Tresu Group emphasized its capability as a total flexo solutions provider at Sino Corrugated 2015, China from 14 to 17 April, with an offering that comprises ancillary products for ink and varnish flow control, integrated printing and coating units, and complete multi-station lines for packaging and lottery tickets. Stand highlights will include the unveiling of the modular ‘Concept’ press, the light-weight corrosion-resistant carbon-fibre chamber doctor blade, and the F10 iCon ink supply system.
Tresu’s webfed modular flexo ‘Concept’ printing
Customized to end-user performance requirements and built with Tresu’s 30 years of press building and engineering expertise, the Concept offers a flexo platform in 900 mm, 1,100 mm and 1,400 mm widths. In addition, it provides the possibility for seamless integration of processes, such as variable data, gravure, screen, hot and cold foil and finishing, providing an end-to-end solution for highvalue packaging. Running at speeds of up to 600 metres a minute, the Concept can convert substrates up to 600 micron thickness, including paper, board, aluminium foil and flexible packaging.
Allan Sander, vice-president of Tresu Solutions, says, “China’s packaging converters face growing demand for shorter runs as well as high quality from brand owners and retailers. In-line flexo provides the most effective way of offering service flexibility while maintaining the competitive edge in terms of productivity, waste reduction, footprint and ergonomics.”
Lightweight carbon fibre chamber doctor blade
Tresu’s full range of ancillary solutions, comprising chambered doctor blades, supply systems and chilling equipment, offer full, automated, enclosed ink circulation, at controlled flow, pressure and viscosity. A highlight of the Tresu stand is the new programme of lightweight carbon fibre chamber doctor blade systems, which offer improved chemical resistance, optimized flow and safe, easy handling in virtually all flexo printing situations.
Enclosed chamber technology to enhance process control
Common to all Tresu chamber doctor blade systems are the company’s patented seal systems and two-minute blade change capability. As well as being integral to the Concept, Tresu’s ancillary equipment is a feature of the flexo presses of many original equipment manufacturers. The enclosed environment, resulting from the seal and precise blade positioning, ensures pressure and flow rate are maintained at desired levels without manual intervention. This stops air contaminating the chamber and results in foam-free transfer of ink and coating directly to the anilox cells, also at fast speeds. The enclosed chamber also prevents solvents from escaping and protects the ink from degradation due to exposure to the atmosphere.
F10 iCon ink supply system
For common impression flexo printing situations, the F10 iCon ink supply system automates ink pressure and viscosity in flexo printing machines. This, in turn, ensures a constant, accurate ink density on the printed substrate and prevents air from contaminating the ink chamber. The energy-efficient system also provides thorough fully automatic cleaning, removing ink and residue from the chamber, achieving a complete ink change cycle in five to ten minutes.
