Surface Treating

Most plastics are naturally nonpolar and typically carry additives and demolding agents on their surface so that inks, coatings, or adhesives don’t easily stick to them. For example, inks and paints often just run off newly thermoformed or molded parts that have inert, nonporous, low-energy surfaces. Surface treatment of 3-D parts facilitates high quality printing, allows for clear readable markings on the surface and improves the adhesion of labels and coatings.  INPRO Technologies represents a line of surface treatment equipment manufactured by Enercon Industries www.enerconind.com. Enercon offers various technologies for the in-line treatment of 3-D parts, all of which offer an economical alternative to chemical primers, batch treatment or use of specialized coatings & adhesives.

Air Plasma (Corona)

Enercon’s Dyne-A-MiteHP is a powerful and economical way to improve surface adhesion on 3-D parts. Air plasma is formed by blowing atmospheric air past high-voltage powered electrodes and is sometimes referred to as corona treatment. The electrical discharge positively charges the ion particles surrounding it. Through direct contact, these particles positively charge the treated area of the object’s surface. This makes the surface more receptive to any applied substance, including inks, coatings or adhesives. The Dyne-A-MiteHP’s unique design generates an aggressive blown arc discharge that is ideal for higher line speeds and demanding applications. It is available as either a single or double head unit, depending on the surface area to be treated. Ideal for PE, PP, PET, nylon, vinyl, polystyrene, polycarbonate and PVC, the Dyne-A-MiteHP is easy to use and inexpensive to operate.

 

 

Chemical Plasma

Variable chemistry plasma (VCP) is formed using basic principles found in air-plasma and flame-plasma treatment. Much like an air-plasma field, a chemistry plasma field is generated in an electrically charged atmosphere. Instead of air, this method relies on other gases, typically argon or helium, that deposit various chemical groups on the substrate surface to improve its surface energy. Variable chemistry plasma treatment is essentially a fine etching process that provides different surface characteristics depending on the gas chemistry employed. Enercon’s Dyne-A-MiteVCP systems are the most gentle and advanced of the technologies and are ideal for delicate and hard to treat materials.

Blown Ion Discharge

Blown-ion air plasma systems push pressurized air past a single electrode which discharges inside the treater head. The eletrode creates positively charged ions in the surrounding air particles. The air pressure forces the air particles to accelerate out of the tip of the head as a high-velocity stream of charged ions directed toward the substrate surface. Through direct contact, these particles positively charge the object’s surface, increasing its surface energy and making it more receptive to inks and coatings. Air plasma is a popular surface-treatment technology because it is effective, easy to use and inexpensive to operate. In addition to treating a variety of plastics, the Dyne-A-MiteIT is ideal for the treatment of conductive surfaces, electronic parts, and glass.

Flame Plasma

A plasma field is formed when flammable gas and air are combined and combusted to form an intense blue flame. Brief exposure to the energized particles within the flame affects the distribution and density of electrons on the substrate’s surface and polarizes surface molecules through oxidation. This method also deposits other functional chemical groups that further promote ink wetting and adhesion. Enercon’s Dyne-A-Flame treater generates more heat than other methods, but creates greater surface energies with longer shelf life. Flame treatment is commonly used to process injection and blow-molded parts because of the thickness, size and shape of the parts.

Narrow Web Treaters

Enercon Industries offers both standard and custom designs for narrow web corona treating. The XL series compact treater fits virtually all narrow web presses. A clamshell design facilitates easy web threading, and hinged and slip-off electrode cartridges can be easily removed, making cleaning and maintenance a breeze. No tools, disassembly, realignment or air gap adjustment is required. The power supply is built right into the station and ducting for ozone removal has been positioned to maximize operator work space. This series is available in 10”, 14” and 18” treat widths. The TL series treater combines the power supply and treating station into one easy-to-install unit. The treatment capability and reliability is identical to the TLMax, only the packaging has changed. The TLMax series is available in 10”, 14”, 18” and 22” treat widths.
