The SealerOn™ 3000: Versatility at Its Finest

The SealerOn 3000: Versatility at Its Finest

Two important aspects of induction sealing that greatly affect efficiency of production are 1) the speed of the conveyor bringing the products towards the induction sealing head, and 2) the capacity of the induction sealer to work with products with varying cap sizes.

The speed by which a conveyor passes the product under the sealing head is directly related to the sealing power, therefore, acquiring a variable speed product conveyor will allow you to get the most out of your induction machine at any power setting.

With other machines, another issue to be addressed is the lack of versatility when it comes to sealing caps with varying sizes. The SealerOn™ 3000 can be fitted with our Universal Flat Cap Induction Sealing Head. This enables you to run a flat cap ranging in size from 20 mm up to 120 mm, all without needing to constantly adjust the sealing head angles—something other machine manufacturers expect you to do.

With the SealerOn™ 3000, you are assured of efficiency and versatility with your production lines.

The SealerOn™ Mini: Small but Powerful

The SealerOn Mini

The SealerOn™ Mini is a small powerhouse and workhorse for induction sealing. The next step up from a Semi-Automated Bench-top Induction Machine, this incredible device has its own conveyor, streamlining your production processes.

How does The SealerOn™ Mini work?

The SealerOn™ Mini is designed to run inline with the LabelOn™ Mini label applicator, allowing you to have your own mini production line while maintaining an impressive daily production capacity. The machine is also compatible with Epson Colorworks Label Printers, allowing you to print your own labels while the machine does the sealing for you—all on a single table!

Furthermore, the SealerOn™ Mini was devised with the consumer in mind. The machine prevents the sealing head from starting when the conveyor is off, ensuring no issues arise during production. An optional back-up sensor is also available to prevent the piling up of products when there is no available path for them to exit the sealing head area. If this sensor is activated continuously for too long, the sealing head will automatically turn off.

Capless Induction Sealing Glass Bottles with Metal Lids

Capless Induction Sealing with Metal Lids

This is SealerOn’s 5-head capless induction sealing machine. With this, dry products packed into glass can be induction sealed—even if the package has a metal lid. The machine fills the glass jars, adds a desiccant and then the Capless Induction Sealing Process takes place. Finally, an attractive metal cap is placed over the sealed top of the glass jar.

Products are finished in a high-end glass package with tamper evidence and a moisture and oxygen barrier with close to zero transmission rates.

How does our 5-Head Capless Induction Sealing Machine do it?

Rolled induction sealing material is cut and applied to the top sealing surface of the vial. Our unit has 5 filling sealing heads allowing for higher processing speeds. The sealing cycle then lasts 0.2 to 0.4 seconds introducing only minimal heat energy to produce the seal.

Key Benefits to Capless Induction Sealing

100% visual inspection of the seal is possible.
More pressure can be applied at the time of sealing resulting in a better and more even contact during the induction sealing cycle.
For single-use containers, the process can eliminate the need for multi-layer cap lining or even eliminate the need for a cap altogether.
For containers with metal/metalized plastic caps, tamper evidence is still achievable along with a moisture and oxygen barrier with close to zero transmission rates.

Induction Sealing Bottles with Specialty Caps

Induction Sealing

A Tunnel Induction Sealing Head lets you seal caps where the foil sits a distance greater than say 4 mm from the top surface of the cap; This is often the case with twist top spouts, flip top lids, sports drink caps, sipper caps or shaker caps.

Induction sealing is a process where a coil in the shape of an elongated loop is used to generate a fast oscillating high magnetic field. This magnetic field can change poles as many as 100,000 times every second.

The magnetic field can travel through air and plastic. When the magnetic field meets a metal surface, the magnetic field “induces” a high oscillating current in that metal surface in a plane that is parallel to the coils that generated the magnetic field.

A magnetic field generated from a “point” dissipates with the cube of its distance from that point.

In general, the magnetic field of an induction sealing machine needs to be within 5mm or ¼ inch from the sealing foil to obtain meaningful production speeds.

There are a large range of caps that do not fit the standard flat top profile and present a problem to bring the magnetic field of the heat sealing equipment to within 5mm or ¼ inch from the sealing foil.

These specialty caps need an adaption from a standard flat coil sealing head to a tunnel sealing head. The Coils are shaped to pass around the tunnel. The tunnel allows the protruding feature of the specialty caps to pass through the machine without lifting the plane of the magnetic field further away from the sealing foil within the bottle cap.

On the SealerOn website there is a youtube icon that will link you to videos showing SealerOn™ heat sealing or more accurately induction heat sealing using a tunnel sealing head.

The SealerOn™500 fitted with a sealing tunnel is capable of sealing at sealing speed up to 10 Meters per Minutes or 30 Feet per Minute depending on the cap and foil combination.

For faster induction sealing there is the MeRo adjustable tunnel sealing machines. These machines have the added and unique feature of having an adjustable width sealing head. Having an adjustable width enables higher concentrating and focussing of the induction field allowing for higher speed sealing. A MeRo 2Kw unit is capable of sealing at sealing speed up to 30 Meters per Minutes or 90 Feet per Minute depending on the cap and foil combination.

Efficient cap sealing means that less time is needed under the sealing head and hence higher production speed is possible.

A Flat profile sealing head will allow for a greater range of cap sizes and even allows for that Sealing head to be placed at an angle across the product’s path to achieve sealing of cap diameters that are even wider than the coil winding pattern within the sealing head. It is quite possible to have a Flat profile sealing head that can seal caps from 30mm to 110mm wide. The trade-off for the versatility of this profile sealing head on a heat sealing head is lower speed throughput and an inability to seal specialty caps.

SealerOn™ Large Caps

Large Caps

The SealerOn™ Induction Sealing Machine range is a versatile entry level range aimed primarily at Flat Cap induction sealing applications.

The SealerOn™ 3000 is typically rated for Flat Caps of Diameter 20 mm to 120 mm traveling on a conveyor at speeds up to 20 Meters (60 Ft) per minute.

The Actual Speed needs to be determined with the Cap, Lining Material and Bottle combination to hand. The Standard frame Allows the Sealing Head to be adjusted from 710 mm to 1200 mm above the floor Level. This height range can be “offset” up or down upon request. Technicians are not expected to repair any components.

Ideally a spare Generator is on hand or can be provided while the Generator is sent to our manufacturers service center for repair.

MeRo Flat Caps

Flat Caps

With Induction sealing it is important to identify if your range of plastic caps is considered “Flat Caps” or specialty caps.

A “Flat Cap”, generally speaking, refers to a cap where the plane of the induction liner is within 4.0 mm of the plane of the Cap’s top surface.

See the picture below:

With only Flat Caps, a Flat Sealing Head can be provided.
With A Flat Sealing Head it is possible to cater for a wide range of cap sizes.

The energy transfer for a Flat Sealing Head is not as efficient as a Tunnel sealing head but the versatility often makes up for the reduced speed throughput compromise of a Flat Sealing Head
