Introducing 3DT’s Surface Treatment System 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, patented 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 corona treating the material passed underneath. HeliDyne accommodates materials up to 1 inch thick and up to 80 inches wide. The system is equally effective for inline applications, as well as sheets cut-to-size.  For these applications, HeliDyne is engineered with a conveyor system.

Conveniently, HeliDyne is prepared for integration into your production line with an Allen Bradley PLC and a Maple Systems HMI for easy, complete, recipe-based operation and monitoring.

HeliDyne’s numerous electrodes produce a wide corona discharge band raising surface tension and functionality of many materials, such as porous, hollow, and over-size materials. As with all of 3DT’s systems, HeliDyne is built with superior craftsmanship and proven technology in Germantown, Wisconsin.
