Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machines and Laser cladding machines for more than ten years, backed by a strong technical team and a rigorous engineering culture. Our mission is to deliver precision surface engineering solutions that extend component life, reduce downtime, and maximize return on investment for industrial clients worldwide.
Founded on the principle that surface performance is the foundation of mechanical reliability, we combine metallurgical expertise with automation engineering to produce equipment trusted by clients in over 30 countries. Every machine we build is tested under real industrial conditions before delivery.
Our numbers reflect a decade of relentless commitment to quality, precision engineering, and customer success across critical industries.
At present, the company's products have penetrated into many fields such as aerospace military industry, nuclear power, petrochemical industry, coal mines, metallurgy and forging, agriculture, water conservancy and electric power, delivering measurable performance improvements across every sector.
We maintain an independent R&D team that develops, produces, and continuously refines plasma cladding machine equipment in-house. Our welding machines deliver stable, consistent performance engineered for efficient long-term industrial operation, minimising unplanned downtime and reducing total cost of ownership.
In addition, the laser cladding equipment sold by the company can effectively support large-scale remanufacturing projects. We have mature technological means to provide complete sets of industrial equipment solutions — from feasibility study and process design through to on-site commissioning and after-sales technical support.
From precision engineering to global support, Shanghai Duomu delivers end-to-end cladding solutions that set the benchmark in surface protection technology.
Our factory controls every stage of production — from raw material selection and precision machining to final assembly and quality inspection — ensuring consistent output and rapid lead times.
We develop our own plasma transferred arc and laser cladding processes, giving clients access to cutting-edge surface engineering techniques not available from standard equipment suppliers.
We design and manufacture bespoke equipment — including hydraulic rod cladding machines, pick cladding machines, valve cladding machines, and intelligent robot cladding systems — tailored precisely to your production requirements.
Having shipped to over 30 countries, our logistics and export documentation team ensures smooth international delivery. We understand the compliance and certification requirements across key markets.
Our robotic cladding solutions integrate seamlessly with existing production lines, enabling 24/7 automated hardfacing operations with consistent overlay quality and minimal operator intervention.
From remote diagnostics and spare parts supply to on-site engineering visits, our dedicated support team ensures maximum uptime and long-term equipment performance for every client.
Our laser cladding and PTA hardfacing equipment is the backbone of major remanufacturing operations worldwide. From restoring hydraulic cylinders in mining to extending valve service life in petrochemical plants, Shanghai Duomu's technology delivers measurable cost savings and sustainability benefits.
We can provide customized equipment — automatic laser cladding equipment, automatic plasma cladding equipment, intelligent robot cladding equipment, and special industry-specific machines including hydraulic rod cladding machines, pick cladding machines, and valve cladding machines — all engineered to your exact specifications.
Our engineers regularly publish technical insights covering PTA hardfacing best practices, dilution rate control, and application-specific cladding solutions — demonstrating our depth of expertise across critical industries.
The PTA Welding Valve Application Guide is not just a process choice for valve manufacturers facing high wear, high corrosion, and high-temperature erosion working conditions, but also a key path to improving product competitiveness. As industries such as petrochemical evolve, the demand for precision hardfacing grows significantly.
Valve & Petrochemical
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 — making hardfacing a critical investment.
Mining & Bulk Handling
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 — a parameter our engineers have spent years mastering.
PTA Process Engineering
In industries such as Oil & Gas, Mining, Power Generation, Cement, and Heavy Equipment Manufacturing, hardfacing is no longer just a repair process. It has become a critical technology directly related to equipment lifespan, downtime costs, maintenance frequency, and total operational expenditure.
Heavy Industry & Mining
In industries such as oil & gas, petrochemical, power generation, mining, and marine engineering, industrial valves are constantly exposed to severe operating conditions including high pressure, extreme temperatures, corrosive media, abrasive wear, and sand erosion — demanding the most advanced cladding solutions available.
