The Ultimate Guide to Choosing a Nomex Belt for Heat Press & Heat Transfer Machines


If you run a heat press or a heat transfer conveyor machine for sublimation, screen print curing, or HTV (heat transfer vinyl), you know the conveyor belt is the most abused component. It sits under 400°F (204°C) of direct heat, 24/7.

Standard cotton or polyester felts burn, shrink, or stretch. Nomex is the industrial standard—but not all Nomex belts are created equal.

Introducing the Annilte Nomex Belt for Heat Press. Engineered for the punishing environment of automatic heat transfer machines, this belt delivers consistent tension, flat product tracking, and flame resistance that standard felts cannot match.

Why Nomex? The Heat Press Operator’s Pain Points

Pain Point #1: Belt Shrinkage & Tracking Issues
After 100 hours of use, standard felt belts shrink. The machine’s tracking sensor goes crazy. You spend 20 minutes every morning re-aligning the belt.

  • Annilte Solution: Nomex (Meta-Aramid) has a thermal shrinkage of less than 1% at 400°F. Your belt stays true, your prints land exactly where they should.

Pain Point #2: Lint & Residue Transfer
Nothing ruins a white polyester shirt like black lint falling from a burnt conveyor belt. Standard belts carbonize over time, depositing debris onto your heat transfer film.

  • Annilte Solution: Annilte Nomex belts are engineered with a closed, smooth surface that resists lint shedding. The belt remains clean, keeping your substrates spotless.

Pain Point #3: Edge Fraying (The “Razor Blade” Effect)
Heat press conveyors use metal edge guides. Standard felts fray within weeks. Those frayed fibers wrap around the roller bearings, causing motor burnout.

  • Annilte Solution: Our Nomex belt features reinforced, laser-cut edges that resist unraveling. The high tensile strength (up to 2000 N/50mm) ensures the belt pulls evenly without edge stress.
