Why Fluorine-Free?

Traditional coating processes sometimes rely on fluorine-containing compounds to achieve certain non-stick or water-repellent effects. However, fluorine-based chemicals can raise environmental and health concerns during manufacturing and disposal. By switching to a fluorine-free powder coating system, we eliminate those risks while still delivering a high-quality, durable finish.

Key Benefits of the New Line

1. Eco-Friendly Production
   · No fluorine compounds means lower VOC emissions and reduced hazardous waste.
   · The powder coating process itself generates minimal overspray waste, and any overspray can be collected and reused.
2. Superior Surface Quality
   · Our new automatic line ensures consistent coating thickness, even on complex tumbler shapes.
   · The finish is smooth, scratch-resistant, and available in a wide range of colors and textures — from matte to hammer tone.
3. Increased Capacity
   · Fully automated from part hanging to curing oven, the line operates continuously, boosting our daily output by over 40%.
   · Faster turnaround times for bulk orders without compromising quality.
4. Safer for End Users
   · Fluorine-free coatings contain no PFAS or other persistent chemicals, making our thermoses safe for daily food and drink contact.
   · The coating withstands high temperatures and repeated washing without degrading.

How It Works

1. Pre-treatment: Tumblers are cleaned and chemically etched to ensure perfect adhesion.
2. Automatic Spraying: Electrostatic powder spray guns apply the fluorine-free powder uniformly as the cups rotate on a conveyor.
3. Curing: Coated cups pass through a high-temperature oven where the powder melts and fuses into a tough, smooth film.
4. Quality Check: Automated thickness gauges and human inspection confirm every batch meets our standards.

What This Means for Our Customers

· Greener supply chain – Meet your own sustainability goals with our verifiable fluorine-free process.
· Consistent aesthetics – No more variations in gloss or texture between production runs.
· Faster lead times – The automatic line reduces manual handling and bottlenecks.
