The PolyDyne™ Corona Treating System

PolyDyne™ is the most versatile and efficient system in 3DT’s product line. It is specifically suited for the use in high-speed printing, assembly, extrusion and coating lines. Treatment from the interior surface of needle hubs to large bumpers and wide foam material is possible. PolyDyne allows the application of corona treatment to the exact part needed and increases adhesive properties regardless of shape. With PolyDyne it’s now possible to Corona treat virtually any three-dimensional polymer surface delicately, quickly and efficiently


State-of-the-art PolyDyne Corona treating systems include a full complement of accessories, and are designed for easy installation and maintenance. The PolyDyne Corona Treating System features:

A generator and one dry air transformer each enclosed within durable EMC-containing aluminum cabinets; the generator and transformer are connected via an EMC-shielded high frequency cable.

  • Dynamic generator with a liquid crystal display that shows watt-voltage applied and treating timer
  • Microprocessor controls
  • State-of-the-art, solid-state circuitry
  • An innovative frequency matching system that allows generator, transformer, and electrode systems to self-adjust and operator concurrently

PolyDyne Corona Treating Systems are designed for maximum flexibility; a series of transformers can be combined to produce optimal treatment for any application. For safe handling of the treatment voltage, a series of standard electrode components and modules are available. 3DT also offers system solutions including custom-made electrode systems, ozone eliminators, material handling systems, design, manufacturing, installation, and service.
