Product Introduction: Soldered Steel Reed

Product Name: High-Precision Soldered Steel Reed for Textile Machinery
Core Technology: Low-temperature tin-soldering process + precision steel strip alignment

1. Product Overview

The soldered steel reed is a critical component in modern high-speed looms (e.g., air-jet or rapier looms), designed to guide and space warp threads with micrometer-level accuracy. Unlike traditional riveted or welded reeds, our soldered design minimizes thermal distortion, ensuring consistent fabric quality even at 1,000+ RPM operating speeds.

2. Technical Advantages

• Precision Soldering Technology:
  • Adopts low-temperature tin-silver-copper (Sn-Ag-Cu) alloy soldering, with melting point controlled at 217°C ±5°C.
  • Eliminates warping risks from high-temperature welding, maintaining reed flatness ≤0.05mm/m.
• Material & Structure:
  • Steel strips: High-carbon spring steel (e.g., SK5), hardness HRC 45-50, wear-resistant and corrosion-resistant.
  • Solder joints: Uniform, void-free, and smooth-edged to prevent thread snagging.
• Performance Benefits:
  • Reduces fabric defects (e.g., weft skip, tight spots) by up to 30%.
  • Extends reed lifespan by 2x compared to riveted counterparts.

3. Quality Control

• In-Process Inspection:
  • Laser alignment verification after soldering.
  • 100% flatness testing under 10kg/cm² pressure.
• Final Testing:
  • Simulated loom operation at max speed for 24 hours.
  • Salt spray test (ASTM B117) for 96 hours to validate corrosion resistance.

4. Customization Options

• Dimensions: Width (50-3,200mm), density (10-45 dents/cm), and profile (flat/curved) tailored to loom models.
• Surface Treatment: Optional Teflon coating for reduced friction or nickel plating for enhanced durability.

5. Applications

• Textile Types: Light-to-heavy fabrics (e.g., denim, canvas, technical textiles).
• Machinery Compatibility: Compatible with Picanol, Toyota, Itema, and other major loom brands.
