Component Specifications

Definition
The squeegee blade is a critical component of the squeegee assembly in screen printing machinery, responsible for precisely controlling ink deposition by applying controlled pressure and angle during the printing stroke. It ensures uniform ink transfer through the screen mesh openings onto various substrates while maintaining consistent print quality and registration accuracy.
Working Principle
Operates on the principle of controlled deflection and pressure application: as the squeegee assembly moves across the screen, the blade deforms slightly to create a sealing line that forces ink through the mesh openings. The blade's durometer, angle, and edge geometry determine ink release characteristics and print definition.
Materials
Polyurethane (typically 60-90 Shore A durometer), sometimes with additives for wear resistance and chemical compatibility. Alternative materials include rubber compounds for specific applications.
Technical Parameters
  • Height 25-50mm
  • Length Customized to machine width (typically 500-2000mm)
  • Durometer 60-90 Shore A
  • Edge Type Square, round, or beveled
  • Thickness 6-12mm
  • Operating Temperature -10°C to 80°C
Standards
ISO 2846-1, DIN 16611
