PTFE (Polytetrafluoroethylene) conveyor belts are engineered for use in screen-printing tunnel dryers, where freshly printed textiles, posters, and decals must pass under infrared or forced-air heaters to cure inks without sticking or marking. Their non-stick surface ensures that wet or tacky prints release cleanly, delivering consistent throughput and perfect print quality on a wide range of substrates:
•Textile Screens: T-shirts, jerseys, bags, and home textiles
•Graphic Films & Decals: Adhesive vinyl, signage materials, point-of-sale graphics
•Ceramic & Glass Screens: Decorative tiles, glass panels
•Specialty Media: Glow-in-the-dark inks, reflective and metallic finishes
Key Features
•Non-Stick PTFE Surface
Guarantees zero adhesion of inks, preventing smudges, ghosting, or damaged prints.
•High-Temperature Resistance
Stable up to 260 °C (500 °F) for prolonged tunnel dwell times under infrared or hot-air zones.
•Low Friction & Smooth Conveyance
Minimizes drive power and wear on bearings; provides uniform belt speed for even curing.
•Chemical & UV-Resistant
Inert to solvents, cleaning solvents, UV stabilizers, and ink additives—maintains belt integrity.
•Seamless or Precision-Welded Options
True endless belts eliminate joints, or choose laser-welded seams with belt-body strength and no raised edges.
•Anti-Static Treatment
Optional conductive fibers or surface treatments to dissipate static build-up on synthetic substrates.
Manufacturing Technology
1.Vacuum-Impregnation Coating
Ensures homogeneous PTFE penetration into the substrate fabric, providing a durable, pinhole-free finish.
2.Reinforced Fiber Core
High-tenacity fiberglass or aramid yarns deliver superior tensile strength and negligible elongation, even under heavy loads.
3.Laser Seam Welding
Produces weld seams matching the base belt’s mechanical properties, with a perfectly smooth profile for snag-free operation.
4.In-Line Quality Control
Laser micrometers and vision systems continuously verify belt width, thickness, and surface uniformity to ±0.1 mm tolerances.
5.Optional Surface Treatments
Incorporation of antistatic or conductive additives during coating prevents dust attraction and static discharge in high-speed lines.
Benefits for Screen-Printing Drying Lines
•Zero-Defect Prints
Eliminate belt marks and ink bleed for the highest print clarity.
•Higher Uptime
Non-stick belt surface cleans instantly between runs; long service life cuts downtime.
•Energy Efficiency
Low friction reduces motor loads; stable high-temperature operation allows tighter heater spacing.
•Process Adaptability
Customizable belt widths, thicknesses, and edge profiles adapt to any tunnel dryer or print application.
