In the modern industrial landscape, the durability and reliability of mechanical components are paramount. Shanghai Duomu has emerged as a premier manufacturer and exporter, specializing in Equipo Para Soldadura Por Plasma (Plasma Welding Equipment) and Laser Cladding systems for over a decade. Our technical foundation is built upon the synthesis of metallurgical expertise and advanced automation.
Our Plasma Transferred Arc (PTA) cladding machines are designed to provide a superior metallurgical bond with the base material, ensuring high wear resistance, corrosion protection, and thermal stability. By providing significant "Information Gain" in the field of surface modification, we help global enterprises transition from simple maintenance to strategic asset life-cycle management.

China's industrial ecosystem allows us to source high-grade electronic components and metallurgical powders with unprecedented speed, reducing lead times for custom equipment from months to weeks.
We leverage localized R&D to provide high-end Laser and Plasma cladding solutions at a price point that offers significant ROI for global SMEs without compromising on "E-E-A-T" principles.
From hydraulic rod cladding to specific valve surfacing, Chinese factories excel in rapid prototyping and tailor-made mechanical design for unique industrial challenges.
Our independent R&D team focuses on the critical dilution rate. In PTA hardfacing, achieving a low dilution rate while maintaining a strong metallurgical bond is the hallmark of quality. Our DML series machines maintain stable arc performance during long-term operation, ensuring that the chemistry of the deposited alloy remains uncontaminated by the substrate.
The technical department at Shanghai Duomu provides complete industrial solutions, including:
Penetrating critical sectors with precision and reliability.
Mining & Coal: Hardfacing of shearer picks and screw conveyors to combat extreme abrasion.
Nuclear Power: Precision cladding of valve seats and seals where failure is not an option.
Green Energy: Repairing biomass energy processing components to extend service life and reduce waste.
The global welding industry is moving away from "discard and replace" towards "remanufacturing." Procurement needs are shifting toward equipment that can restore expensive shafts, blades, and valves to their original (or better) condition. Our Laser Cladding robots are at the forefront of this trend, offering minimal heat-affected zones (HAZ) and superior surface finishes.
International buyers now prioritize integrated multifunctional systems. We address this by offering machines like the DML-V03BD, which integrates powder welding and surfacing into a single, high-efficiency unit. We understand the localized application scenariosโfrom the humid oil fields of the Middle East to the high-altitude mines of South America.
PTA (Plasma Transferred Arc) uses a plasma arc to melt powder and a thin layer of the substrate, offering higher deposition rates. Laser Cladding uses a laser beam, resulting in a smaller heat-affected zone and lower dilution, ideal for high-precision components.
We adhere to strict quality control protocols, utilizing 10+ years of manufacturing experience. Each machine undergoes rigorous testing in real-world simulation environments before export.
Yes, we specialize in custom solutions for hydraulic rods, ball valves, screw conveyors, and turbine blades. Our gantry and robotic systems can be scaled to the component size.
By extending the life of high-wear parts by 3x to 10x, most industrial clients see a full return on investment within 6-12 months through reduced downtime and replacement costs.
"One of the most critical factors that directly affects overlay performance is the dilution rate. Shanghai Duomu machines have perfected this balance."
"In Oil & Gas, the real cost is downtime. Their cladding solutions for mud pump valve seats have saved our operations millions."
"Improving PTA hardfacing efficiency is about depositing more alloy in less time without losing quality. Their DML series delivers."
