sufficiently to create a bond between the foil and the bottle, meeting the client’s objective.

Sealing Aluminum Caps for the Beverage Industry

Induction delivers the same result time after time, making it ideal for this high-volume manufacturing process. The space-efficient 45 kW EKOHEAT fits nicely into the client's floor plan.

Sealing a Plastic Container with Induction Heating

An EASYHEAT and a workhead required a minimal footprint, saving the client floor space.

Sealing an aluminum disk onto a plastic cap

Induction heating enabled the aluminum to seal to the plastic cap quickly without the cap being damaged. The customer desired a quick rate which would make in-sourcing the process worthwhile, and induction heating exceeded the targeted production rate thanks to its fast heating.

Sealing aluminum foil cap to plastic bottle

Coil design can be incorporated to fit a wide range of production setups. Hands-free heating, involves no operator skill for manufacturing and directly heats only perimeter of foil.

Cap Sealing 3.5 Lotion Container

Power is applied directly to the foil; no energy is wasted heating the cap or the surrounding air or parts.

Cap Sealing; Shampoo Container

A three-turn two-position helical coil is used to heat the aluminum foil in a tunnel style assembly. Product (containers) passes easily under the induction coil.

About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide,carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
