Nordson has decades of experience and can precisely control the width, fiber size, and density of spiral dispensing, thereby achieving high-quality bonding processes. The spiral glue pattern can save adhesive while maintaining sufficient adhesion and assists customers with cost savings.
Overview
PUR dispensing solution in shoe making: Revolutionizing Sole Bonding Through Advanced Adhesive Technology
PUR (Polyurethane Reactive) dispensing system represents a groundbreaking shift in footwear assembly, fundamentally disrupting traditional sole bonding methods. This innovative process leverages the unique properties of moisture-curing reactive hot-melt adhesives applied via precision spray systems, enables superior performance, sustainability, and manufacturing efficiency across modern footwear production.
Problems with Traditional Brush Gluing Process
- Inconsistent gluing quality, prone to de-bonding
- High operational temperatures and strong adhesive odors, pose occupational health risks
- Labor-intensive, low production efficiency, and high labor costs
- Environmental pollution caused by the gluing process
Why Use PUR Reactive Hot-Melt Adhesives
- Significantly increased production efficiency, 2-3 times that of traditional methods
- Exceptional bonding strength
- Environmentally friendly, solvent-free
- No need to treat the shoe upper with water or glue
Value Propositions
- More suitable for mass production
- Labor savings
- Process simplification
- Energy savings
- Equipment savings
- Capable of achieving automation
