Offer metal powder coating, wear-resistant metal spraying, and wear-resistant metal coatings.

We can restore scrapped and out-of-tolerance mechanical parts, bringing them “back to life.” Additionally, we can pre-protect the surfaces of new workpieces with wear-resistant and corrosion-proof coatings, effectively “extending their lifespan.”

Tungsten carbide wear-resistant coating applied to the rotors and sealing devices of internal mixers.

Guangzhou Sanxin utilizes the advanced, U.S.-imported PRAXAIR JP8000 supersonic spraying equipment to apply wear- and corrosion-resistant coatings to tungsten carbide spray-mixed rotor blades, mixing chambers, and sealing devices of internal mixers.

The manufacturer provides on-site construction services for nano-ceramic coatings and plasma cladding in the lithium-ion new energy industry.

On-site Plasma Coating Spray Application Procedure 1. Site cleanup, enclosure of the construction area, and connection of power and gas to the construction equipment; 2. Surface sandblasting treatment of the substrate to meet or exceed the national standard of Sa2.5 or higher; 3. On-site plasma cladding spray application; 4. Quality inspection: use a compositional analyzer to check the material composition and content of metallic impurities; perform hardness and thickness measurements of the coating; and carry out acceptance testing upon completion of the work.

Undertaking on-site construction of lithium-ion battery industry equipment, plasma cladding coatings, and nano-ceramic coatings.

Guangzhou Sanxin Company utilizes American Miller plasma cladding equipment and technology to perform on-site cladding of nano-ceramic coatings, which are suitable for hopper, screw, and ribbon mixing and conveying systems in the lithium-ion new energy industry.

HVOF Supersonic Flame Process: In supersonic flame spraying, oxygen and aviation kerosene are mixed in a premixing system and then burned in a high-pressure combustion chamber. The resulting flame jet, combined with high-pressure air passing through a Laval nozzle, generates a high-temperature, high-velocity flame stream that heats metal-ceramic powders to a semi-molten state.

Tungsten Carbide Wear-Resistant Coating for Spiral Shafts

Wear-resistant coating for feeding tubes in lithium-ion battery equipment

1. Currently widely used in the lithium-battery slurry industry, this coating is suitable for various types of lithium-battery equipment, including dispersion disks, screw shafts and spiral mixers, wear-resistant components for pulverizers, tanks, cylindrical bodies, conical hoppers, powder-handling machines, feeding systems, electrode manufacturing equipment, and wear-resistant coatings. 2. The tungsten carbide coating achieves a hardness of HRC75 or higher—second only to diamond among ultra-hard, wear-resistant coatings—effectively preventing metal ions from entering the powder and thus avoiding metal contamination of the powder caused by material wear. 3. Guangzhou Sanxin utilizes American Plasmax supersonic spraying equipment and imports tungsten carbide materials. This tungsten carbide coating is particularly well-suited for applications involving particle abrasion. 4. During coating application, the workpiece temperature does not exceed 150 degrees Celsius, ensuring no deformation occurs in the workpiece. 5. The coating has a surface roughness of R3.2 or lower, with a controllable coating thickness ranging from 0.10 to 0.35 mm. After pore-sealing treatment, the coating does not react with NMP. 6. Depending on the specific service environment, you can choose between wear-resistant and corrosion-resistant coatings.

Tungsten carbide wear-resistant coating applied by dispersion disk spraying

Lithium equipment-specific isolation layer, tungsten carbide wear-resistant coating sprayed onto the dispersion disc surface—tungsten carbide wear-resistant.

Wear-resistant coating for electrode roller

Tungsten Carbide Coating for Electrode Rollers: The typical manufacturing process for lithium-ion battery electrodes involves mixing active materials, binders, and conductive agents to form a slurry, which is then coated onto both sides of copper or aluminum current collectors. After drying, the solvent is removed, resulting in electrode sheets. The particle coating on these electrode sheets is subsequently compacted and densified through rolling, followed by cutting or slitting into individual strips. Rolling is the most commonly used compaction technique for lithium-battery electrodes. Compared to other compaction methods, rolling significantly alters the pore structure of the electrode sheets and also affects the distribution of conductive agents, thereby influencing the electrochemical performance of the battery. To achieve an optimized pore structure, it is crucial to have a thorough understanding of the rolling compaction process. Figure 1 illustrates the basic process of electrode rolling. Materials—Equipment—Processes—Solutions: We have accumulated extensive experience in coating applications and are currently replicating these successful cases. We will guide you through the entire coating-manufacturing transition process, ensuring: rapid production start-up; a reliable supply solution covering materials, equipment, and processes all in one package; coating trials conducted either at your site or at our technology center; and consistently high coating quality and efficiency.
