  Eltech`s 3D corona treatment system is perfect solution to adhesion problems on injection, blow moulded or extruded parts of PE, PP, PET, nylon, vinyl, polystyrene, polycarbonate, PVC, fluorocarbons and all other types of thermoformed and thermoset plastics. 3d jet corona can be used in a very flexible way, since a counter electrode is not needed. The discharge is ignited between a pair of electrodes inside the treatment tool and gets directed towards the substrate with a minor laminar air flow. This 3D corona treatment also eliminates grease, oils and other contaminants if any, which are most common adhesion retardants.3D surface-treating systems improve the bonding of inks, adhesives and coatings, allowing you to treat multiple surfaces and difficult configurations with remarkably consistent and convenient one-pass coverage.

AG Single bag to bag SHEET TREATMENT system to treat the non continues sheet/bags/woven sacks for FLEXO-OFFSET-SCREEN-LAMINATION-COATING manual machines. Materials like, self locking bag, Metalised laminated cardboard, pvc, polyester sheet, hm/ld/ sheet, woven sack bags (laminated / unlaminated, reverse bags, paper, conductive / nonconductive dupblex etc.CORONA TREATMENT increase the Surface bonding strength by creating Polar molecule on the surface. As a result excellent bonding of inks takes place. On untreated Plastic and paper, inks adhere on the surface by means of mechanical friction & are easily released by rubbing or adhesive Tape test. It needs the Surface tension to the surface more than (10dynes/cm) the surface tension of the printing inks/adhesives, etc... for bonding, coating, printing etc.. SALIENT FEATURES* Zero speed switch. Zero speed cut-off system, whenever silicon roller / motor speed comes down machine will automatically shut down, hence prevents the damage of silicon roller and increase the life of machine.* DC with motor with panel for Speed variation.* Audio-Visual alarm system* Ultra High Frequency* Compact design for comfortable to installation / operate / Quality* Soft Start.* Maximum Operator safety.* Treatment Roll with Silicon Sleeves.* High voltage side insulator on station for high voltage cable entry to avoid    short circuit problem.* Digital indication of corona current.* Force cooled converter for longer life.* Fully enclosed treater station.    Technical Specifications* Treat width capacity : 4" to 48 webs, Treater roll : 2"/3"* Idler roll : 2" / 3" diameter* Maximum line speed : 6 to 60 meter per minute.* Treat capability : One side* Mains supply : 230 V/440 V, AC ± 5 %, 1 Ø.* Mains frequency : 50 Hz ± 5 %* Output frequency : 15 to 25 Khz.* App. output power : 1/15/2 Kw.* Electrodes : INSULATED ROLL ELECTRODE

Eltech sheet corona treater is widely used to treat PP,PVC and metallised polyester laminated sheets to increase surface tension and gives better printing and adhesion. Water-based and UV inks printed on plastic films and other substrates create a need for the substrate to be treated prior to printing. Conventional method of roll to roll treatment is standard practice, but in Offset, Sheet corona treatment is required to increase surface tension or improve the printability. Some substrates are corona-treated when they are manufactured. Many of these substrates require a surface energy boost to match a particular ink or coating. This is done with corona pretreaters on the press just prior to the coating application point. PVC, PP, LD, Foam, Flex, metallized polyester, PE, OPP and other high-low density plastic materials should particularly be Corona treated to enhance the quality of the final product.

Corona treatment system is a very effective way to increase the surface tension of virtually any material. Surface treatment is required for plastic filmsfabrics whose normal surface tension is not sufficiently high to permit good wetting by flexo graphic inks. Corona treatment system increases the surface tension of the fabrics respective to inks by inducing molecular changes in the surface of the films. This is done by exposing the air at the material's surface to a high-voltage electrical discharge - a corona. Corona discharge treatment at atmospheric pressure for improving adhesion of various polymer substract is now standard practice. As shown in the diagram the fabric is passed from free roller through the airgap between multisegmented electrode and the silicon roller which generates continuous shower of ionised air called as CORONA.The electerode and dielectric cover on the roller serves as the electric connection to the stream of ionized air in the airgap.

    Nowadays a lot of substrate require surface  treatment for 3 dimensional substrates Presently the industry uses expensive treatment solutions which account for higher consumables and operating costs. Eltech through its R&Dhas indigeneously developed a treatment system to provide a solution to this problem.Thankfully it now possible to use this new technology.  PLASMA ION can effectively treat conductive as well as non conductive substrates. Plus it  consists of a High frequency power supply with an inbuilt  transformer and a plasma  nozzle . The nozzle comes  in various  shapes for effective treatment as per the requirement of the application. The nozzle can either be used manually or fitted on a robotic arm. In some applications more than 1 nozzle may be required .In such a case, ELTECH offers multiple plasma treating heads. This technology is suitable for high speed online as well as offline surface treatment and is extremely safe, cost effective and easy to use. Moreover it is a very clean and energy efficient technology since its operation requires dry compressed air which is  freely available.
