Why Do Heat Transfer Printers Require Specialized Conveyor Belts?
The heat transfer printing process demands conveyor belts to operate continuously under high temperatures (often exceeding 200°C) and constant pressure. Conventional belts degrade rapidly in such harsh conditions, becoming brittle and prone to tearing. This leads to frequent downtime for replacements, increasing costs and severely disrupting production schedules.
Nomex® Aramid Felt Belts: Exceptional Performance Engineered for High Temperatures and Pressure
Nomex® is a meta-aramid fiber developed by DuPont, renowned for its outstanding heat resistance, mechanical strength, and dimensional stability. Felt belts made from Nomex® fibers are specifically engineered to meet the extreme challenges of thermal transfer printing.
1. Exceptional High-Temperature Resistance
Core Advantage: Nomex® fibers maintain stable performance under continuous temperatures up to 220°C (428°F) and withstand short-term peak temperatures as high as 250°C (482°F). This ensures the conveyor belt operates reliably beneath heated rollers without melting, carbonizing, or deforming.
Customer Value: Eliminates downtime caused by high-temperature belt damage, enabling uninterrupted continuous production.
2. Exceptional Dimensional Stability and Low Elongation
Core Advantage: Nomex felt belts exhibit extremely low thermal shrinkage and elongation rates. Under high temperatures and tension, they maintain precise width and length, effectively preventing misalignment, wrinkling, and slippage.
Customer Value: Ensures accurate pattern registration during printing, eliminates defects caused by belt shifting, and significantly improves print yield.
3. Outstanding Flexibility and Fatigue Resistance
Core Advantage: Even at greater thicknesses, Nomex felt belts retain excellent flexibility, conforming tightly to rollers to ensure uniform heat transfer. Their fatigue resistance enables sustained bending and stretching cycles, extending service life.
Customer Value: More even heat distribution yields superior printing results; Longer service life translates to reduced spare part and maintenance costs.
4. Superior Abrasion Resistance and Tear Strength
Core Advantage: The inherent high strength of aramid fibers enables Nomex felt belts to withstand friction against mechanical rollers and guides, as well as edge abrasion from fabrics.
Customer Value: Minimizes unexpected damage from surface wear or edge tears, ensuring production safety and stability.
