TANMNG
Due to its superior mechanical properties and customizable advantages, ceramic coated paper machine doctor blades are widely recognized and applied in the global paper industry. They effectively boost production efficiency, stabilize running performance, and significantly improve finished paper quality.Our ceramic doctor blades support full custom sizes and condition-based ceramic coating solutions, perfectly matching different paper machine speeds, tension conditions and on-site working environments. After extensive on-site running tests, our blades have gained consistent positive feedback from global paper mill customers.
1. Extreme Wear Resistance & Long Service LifeCeramic coatings feature ultra-high hardness and outstanding abrasion resistance, far exceeding traditional metal blades. The precisely maintained sharp cutting edge ensures stable scraping performance under high-speed and high-pressure operating conditions. It greatly extends service life, reduces blade replacement frequency, and effectively cuts down maintenance costs and unplanned downtime.
2. Excellent Corrosion ResistanceWith stable chemical inertness, the customized ceramic coating resists acid, alkali and pulp medium erosion. It does not rust or degrade in humid and corrosive papermaking environments, maintaining consistent scraping stability for long-term continuous production.
3. Ultra-low Friction & Smooth Paper SurfaceThe ultra-smooth ceramic surface provides optimized low-friction contact with paper webs. It effectively reduces paper tearing, fiber pulling and web breaking, greatly improving paper flatness, finish and overall appearance quality.
4. Superior High-temperature StabilityCustom ceramic coatings maintain stable physical properties under long-term high-temperature working conditions. They resist thermal deformation, oxidation and high-temperature fatigue, ensuring reliable performance in dryer sections and high-temperature production environments.
5. Precise Scraping & Leveling PerformanceHigh-hardness ceramic coating delivers ultra-sharp and uniform scraping force. It achieves fine cleaning, uniform leveling and effective residue removal, optimizing paper edge uniformity and reducing paper defects.
6. Full Customization for Size & CoatingWe provide complete non-standard customization of blade length, width, thickness and edge angle. Meanwhile, ceramic coating thickness, density and surface roughness can be tailor-made according to actual machine speed, temperature, pulp impurity content and corrosion level, achieving the best matching effect for different production lines.
7. Environmental & Green ManufacturingHigh-stability ceramic coatings greatly reduce fine metal particle pollution caused by blade wear, lowering environmental emissions and complying with modern eco-friendly manufacturing standards.
8. Excellent On-site Performance & Positive Customer FeedbackAll customized ceramic doctor blades support on-site trial operation. Mass installation feedback shows that our ceramic blades run stably without scratching, jumping or residue accumulation. They effectively reduce paper defects and frequent shutdowns. Many customers report that the service life is 3–5 times longer than traditional blades, bringing obvious cost reduction and production improvement with high repurchase rates.

High-precision Polished Ceramic Coating | Ultra-smooth surface, ultra-low friction, no burrs | High-speed production, thin paper, high surface quality requirements | Thin paper, specialty paper, coated base paper | No paper scratching, no fiber pulling, improve paper smoothness and yield |
High-temperature Resistant Ceramic Coating | Thermal stable, anti-thermal fatigue, no deformation under heat | Dryer section, long-term high-temperature working area | All high-temperature molding paper types | Avoid high-temperature failure, ensure continuous and stable scraping |
Heavy-duty Reinforced Ceramic Coating | Super wear-resistant, anti-impurity scouring, strong adhesion | High-impurity pulp, 24h continuous heavy-duty production | Recycled paper, carton paper | Resist particle scouring, extend blade service life greatly |
1. Blade edge wears quickly and needs frequent replacement
Cause: Mismatched ordinary coating cannot resist long-term friction and impurity scouring.
Solution: Adopt heavy-duty reinforced ceramic coating to improve overall wear resistance.
2. Blade corrodes and becomes blunt in humid & acidic pulp environment
Cause: The coating lacks anti-corrosion performance.
Solution: Customize high-density anti-corrosion ceramic coating for wet-end working conditions.
3. Paper surface is scratched or appears streaks
Cause: Coating surface roughness is too high or edge precision is insufficient.
Solution: Use high-precision polished ceramic coating to ensure ultra-smooth contact surface.
4. Blade fails and deforms under continuous high temperature
Cause: Ordinary material cannot withstand long-term thermal load.
Solution: Equip with high-temperature resistant ceramic coating to maintain stable physical properties.
5. Poor scraping effect with residual pulp and sticky dirt
Cause: Unmatched coating friction and flatness cannot adapt to machine speed.
Solution: Customize coating formula and surface finish according to on-site machine parameters.
