Kolding, Denmark - At Sino Corrugated 2017, TRESU Group (stand N2A123a) will showcase its carbon fibre chamber doctor blade and ink supply systems for enhancing efficiencies, productivity and quality in corrugated flexo printing (Shanghai New International Expo Centre, Shanghai, China, 11-14 April). Available for printing widths in excess of six metres, TRESU’s ancillary solutions offer the advantages of faster, automated, enclosed ink flow and circulation, with minimum waste.
Automated ink regulation and cleaning with the F10 iCon ink supply system
The F10 iCon ink supply system regulates ink flow, pressure and viscosity from the bucket to the flexo press, thereby maintaining constant, predetermined ink density values throughout production runs. Additionally, when ink changes are required, the supply system provides fast, thorough automatic cleaning of the chamber, and returns almost all unused contents to the bucket for reuse in subsequent jobs. The F10 iCon provides simultaneous ink change cycles on printing stations in minutes, resulting in significant time and materials savings per job.
Chamber doctor blade programme: uniform quality print and easy handling
TRESU’s chamber doctor blade systems, especially when used in conjunction with the F10 iCon ink supply system, offer further efficiency and quality benefits.
The TRESU chamber programme includes lightweight, corrosion-resistant carbon fibre and ceramic variants and covers all flexo printing situations, including printing widths exceeding 6000mm (236in) often seen in corrugated printing. Featuring the company’s patented seal system, TRESU chamber doctor blades prevent leakage and air contamination, thereby ensuring clean, blister-free print result with fast drying characteristics, better reflection and higher gloss values. When doctor blades need replacing, TRESU’s patented clamping systems enable changeovers in less than two minutes.
For wider widths particularly, the carbon fibre chamber doctor blade range offers easier handling including portability thanks to their light weight. Furthermore, their top-coated ink-repellent surface protects against detergents and adhesives with pH values of 9.0 and above, and makes cleaning easier. Curved inner surfaces maximize volume and facilitate controlled discharge.
MaxiPrint Chamber Concept for fastest cleaning cycles
Alternatively for web applications between 1600mm and 6000mm, the MaxiPrint Concept is a light-weight carbon-fibre or ceramic chamber, with integrated inking and cleaning systems, for fastest cleaning cycles. The chamber and anilox roll are automatically cleaned thanks to an integrated cleaning nozzle with a robust water-shot mechanism that maintains a low pressure to limit water loss. Relatively fast emptying occurs because ink or coating fluid is evacuated through both the chamber’s inlet and outlet. The ink change and cleaning cycle is typically completed within approximately five minutes.
Based in the Chaoyang District of Beijing, TRESU’s China subsidiary offers fast-response technical support, and smooth management of ink supply retrofitting projects that can significantly enhance the performance of existing printing lines.
Gray Chang, sales and technical manager, TRESU China comments: “For China’s packaging suppliers, achieving greater process efficiency is of paramount importance, in order to control rising production costs, especially with respect to labour, in an uncertain economic climate. Flexo offers a competitive alternative, especially in corrugated preprint production, with its the high standards of quality and relatively low consumable costs. TRESU’s controlled ink supply solutions with light-weight, durable carbon fibre chambers are ideal for meeting the market’s challenges - automating and eliminating waste from the process, while providing the basis for higher print speeds without compromising quality.”
