Plasma and Corona

 

Two very different treatment types, usually with very similar results - in most cases, the main considerations are ‘how and where will the equipment be used?’ and ‘what does the part look like?’

Atmospheric Plasma

PlasmaTEC-X (PLX) technology, a nozzle based system is perfectly suited for mounting above an extrusion line, moving component, or using with a robot.

There are various versions, including single-head, multi-head, wide/ large area and OEM.

This is usually the easiest system to integrate, even in to existing automation or production lines.

Vacuum Plasma

For a more comprehensive treatment, treating an entire surface without the need for a complex robot program, Vacuum Plasma is the most likely technology to use.

A batch/ inline batch process which usually takes 2-5 minutes to run, a chamber is loaded with the parts and the door closed. The chamber will run at around 1/1000th of atmospheric pressure and create a plasma through the whole chamber rather than a focused jet like atmospheric plasma.

This chamber of plasma will get in and around all parts of the component, even if there are complex features and geometry to the part.

Corona - Spot Treater

Almost a hybrid between atmospheric plasma and outright corona, the SpotTEC system is a low cost treatment system which is a good starting point for a lot of projects.

It has a lot of similar features to the Atmospheric Plasma systems, but usually runs a little slower and wider than those systems.

3D Corona

Corona systems are usually built for purpose, they are efficient and targeted to specific areas for high speed production.

Corona systems require some thought for their integration but once installed they are very low maintenance and can offer feedback to ensure 100% of the parts are treated and monitored.

Web and label corona

For continuous treatment of web materials, corona treatment is best suited as it can be made multiple meters wide and run at excessive speeds well into the 100s meters per minute.

Automatic treatment output control for inline system with a variety of options for different materials and different widths available to suit your production needs.

Leaktec

High voltage leak detection works by accurately monitoring the resistance in a circuit - a good part is placed in the circuit and the resistance is usually high.

Even with a invisible to the eye sized hole, high voltage will find the quickest path through and the resistance will be minimal and causing a signal to be produced.

An individual part, or series of parts can then be removed.

Most importantly, this gives 100%, inline inspection for pin holing without the need for gases or manual intervention.

ozonetec

Usually lesser known, the OzoneTEC system produces ozone which when in contact with polymer surfaces creates a good surface for adhesion.

This method is usually slower, but has the major advantage that ozone will flow in to enclosed spaces with complex geometries to treat areas that you could never touch with plasmas and coronas.

Key ozone projects have been to treat the inside of rotomoulded parts prior to foam application
