Doctor blade chambers

Epsilon Composite’s doctor blade chambers are a superior alternative to traditional solutions (aluminium, prepreg composites or RTM).

Faster, lighter, stiffer

Demonstrating a high level of engineering capabilities and expertise in composite manufacturing, EPSILON COMPOSITE has developed a complete range of doctor blade chambers, with applications in printing, non-woven textiles and films.

Carbon doctor blade chamber for Flexo machines

The aluminium doctor blade chamber often appears to be a puzzle for the flexo printer:

  • Very limited mechanical performance for large printing widths
  • Difficult handling due to the heavy weight for wide printing width machines
  • Corrosion caused by inks/cleaning agents
  • Ink leaks and long cleaning times

The Epsilon carbon doctor blade chamber solution meets all the needs and challenges of flexo printing

Mechanical performance
The main carbon profile, the heart of the system, is obtained by pultrusion of carbon fibers.
Pultrusion is the only process that combines high mechanical performance, dimensional and geometric stability, and productivity.
The high level of stiffness of the carbon profiles significantly contributes to the limitation of bouncing.
Handling
Epsilon doctor blade chambers are significantly lighter than their aluminium equivalent (-50% on average).
Handling can be done safely and requires less physical effort, and fewer personnel and technical means.
Corrosion
Unlike aluminium, Epsilon carbon elements are perfectly resistant to corrosion brought about by inks and chemicals commonly used in flexography.
The use of high quality epoxy resins ensures the protection of the functional surfaces of the doctor blade chamber. No additional surface coating is required.
All other components (stainless steel, polymers) are corrosion resistant.
Waterproofing
Numerous machine tests have made it possible to develop the most effective solutions and components in terms of waterproofing.
The Epsilon doctor blade chamber helps to limit material losses and long cleaning times for the doctor blade chamber (thanks to its specific carbon surface) and the surrounding structure (machine frame).
