End seals that keep up with high-speed flexographic printing

Durable end seal solutions for reliable performance at high printing speeds

At elevated printings speeds, end seals have to withstand more friction and heat

Today's high tech printing technology allows increased printing speeds, frequently far beyond 400 m/min in medium to wide web printing. Such printing speeds demand a great deal of end seals, given increased friction and heat evolving in the process.

AGSflexo has specialized in the production of high-performance end seals for many years and is putting much focus on developing reliable end seal concepts that keep the chamber tight while offering an advanced lifetime even in challenging printing environments.

Anwendungsoptimierte AGSflexo-Dichtungen

coatSEAL Flexi-LF low friction end seals

coatSEAL Flexi-LF end seals with low-friction inlay

A stable but flexible seal body for optimum chamber fit with a low-friction inlay on the seal top where it touches the anilox roller to reduce friction heat on the seal. The benefit is lower evaporation of ink carrier liquid and less danger of ink built-up on the seal which could push up the doctor blades and cause leakage and/or irregular doctor blade wear.

coatSEAL Universal end seals for high-speed flexo printing

coatSEAL Universal 3D wear-resistant seals for all ink types

An extremely wear resistant and versatile molded rubber seal that fits all ink and coating types. Thank to the stable but flexible lip at the seal top, the seal keeps optimum contact with the anilox roller while having minimum contact surface. This reduces heat-related wear and ink accumulation, which pays off in terms of tightness and seal durability.

Impregnated felt end seals for flexo printing

coatSEAL Longlife B for water-based and UV inks

These felt end seals are pre-soaked with food-safe lubricant. The impregnation not only improves the anti-frictional properties of the seal but also has a ink-repellent effect which is particularly pronounced with water-based and UV inks
