Keeping pace with the eco-conscious market trend, we fully support the application of water-based paints! Synthetic filaments, with their low friction, excellent coating performance, and cost-effectiveness, serve as an ideal substitute for traditional natural bristles. As the use of eco-friendly (water-based) paints continues to grow, more brush manufacturers are adopting synthetic filaments for brush production. Our filament filling machines, designed with enhanced stability and precision, effortlessly meet the challenges posed by new material characteristics while maintaining compatibility with a wide range of materials, driving the industry's transition toward sustainable manufacturing. Currently, our series of filament-filling machines is suitable for brush filaments, including natural bristles, blended bristles, and synthetic filaments.
