Rotary/Flat Screen Printing Machines: Serves as an ink/paste scraping blade to evenly remove excess color paste from the surface of screen rollers, ensuring sharp pattern definition and uniform color distribution.
Stenter/Tenter Frame Machines: Functions as a cleaning scraper to eliminate residual lint and paste from guide rollers and felt blankets, preventing roller adhesion and fabric contamination.
Material & Performance
Manufactured from high-precision stainless steel strips (e.g., 301/304 stainless steel or spring steel), featuring high elasticity, high hardness, and exceptional wear and corrosion resistance.
With a typical thickness of 0.1–0.3mm, the blade boasts a sharp edge and excellent toughness, enabling stable long-term operation under high-temperature and high-humidity conditions.
Form & Packaging
Supplied in coil form for easy cutting to custom lengths, perfectly compatible with squeegee holders of various machine models.
Packaged with foam inserts and carton boxes to protect the steel strip from damage during transportation and storage.
Product Advantages:
High Precision: Minimal dimensional tolerances and straight blade edges ensure consistent scraping or cleaning results.
Long Service Life: Exceptional wear and corrosion resistance reduce replacement frequency compared to ordinary rubber blades, lowering downtime and maintenance costs.
Easy Installation: Rolled packaging allows for on-demand cutting, enabling direct mounting into aluminum alloy squeegee holders compatible with mainstream printing/dyeing and heat setting equipment.
FQA:
Q: What is this doctor blade strip used for? A: It is a core component for rotary screen printing machines, designed to evenly scrape excess color paste from the surface of the rotary nickel screen.
Q: What material is this squeegee blade made of? A: It is made of high-grade stainless steel, offering excellent wear resistance, dimensional stability, and corrosion resistance to color pastes. Q: How does the blade quality affect the printing result?
A high-quality blade strip ensures aprecise and uniform pressureacross the entire rotary screen. This results in sharp pattern outlines, consistent color depth, and prevents common defects like "color bleeding" or uneven ink distribution on the fabric.
Q: What sizes and thicknesses are available for order?
A: We provide a wide range of standard thicknesses (e.g.,0.1mm, 0.15mm, 0.2mm) and widths to fit various squeegee holders. Our strips can be supplied in rolls or pre-cut to specific lengths according to your machine's requirements.
Q: How can I ensure the blade strip doesn't damage the nickel screen?
A: Our blades featureprecisely polished edgesand consistent straightness to minimize friction against the rotary nickel screen. To prolong screen life, we recommend selecting the appropriate blade thickness based on your mesh count and printing paste viscosity.
