Squeegee Blade Component – Machinery and Equipment Manufacturing

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
