We design, engineer, and manufacture every machine in-house at our Shanghai facility, eliminating middlemen and ensuring the highest quality at competitive prices directly to global customers.
Every industrial application is unique. We provide fully customized plasma and laser cladding solutions — from hydraulic rod cladding machines to pick cladding and valve cladding equipment built to your exact specifications.
Our intelligent robotic cladding systems enable highly automated, repeatable processing, reducing operator dependency and dramatically improving output consistency and cycle time in high-volume environments.
With over a decade of international export experience, we provide seamless global logistics, installation guidance, and long-term technical support to customers across more than 50 countries.
Beyond individual machines, we deliver complete turnkey equipment solutions — including process engineering, powder selection consultation, parameter optimization, and operator training for rapid deployment.
For inquiries about our products or pricelist, we commit to responding within 24 hours. Our sales and engineering teams work closely to deliver accurate technical proposals without delay.
We provide customized automatic laser cladding equipment, automatic plasma cladding equipment, intelligent robot cladding equipment, and special-purpose industrial cladding systems tailored to your production requirements.
Shanghai Duomu's cladding and surface engineering equipment has penetrated many demanding sectors — delivering measurable wear life extension and cost savings in every application environment.
From nuclear power and coal mining to petrochemical and water conservancy, our advanced surface engineering systems are trusted across the most demanding global industries. Extend component life. Reduce downtime. Maximize ROI.
Every Shanghai Duomu machine passes through a rigorous multi-stage quality control workflow before it reaches our customers. Our commitment to precision begins in the design phase and continues through commissioning and after-sales support.
Detailed 3D CAD/CAM design by certified engineers, with customer-specific parameter customization and feasibility validation before production begins.
CNC-machined structural components, high-grade welding assemblies, and imported key electronic components for reliability in high-duty-cycle operation.
Full burn-in testing under rated load conditions, arc stability validation, powder feeding accuracy checks, and laser power output calibration before shipping.
Export-standard packaging, international freight coordination, on-site installation guidance, operator training, and long-term technical after-sales service.
Our engineering team continuously publishes in-depth technical research, application case studies, and process optimization guides — empowering our customers to get the best performance from their cladding investments.
In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder or optimizing welding parameters. One of the most critical factors that directly affects overlay performance is the dilution rate. Whether you are targeting maximum hardness, optimal metallurgical bonding, or specific wear resistance properties, controlling dilution is the key engineering lever that experienced PTA operators understand.
Improving PTA hardfacing efficiency is not simply about increasing welding speed or depositing more alloy within a shorter time. In industrial production, the real efficiency of a Plasma Transferred Arc (PTA) hardfacing process depends on a holistic optimization of deposition rate, first-pass quality, material utilization, and machine uptime — all of which our equipment is specifically engineered to maximize.
In Oil & Gas, the real cost is downtime — not the component. When a choke valve fails due to sand erosion, a mud pump valve seat wears beyond tolerance, or a drill stabilizer reaches the end of its service life, the traditional response of replacement creates enormous hidden costs. Our PTA and laser cladding solutions enable remanufacturing that restores components to OEM specifications at a fraction of replacement cost.
For industrial equipment operating in abrasive, erosive, corrosive, or high-temperature environments, wear is inevitable. The real challenge is not preventing wear altogether but choosing the most cost-effective maintenance strategy once wear occurs. Many maintenance teams consistently find that PTA hardfacing with Shanghai Duomu equipment provides superior ROI compared to conventional repair or full component replacement.
In industries such as mining, cement, power generation, steelmaking, chemical processing, and biomass energy, screw conveyors are often regarded as auxiliary equipment. However, maintenance data shows that they are among the most frequent causes of unplanned production downtime. Plasma cladding of screw conveyor flights using carbide-based alloy powders extends service intervals from weeks to years, dramatically reducing total cost of ownership.
Shanghai Duomu's cladding solutions are deployed alongside the world's leading industrial partners across aerospace, energy, mining, manufacturing, and heavy engineering sectors.
For inquiries about our products or pricelist, please leave us a message and we will be in touch within 24 hours. Our engineering team is ready to design a cladding solution tailored to your specific production requirements.
