TRESU’s new D3P carbon fibre chamber doctor blade

Flexo equipment and machine manufacturer TRESU introduces the D3P carbon fibre chamber doctor blade, enabling quality assured, high-speed printing with reduced manual intervention for mid-web applications such as paperboard and flexible packaging.

Available for printing widths between 1200mm and 3000mm, the D3P chamber has a corrosion-resistant carbon fibre composition that is significantly lighter weight than aluminium alternatives, making handling easier and shortening setup times.

The D3P’s design provides an enclosed environment for ink flow, to enable clean, consistent printing at speeds of up to 800m/min. The chamber comes with TRESU’s rubber seal system that automatically maintains ink at constant pressure levels. It is optimally positioned for doctoring on anilox roll diameters that are common with mid-web applications. These features eliminate the risk of leakage and air contamination during production, providing perfect, blister-free print with fast drying characteristics and improved gloss values, at faster speeds.

Ink flow is further optimised thanks to the chamber’s ink-repellent surface, which also facilitates easier cleaning during ink changes. Additionally, its ‘P-Line’ pneumatic clamping system allows fast, safe blade changes.

As with TRESU’s MaxiPrint Concept, the D3P chamber can be fitted with an integrated water nozzle for fast and efficient self-cleaning. Alternatively, it may be connected with TRESU’s F10 iCon ink supply system that assists in controlling flow, pressure level, colour density and washing.

Constructed as a single piece by resin transfer moulding, the D3P also offers durability to withstand high printing speeds and high-pressure ink flows.

Henrik Kristensen, vice-president, TRESU Ancillary and Customer Care, comments: “The D3P chamber makes an important contribution to mid-web flexo print quality and production efficiency. With its light-weight form, the chamber may be easily retrofitted with existing presses or integrated, as an added-value feature, in the latest designs of OEM presses.”
