Product Overview
Our factory provides a full range of customized paper making rollers, covering press roller, calender roller, guide roller, vacuum transfer roller, coating roller, wrinkle roller and all roller accessories for papermaking machines. Adopting high-strength seamless steel pipe and precision casting base body, matched with industry-leading ceramic coating and tungsten carbide coating technology, our rollers completely surpass ordinary rubber rollers and common sprayed rollers on the market in terms of wear resistance, high-temperature resistance, anti-corrosion and anti-stick performance. All products comply with international industrial standards and export inspection norms, widely exported to Europe, Southeast Asia, Middle East, Africa and other global regions. We support exclusive coating customization and personalized parameter adjustment according to paper types and production working conditions, providing global paper mills with high-efficiency, low-consumption and long-life roller overall solutions.
Why Our Paper Making Rollers Outperform Ordinary Market Rollers
Most ordinary paper rollers on the market adopt ordinary rubber surface, common paint spraying or ordinary alloy coating, which are prone to wear, aging, peeling, corrosion and deformation in long-term high-speed and high-load operation, resulting in frequent replacement, unstable paper quality and increased production costs. Our company upgrades the core technology in base material, surface coating and production technology, with comprehensive performance far exceeding industry standard products:
1. Premium Base Material & Precision Integrated Craftsmanship
We adopt high-rigidity seamless steel pipe and high-density cast iron base body, through integral forging, secondary stress relief and ultra-precision dynamic balance calibration. The roller body has uniform wall thickness, no deformation, no swing during high-speed operation, and runs stably for 24 hours. Compared with ordinary welded rollers, it has higher structural strength, stronger pressure resistance and longer structural service life, effectively avoiding paper deviation and paper breakage caused by roller shaking.
2. Top-grade Functional Coating, Far Beyond Ordinary Surface Treatment
Ordinary market rollers only rely on simple rubber wrapping or ordinary anti-rust spraying, with low hardness, poor wear resistance and easy aging failure. Our core advantage lies in customized high-performance ceramic coating and tungsten carbide coating processed by advanced supersonic flame spraying technology. The coating is densely combined with the roller base, featuring ultra-high hardness, zero peeling, anti-stick, anti-corrosion and high-temperature resistance. It solves multiple industry pain points of traditional rollers such as easy wear, sticky pulp, rusting and poor heat resistance, greatly reducing equipment downtime and maintenance costs.
3. Scene-based Custom Matching, No Wasted Performance
We abandon the one-size-fits-all single coating mode of ordinary manufacturers. According to different paper machine sections, operating speed, paper types and working environment, we selectively match ceramic coating and tungsten carbide coating, realizing accurate adaptation of product performance and working conditions. It not only ensures extreme production performance, but also controls customer procurement costs, with higher cost performance than ordinary universal rollers.
4. Strict Export-level Quality Control
All rollers undergo strict dynamic balance test, surface flatness test, coating adhesion test and pressure resistance test. Each product is equipped with complete inspection reports and certification documents, meeting global paper mill safety production standards and supporting smooth customs clearance and factory acceptance of overseas customers.
Core Performance Advantages of Custom Coatings
Our two core functional coatings have exclusive superior performance, both far exceeding ordinary rubber, plastic and common alloy coatings on the market, covering all high-standard working condition needs of papermaking production:
1. Tungsten Carbide Coating (High-end Industrial Grade)
Adopting imported tungsten carbide alloy powder and 5 Mach supersonic flame spraying process, the coating has ultra-high density and strong bonding force (bonding strength >700kg), porosity less than 1%, never peeling or falling off. It is the highest-standard surface treatment technology for paper making rollers at present.
Ultra-high Hardness & Wear Resistance: Hardness up to HRC70+, close to diamond level, resisting long-term friction of doctor blades, paper fibers and mineral fillers. The service life is 8-10 times that of ordinary rubber rollers and 3-5 times that of ordinary sprayed rollers.
Extreme Corrosion & High-temperature Resistance: Resist acid, alkali, salt and chemical sizing agent corrosion, stably adapt to 1400℃ high-temperature environment, no aging, no cracking in high-temperature drying and humid workshop conditions.
Super Smooth & Anti-fouling: The surface can be polished to mirror level (Ra≤0.1μm), with ultra-low surface tension, effectively preventing pulp residue, adhesive and fiber adhesion, avoiding sticky roller and paper breakage.
Stable High-speed Operation: Super wear resistance ensures no surface deformation or scratches during long-term high-speed operation of paper machines, keeping paper thickness uniform and improving finished product yield.
2. High-performance Ceramic Coating (Cost-effective Universal Grade)
Independently optimized ceramic composite coating, with balanced performance and high cost performance, perfectly replacing ordinary anti-wear coatings, suitable for most conventional papermaking working conditions, and is the preferred upgraded coating for medium and low-load paper machines.
Excellent Anti-wear & Anti-slip Performance: Moderate hardness and uniform surface texture, which can increase paper web friction, prevent paper sliding and deviation, and ensure stable paper feeding.
Strong Anti-stick & Anti-oxidation: Compact coating structure isolates air and moisture, effectively preventing roller surface rust and oxidation, reducing manual cleaning frequency.
Good Thermal Stability: Low thermal expansion coefficient, no deformation in high-temperature working environment, stable heat conduction performance, matching conventional drying and pressing processes.
Economical & Durable: Lower procurement cost than tungsten carbide coating, far longer service life than ordinary rollers, suitable for mass continuous production and cost control projects.
Coating Selection & Precise Working Condition Matching
We provide targeted coating matching solutions for different types of paper rollers and production scenarios, realizing customized adaptation of one roller for one working condition:
Tungsten Carbide Coating Application Scenarios (High-standard Working Conditions)
High-speed Paper Machine Rollers: Suitable for high-speed calender rollers, press rollers and coating rollers, adapting to ultra-high-speed continuous operation, resisting long-term blade friction and filler wear.
Recycled Paper & Chemical Additive Paper Production: Resist chemical corrosion of various additives in recycled pulp, prevent roller surface pitting and damage, and extend equipment life.
High-precision Paper Production: Suitable for high-end cultural paper, coated paper, photographic paper and food packaging paper, ensuring ultra-smooth roller surface and high flatness finished paper.
Vacuum Transfer Roller & Special Industrial Rollers: Adapt to high-load and high-humidity extreme working environments, solve the problem of easy wear and blockage of porous rollers.
Ceramic Coating Application Scenarios (Conventional Upgraded Working Conditions)
Conventional Press Rollers & Guide Rollers: Suitable for kraft paper, corrugated paper, tissue paper and ordinary packaging paper production, stable paper feeding and anti-deviation.
Medium & Low-speed Paper Machine Transformation: Replace ordinary rubber rollers and painted rollers, improve wear resistance, reduce maintenance frequency, and achieve cost-effective upgrading.
Humid Conventional Workshop Environment: Excellent anti-oxidation and anti-rust performance, adapting to daily humid production environment, keeping roller surface clean and stable.
