What Tantec A/S does

Tantec A/S is a privately held Danish industrial equipment manufacturer specializing in plasma and corona surface treatment systems for adhesion enhancement. Founded in 1974 and headquartered in Lunderskov, Denmark, with a wholly-owned US subsidiary (Tantec EST Inc.) in Glendale Heights, Illinois, the company designs and manufactures both atmospheric corona treatment systems and vacuum plasma treatment systems used to increase surface energy of low-surface-energy materials including plastics, metals, glass, ceramics, and elastomers. The product portfolio spans more than 28 named systems including VacuTEC vacuum chambers (four sizes), RotoTEC-X rotating electrode corona treaters, PlasmaTEC-X atmospheric plasma systems, ProfileTEC for automotive EPDM profiles, PlasmaLINE for medical devices, and a quality monitoring line (LeakTEC, MonTEC, Dyne test), all built on proprietary high-frequency, high-voltage discharge technology operating at 15-25 kHz and up to 80 kV. Tantec also offers aftermarket services including spare parts, on-site service, calibration, and operator training, and provides free in-house product testing to prospective customers.

Tantec sells globally through direct enterprise field sales from its two branch offices and a network of more than 30 channel partners and agents covering 14+ countries across Europe, North America, Asia-Pacific, Latin America, the Middle East, and Oceania, supported by participation in over 20 industry exhibitions per year and language-specific websites. Revenue is generated primarily through hardware sales of standard and customized equipment, supplemented by aftermarket service and consumables. Pricing is quote-based and tailored to customer specifications, with no public price list. The customer base spans medical devices (Coloplast, MGS Manufacturing, Fraunhofer IST), automotive and tier suppliers (Valeo, Autoform, ASD Lighting, Hill Machinery, VOLA), cable and pipe (Helukabel, Ducab, Flonidan), electronics (Sono-Tek, infinityPV), packaging (Captiva Containers, Kodan Plast), glass and optical (PSC A/S), and other industrial verticals. Tantec holds ISO 9001 certification and positions itself as a 50+ year specialist in surface treatment, with documented technical performance such as 2-10x improvements in lap-shear and peel strength on treated parts.

Three partnerships are on record, tiered core and minor.

Fraunhofer IST (Germany)coreStrategic or Co-development PartnerTantec has a long-term strategic partnership with Fraunhofer IST (Institute for Surface Engineering) in Germany. Fraunhofer scientists used Tantec's RotoTEC-X system to develop 'Plasma in a Bag' technology — a new low-cost technique for coating the inside of closed plastic bags by atmospheric pressure plasma for cell culture applications. The collaboration produced a prototype for automated, reproducible coating deposition under standard laboratory conditions maintaining bag sterility. Fraunhofer describes the cooperation as always beneficial to both companies.
PSC A/S (Denmark)coreStrategic or Co-development PartnerPSC A/S, a leading Danish manufacturer of optical filters and display windows with over 25 years of experience, partnered with Tantec to implement SheetTEC corona treatment for improved adhesion of printing inks on acrylic and polycarbonate sheets. Tantec designed a customized solution meeting PSC's requirements for both off-line (batch) and on-line production, with high treatment flexibility including adjustable speed, intensity, number of passes, and intuitive HMI interface.
