High-wear-resistant ultra-smooth roller

High-wear-resistant, ultra-smooth-surface rollers—our company uses the Plasmax JP8000 equipment from the U.S. to apply tungsten carbide coatings with the following performance parameters: Hardness: above HV1300 (HVAF); Porosity: less than 0.5% (HVAF); Bonding strength: over 80 MPa (HVAF). If your products demand extremely high surface finish and dimensional accuracy, or if they will be in long-term contact with liquids and thus require enhanced wear resistance and corrosion protection, you should choose our tungsten carbide coatings applied using the U.S.-made Plasmax JP8000 equipment. Materials—Equipment—Processes—Solutions: We have accumulated extensive experience in coating applications and are now successfully replicating these proven case studies. We’ll guide you through the entire coating manufacturing transition process, ensuring: rapid production start-up; a reliable, one-stop supply solution covering materials, equipment, and processes; coating trials conducted either on-site at your facility or at our technical center; and consistently high coating quality and efficiency.

The most important feature of insulated bearings is the presence of a very thin coating (on the micrometer level) on their surface, which provides electrical insulation and can withstand electrical arcing caused by voltages exceeding 500V. A thicker coating can even resist high-voltage discharges up to 1,000V. As a result, these bearings effectively prevent defects such as arcing induced by induced currents on the spindle and bearing, which could otherwise lead to corrosion on the bearing surface, the formation of shrinkage cavities on metal surfaces, and the creation of grooves on the bearing’s rolling elements.

A fully automatic pick-and-place machine is a device used to automatically mount components at high speed and with high precision. It is the most critical and sophisticated piece of equipment in the entire SMT production process. As the primary equipment in an SMT production line, pick-and-place machines have evolved from early low-speed mechanical models to high-speed optical alignment machines, and are now moving toward multifunctional, flexible, and modular designs.

Wear and corrosion-resistant thermal spray coating repair for components in the iron and steel industry, including submerged rolls, guide rolls, furnace bottom rolls, and conveyor rolls.

In the iron and steel industry, numerous equipment components operate continuously at full load under harsh conditions characterized by high temperatures, oxidation, high-temperature corrosion, mechanical wear, and corrosion by molten metals. As a result, these components are highly susceptible to damage—for example, the high-temperature corrosion of converter shrouds and flues; thermal and mechanical fatigue of support rollers, guide rollers, and pinch rollers in continuous casting production lines; mechanical wear of mold plates, conveying rollers, and various process rollers in slab continuous casting lines; fatigue and wear of tension rollers and straightening rollers in cold-rolling mill production lines; high-temperature corrosion and scaling on bottom rollers in continuous annealing furnaces; and erosion and wear caused by molten metal on immersion rollers, tension rollers, and guide rollers in continuous hot-dip galvanizing lines. All these failure issues can be effectively addressed by using thermal spraying techniques to apply high-strength, high-performance materials.
