3DT: Trailblazing Surface Treatment Company Celebrates 25 Years

FTA  August 2016

Germantown, WI   3DT LLC, true pioneers in plasma and corona treatment, celebrates their 25th Anniversary August 1.  In 1991 electrical surface treatment was an emerging technology in the United States. Two young Danish businessmen, Morten Jorgensen and Erik Kiel, brought corona and plasma technology from Denmark where it was invented by engineer, Verner Eisby in the 1950s and later adapted to the treatment of 3D parts by Bent Sorensen in the 1970s.  FSE02_MSET

In the 1990s most automotive, medical and packaging manufacturers were using chemical primer baths, physical abrasion and flame treatment to increase the surface tension and bonding on 3D parts. The drawbacks of these methods were huge, including being environmentally and health hazardous and costly. As a result, the new, safe, quick and less labor-intensive corona treatment took off, particularly with 3DT’s reliable and highly effective equipment.

Today, 3DT produces a complete line of surface treatment systems developed to manage adhesion problems on nearly all substrates and configuration of parts. 3DT covers the spectrum in surface treatment solutions from microcleaning Petri dishes for cell growth to improving the adhesion of flocking on rubber profiles. Their systems range from compact tabletop units to mammoth 10 treating head systems. 3DT’s worldwide success for 25 years lies in their innovative technology, robust design, reliable results and exceptional customer service provided with every standard and custom system.

Completing their line of solutions, 3DT represents two German companies for North America: SOFTAL and AFS. Both firms are powerhouses in the film manufacturing and converting industries.  Whether an application is 10 inches or 10 meters, there is a surface treatment solution at 3DT.  Currently, 3DT is experiencing favorable growth in this area of the market due to high quality German engineering and 3DT’s local, expert sales and service.

At their 16,000 square foot facility in Germantown, Wisconsin, Erik Kiel, owner, looks forward to the next decade where 3DT “will be launching new, exciting technology.” He attributes 3DT’s longevity to the company’s ability to be flexible, adjusting to consumer and market trends, a team approach between all employees, and a strong customer focus. Kiel concluded by stating, “We appreciate the loyal customers and employees who have helped us achieve this important milestone.”

AFS Modular GeneratorsMinimizing Downtime

AFS experts discuss the advantages of modular generators for corona and plasma treatment stations

Corona stations are available in all sizes depending on the application- from 10 inch narrow web lines to wide coating machines and BOPP/BOPET lines of up to 10 meters. Usually, the high frequency high voltage that is needed to power the corona process is provided by generators that have to be upsized with increasing performance requirements.

However, their maximum performance is limited due to the maximum available size of the electrical components in the power inverters. With the maximum performance available on the market – 60kW per generator – and therefore per electrode bar, the limits of the technical possibilities are reached. Not only on extremely wide lines but also at high speed applications or for materials with high demands in terms of corona dosage.

Scaling for pretreatment by means of additional electrodes and a single generator quickly becomes expensive due to larger or additional rollers. A further disadvantage of these large single generators is that a technical defect at a critical part of the inverter can bring an entire web to a standstill.

Overcoming limitations

AFS, from Horgau, Germany, now offers a modular generator design as a solid solution to both problems. AFS’ modular generator overcomes the performance limitations of a single generator and, at the same time, minimizes failure rate.

These generators boast several parallel power inverters, which increase the maximum performance of a single generator to 144kW – more than twice as much as conventional products on the market.

Consequently, modular generators are capable of setting new performance records and are perfectly suited for the power needed for processes with controlled gas, such as plasma treatment systems.

If a module fails, the generator will still operate but with a reduction in power until the module is replaced by a new one – simply “plug and play.” Single modules are identical and thus interchangeable. Clearly, modular generators reduce production line downtime and costly trips by onsite service specialists.

During the development of their modular generator technology, the experts at AFS included the most sophisticated components available, such as a larger TFT color touch screens which employ an intuitive user-interface on the generator similar to the graphics and functions of smartphones and tablets. Operational settings can now be adjusted through the proven rotary knob as well as by means of a touch screen. Additionally, system parameters can be easily adjusted through a password protected area for specific applications.
