Enulec offers custom designed solutions to electrostatic related problems. The product range includes highly effective and innovative ESA systems (standard top loading, maintenance free top loading, core charging and side loading systems) which have helped customers in the gravure printing industry to achieve high quality print standards along with high productivity and maximum standards of safety. In addition to this, EST electrostatic discharging systems assist customers in the printing and plastics processing industries to successfully eliminate static charges in machines such as winders, slitters and laminating machines, so ensuring smooth and safe production processes.
ENULEC Electrostatic Printing Assist systems are used by many of the world’s leading gravure printers and machine manufacturers of flexible packaging, tobacco packaging, décor and colour print for publication to improve and maintain the highest standards of print quality by creating the conditions for optimum ink transfer and eliminating “missing dots, dot skips”. They are suitable for use with water based and non metallic solvent based inks when printing on paper, board and plastic film substrates. They are tested and certified to the latest ATEX safety standards and are characterized by their reliability, their low maintenance design and their user friendliness.
Gravure printing is characterized particularly by its outstanding quality of print which has been further improved by the Enulec ESA Top Loading system leading to the establishment of new standards. The main feature of the Special Top Loading system is a virtually maintenance- free, air assisted charge bar, previously unknown in the gravure packaging printing industry. Compared to the charge bars with open arrays of charging pins used in the past, this new and innovative technology offers the benefit that frequent cleaning is no longer necessary. This is achieved due to a special charge bar construction in which the charging pins are bedded completely into a small tube where they can not be contaminated by particles of ink or dust. Purged by slightly pressurised air a build up of dirt due to ink or substrate dust is prevented. In introducing this innovation, particular attention was paid to overcoming the various weaknesses associated with conventional ESA top loading systems with exposed charging needles, particularly as these relate to safety. Included among such weaknesses is the need for unwanted machine stops which are necessary due to the need for frequent and regular charge bar cleaning.
The ENULEC Inline Static Measurement System offers new possibilities for process optimization and an increase in safety during production. Substrates of all types are analysed for electrostatic charge in an inline process and the results so measured are recorded. When a pre-selectable warning threshold has been reached, the system provides a signal to the operator and provides information concerning the critical state of any static electrical charge which is present. The equipment further provides a signal contact to the machine control so offering optimum control over the production process.
