PU Seal End Seal Square Cross Section for Flexo Printing Chamber Systems
Product Overview

The PU Seal End Seal with square cross-section shape is a high-performance sealing component designed for flexographic printing chamber doctor blade systems. It plays a critical role in preventing ink leakage and maintaining stable ink circulation within the chamber.

In flexographic printing machines, the doctor blade system controls the amount of ink applied to the anilox roller. The end seal is installed at both sides of the ink chamber to prevent ink leakage and ensure consistent ink flow during high-speed printing operations. A well-designed end seal significantly improves printing efficiency, reduces ink waste, and prolongs the lifespan of both the doctor blade and anilox roller.

This PU end seal with square cross-section is made from high-quality polyurethane material, offering excellent wear resistance, flexibility, and chemical resistance. The seal is engineered to withstand continuous contact with the anilox roller while maintaining reliable sealing performance.

Designed for modern CI flexographic printing presses, the PU end seal is widely used in packaging printing, label printing, and coating applications.


Key Features of PU Seal End Seal
High Performance Polyurethane Material

The end seal is manufactured using premium polyurethane (PU) material, which offers:

  • excellent abrasion resistance
  • strong elasticity
  • long service life
  • resistance to printing inks and solvents

Polyurethane materials are widely used in industrial sealing components due to their durability and flexibility.

Square Cross Section Design

The square cross-section shape provides better sealing contact between the ink chamber and the anilox roller.

Benefits include:

  • improved sealing performance
  • reduced ink leakage
  • stable ink circulation
  • consistent printing results

This geometry also ensures uniform pressure distribution during operation.

Excellent Chemical Resistance

The PU seal end seal is compatible with various printing inks, including:

  • water-based inks
  • solvent-based inks
  • UV inks

Its chemical resistance ensures reliable operation in different printing environments.

Long Service Life

The wear-resistant polyurethane structure reduces friction and extends the service life of the seal. This minimizes machine downtime and reduces replacement costs for printing companies.


Applications
Flexible Packaging Printing

Used in CI flexographic printing machines to seal the ink chamber during high-speed printing operations.

Label Printing

Ensures clean ink transfer and prevents ink leakage during label printing production.

Corrugated Board Printing

Suitable for carton and corrugated packaging printing equipment.

Industrial Coating Equipment

Can also be used in coating and laminating machines that utilize chamber doctor blade systems.
