Our high-qualityphosphor bronze doctor blade is precision manufactured for high-speed, continuous and high-stability operation of global paper mills. Adopting imported high-purity phosphor bronze material, this blade features excellent toughness, uniform hardness, outstanding fatigue resistance and natural anti-corrosion performance. Different from ordinary steel blades that are easy to rust, deform and scratch rollers, phosphor bronze blades deliver stable mechanical performance in long-term humid, dusty and chemical-containing papermaking environments. The blade surface is smooth and dense with good self-lubricating property, ensuring clean pulp scraping, precise paper separation and no damage to dryer cylinders, rollers and other core equipment. It effectively eliminates paper breakage, streaks and surface defects, maintaining consistent production stability and greatly reducing frequent shutdown replacement and maintenance costs.
We provide full-size and full-parameter customized service for phosphor bronze doctor blades, fully compatible with all mainstream international paper machine brands and various papermaking processes. Our complete specification range covers standard and non-standard custom dimensions: conventional length 500mm–8000mm, width 20mm–120mm, thickness 1.0mm–6.0mm. We also support custom ultra-long, ultra-thin, wide-size and special-shaped blades for non-standard equipment. All core parameters can be precisely tailored, including blade flatness, edge angle, surface finish and hardness to match different machine speeds, pulp types and paper grades such as tissue paper, cultural paper, kraft paper and special paper. With high fitting accuracy, stable scraping performance and ultra-long service life, our phosphor bronze doctor blades help global paper enterprises reduce operating costs and improve finished paper quality.
