Sigma I Neo: 100% Air-Cooled Induction Cap Sealing Machine

Inline induction foil cap sealing for 20–120 mm closures at up to 32 feet per minute, on a single 230V single-phase supply.

The Sigma I Neo is the dependable, continuous-duty model in the Sigma Online Series. Built for round-the-clock production, it pairs a universal sealing head with in-built microprocessor control and built-in protection alarms, so packaging and quality teams get a consistent, tamper-evident seal across most bottle and container formats.

Dependable Induction Sealing for Every Production Line

The Sigma I Neo is known for trouble-free, reliable performance. Around the world and around the clock, these induction cap sealing machines run continuous-duty operations across a wide range of industrial applications, and the Sigma I Neo is designed to seal at up to 32 feet per minute.

Five decades of induction sealing R&D have been applied to almost every container shape and size, which is why factory managers and packaging engineers reach for it first: ease of operation, repeatable seals, and a build made for sustained output. If your product is filled in a container, whatever its shape and size, the Sigma I Neo will seal it at your line speed.

How the Sigma I Neo Seals Your Containers

The Sigma I Neo seals without contact. A capped container passes under the sealing head (Sealing coil), and an electromagnetic field bonds the foil liner to the container to create a hermetic, tamper-evident seal.

1

Capped Container Enters

Filled, capped containers move along the conveyor toward the sealing head (Sealing coil) at your set line speed.

2

Passes Under the Sealing Head (Sealing Coil)

Each container passes beneath the universal sealing head, with no contact between machine and cap.

3

Foil Liner Heats

The electromagnetic field heats the foil liner inside the cap, melting its bonding layer.

4

Hermetic Seal Forms

The liner bonds to the container rim, forming a leak-proof, tamper-evident seal as the container exits.

Why Choose the Sigma I Neo

The features that make the Sigma I Neo a dependable, low-effort sealer for demanding production lines.

Easy to Move

The machine is mounted on a wheel-based unit, so it can be relocated quickly from one line to another with minimal disruption.

Saves Power

Latest solid-state semiconductor technology delivers more than 90% power conversion efficiency, so the machine draws less power for the same work.

Safety & Protection Alarms

Built-in protection circuitry guards against over-current, over-voltage and over-temperature, included at no extra cost.

In-Built Microprocessor Control

Microprocessor control keeps sealing consistent and repeatable across long production runs.

Universal Sealing Head

A universal sealing head covers a wide range of closures, available as a flat, deep tunnel, peep tunnel or customized head.

User-Friendly Operation

No tuning and no tools. Plug into a 230V single-phase mains supply and seal, using simple digital soft-touch membranes.
