Plasma-Jet® | Corotec


For improved bonding of inks, adhesives, and coatings, our Plasma-Jet® treats plastic and metal products with greater application flexibility, surface coverage, and speed.

We have advanced our surface treating technology with new generation Plasma-Jet® corona treating systems for 3D products. Now you can treat multiple surfaces and difficult configurations with superior one-pass coverage, consistency, and convenience.

Capable of handling high line speeds and complex part geometries, Plasma-Jet systems readily solve surface adhesion problems for a wide variety of products and applications:

  • Caps and closures
  • Painting and decorating
  • Cups and containers
  • Consumer products
  • Extruded pipe, tubing, profiles
  • Medical and health care products
  • Electrical/electronic components
  • Direct printing
  • Hot stamping
  • Pad printing
  • Adhesive coating
  • Adhesive bonding
  • Wire and cable
  • Laminating

The Plasma-Jet corona discharge generates very little heat, which allows surface treating of sensitive materials, such as light films, without distortion.

Plasma-Jet corona treatment eliminates the inefficiencies, safety hazards, and product damage potential of open flame treatment, chemical surface preparation, and sanding techniques, while offering improved bonding results as well. We’ll prove it…on your product…in our lab or in your plant. Call us today.

Application Flexibility

Simple and compact, Plasma-Jet systems can be sized and configured to suit your production environment. They are easily matched to your line speed, required treatment width, product material, and configuration. The Plasma-Jet power unit is portable and can be moved wherever needed, or permanently mounted in a convenient location. The discharge heads (one to four, depending on model selected) can be extended up to 10 feet or more away from the power unit. Optional universal mounting brackets are available to hold the discharge heads at the right angle and position on your production line, and they are especially handy when your treatment applications change frequently. A proximity sensor can also be added to cycle the corona discharge on and off as parts approach and leave the treatment station.

NEW Plasma-Jet® Alarm Monitors Multiple Functions

All Plasma-Jet® units can incorporate an optional Alarm System which is designed to continuously monitor the operating parameters of each discharge head and provide a separate output for each head if any discharge head falls outside of normal operation.

The Plasma-Jet® alarm system monitors the following functions:

  • Blower power
  • Blower speed
  • Head Select
  • Output power

The Plasma-Jet® alarm system utilizes a separate 4-quadrant, real-time, precision analog multiplier to calculate output power for each discharge head. Output levels are then buffered, amplified, and finally sampled by an embedded microcontroller which uses proprietary software to monitor discharge head function and output level at rates of at least 1,000 samples per discharge head per second, or more, depending on the number of heads being sampled.

The alarm system is designed to function automatically in both continuous and cycling modes of operation, and is available for both new equipment installation and field retro-fits.
