MultiDyne’s technology creates powerful bonding for printing, coating and adhesive applications and is especially suited for polymer parts. Simple and complex 3-dimensional shapes are treatable with the flexibility of the MultiDyne system.

MultiDyne can be incorporated into existing or new production lines or as a stand-alone workstation. Each system is furnished as a complete set of standard components, including a generator with high-voltage transformer(s), air supply system, treating head(s), control panel and fault monitoring system. MultiDyne is available with single or multiple treating heads, depending on your application.

MultiDyne Advantages:

  • MultiDyne is available with 1 to 4 treating heads. Custom systems with more treating heads are available.
  • Corona treatment is delivered to unlimited lengths of material in widths up to 2.5 inches (65mm) per head.
  • The generator supplies power to high-voltage transformer(s) which then directly supply the treating head(s), resulting in low-frequency corona discharge.
  • Capable of treating surfaces adjacent to metal inserts or areas held in a metal fixture

Next Generation FlexiDyne Pro

FlexiDyne has been an important system in 3DT’s product line for years. But, changing technology has led to several improvements including, a redesigned generator capable of producing a larger corona field, higher surface treatment levels, faster production and the ability to treat larger parts.

FlexiDyne Pro

Flexibility in Corona Treatment

FlexiDyne Pro™ is a self-contained corona-treating system designed to treat 3-dimensional plastic parts. The FlexiDyne Pro system substantially raises surface energy and thereby improves bonding on polymer parts. It is ideal for the treatment of labware, eye lenses, headlight housings, container lids and numerous other applications. Any non-metallic item up to 12” wide by 1.5” high (350mm x 35mm) can receive uniform corona treatment of all exposed areas without set-up changes. FlexiDyne Pro can be operated as a stand-alone workstation or integrated into a production line.

FlexiDyne Pro Advantages:

  •  Improves adhesion for printing, painting, coating, and adhesive applications
  •  Alters surface chemistry for improved adhesion of cell and tissue culture growth
  •  Recipe-based menu operation provides consistent results
  • Treats different sizes and shapes without set-up changes
  •  Automatic part detection signals treatment only when parts are in the treating chamber
  • System monitoring and fault detection ensure uniform treatment results

Advanced Technology

3DT is a leader in 3-dimensional surface treating systems. Our broad program of systems provide the ability to treat virtually any 3-dimensional polymer surface, regardless of shape, resulting in superior adhesion.

Surface Treatment of Catheter Tubing

The TubeDyne™ corona treating system is designed to improve adhesion on the outside of tubing and catheters.

Any tubing up to ¼ inch (6mm) in diameter, with or without metal inserts, can be placed in the holding fixture and receive uniform corona treatment at a length of approximately 2 inches (50mm).

TubeDyne is a compact, self-contained tabletop corona treating system which include an integrated generator, transformer, electrode assembly, holding fixture and ozone filter.

The system is PLC-controlled and features an operator console with a human machine interface (HMI), including monochrome display screen with status menu, run time log, service hour log and alarm/troubleshooting screen.

Please inquire about our custom systems for treating larger tubing and other specific requirements.

TubeDyne Advantages:

  • Improves surface tension on Pebax, PP, PE, nylon and more
  • Self-contained compact tabletop system
  • Improves bonding of catheter tube ends
  • Powerful, repeatable and uniform treatment

Treating Thick Materials IS Possible

3DT’s approach to corona treatment goes beyond 3-dimensional parts. Our advanced designs are capable of treating thick materials such as corrugated plastic boards and foam stock. In the past, these materials have presented numerous challanges. Now, 3DT makes it possible to treat these materials in a high-performance and efficient manner.

Surface Treatment for Wide, Thick Materials

At last, surface treatment is possible for wide and thick products such as foam stock, honeycomb boards, polymer panels and more. 3DT’s new, patent-pending HeliDyne corona treatment system is engineered to produce strong bonding on substrates for adhesive, printing, coating and laminating applications.

HeliDyne’s helix pattern of corona electrodes rotate while thoroughly treating material passed underneath. It accommodates materials with a thickness up to 1 inch and a width up to 80 inches. HeliDyne is fully customizible. It is equally effective for in-line applications and sheets cut-to-size. For these applications, HeliDyne can be engineered with a conveyor system.

HeliDyne’s numerous electrodes produce a wide corona band raising the surface tension and functionality of many materials. This system radically enhances the surface of materials for long-lasting, powerful adhesion and a higher quality end product.

Flexibility in Treatment Levels

Adjustable power levels play an important part when treating thin or sensitive polymeric substrates. 3DT’s PlasmaDyne Pro’s discharge is easily adjusted to accommodate various substrates, treating modes and applications. One system – numerous applications!


Radical Improvement in Bonding

PlasmaDyne ProTM generates atmospheric plasma to treat a wide variety
of materials improving the adhesion of ink, paint, and adhesives prior
to decoration, coating or the joining of parts. Our plasma technology
also offers the benefit of micro cleaning surfaces of contaminants and
residue. High-volume, in-line production is achieved verses slow and
laborious batch processing in a vacuum chamber.

PlasmaDyne ProTM produces a highly ionized plasma air stream that
restructures the chemical properties of material passed under its
treating head. The change is undetectable to the naked eye, but the
surface is now capable of powerful bonding with another material.
PlasmaDyne Pro is suitable for polymers, glass, metal, ceramic,
paperboard and composites.

PlasmaDyne Pro: Powerful, Smart, Versatile

  • Self-contained floor model can integrate into new or existing lines
  • Treats widths from 3/8” – 1 ½” (10mm – 40mm)
