Shanghai Duomu has been a leading manufacturer and exporter of PTA (Plasma Transferred Arc) cladding machines and Laser cladding machines for more than ten years. With a robust technical background, we don't just sell equipment; we provide the metallurgical science required to extend the lifespan of mission-critical components.
In modern industrial manufacturing, the cost of equipment is often eclipsed by the cost of downtime. Our mission is to eliminate that vulnerability through "Surface Engineering." Whether it is a choke valve in an oil field or a turbine blade in a power plant, our cladding technologies provide a wear-resistant, corrosion-resistant, and high-temperature-stable layer that restores and enhances performance.
Our independent R&D team is the engine of our innovation. We specialize in the development and sale of high-efficiency Plasma Powder Surfacing Machine DML-V03CD and Integrated Multifunctional Plasma Powder Welding systems. Our focus is on two primary pillars:
We provide complete sets of industrial equipment solutions, from robotic automation to custom internal hole welding torches for complex geometries.

Our technologies are deployed in the world's most demanding environments, ensuring operational continuity where failure is not an option.
Restoring turbine blades and engine mounts with ultra-low HAZ laser hardening.
Hardfacing plowshares and cutters to resist abrasive soil wear.
Cladding valve seats and drill stabilizers for extreme corrosion resistance.
High-deposition PTA surfacing for rolls and continuous casting equipment.
Located in the heart of Shanghai’s industrial hub, Duomu leverages a comprehensive ecosystem of component suppliers. This allows us to move from custom design to factory testing within weeks, not months.
By integrating R&D, manufacturing, and global logistics under one roof, we reduce overhead costs, passing significant savings to our international partners while maintaining CE and ISO standards.
Our proximity to the Port of Shanghai ensures rapid shipping to Southeast Asia, Europe, and the Americas. We offer 24-hour remote diagnostic support and localized technicians for large-scale installations.
As we move toward Industry 4.0, Shanghai Duomu is pioneering the integration of AI-driven defect detection within our cladding systems. Our roadmap includes:
"In Oil & Gas, the Real Cost Is Downtime—Not the Component. Duomu’s valve cladding system reduced our maintenance cycles by 40%."
"The dilution rate in PTA hardfacing is critical. Duomu’s DML-V03CD provides the most stable arc we've seen in the metallurgy sector."
"Efficiency is not just about speed; it's about reliability. Their 24-hour support team was vital during our facility upgrade."
A: PTA (Plasma Transferred Arc) offers a higher deposition rate and is generally more cost-effective for thick coatings on large parts. Laser Cladding provides lower heat input, which results in a smaller heat-affected zone and lower dilution, making it superior for precision components.
A: Yes, we specialize in customized equipment, including hydraulic rod cladding machines, ball valve welders, and deep-hole torches designed for internal diameters.
A: We utilize a rigorous multi-stage testing process, including metallurgical analysis of sample clads and long-term stress testing of the robotic components before shipping.
A: We provide global remote support 24/7. For large projects, we can dispatch engineers for on-site commissioning and staff training to ensure high-quality output.
