High-performance solutions for additive manufacturing and surface hardening.
Shanghai Duomu: Over a decade of pioneering technical excellence.
Shanghai Duomu has established itself as a global authority, serving as a leading manufacturer and exporter of PTA cladding machines and Laser cladding systems for more than ten years. Our foundation is built upon a robust technical background and an unwavering commitment to R&D.
Our independent R&D team doesn't just assemble machines; we engineer solutions. By developing, producing, and selling proprietary plasma cladding equipment, we ensure that every unit offers stable performance and maintains efficient long-term operation under the most demanding industrial environments.
From traditional surfacing to AI-integrated additive manufacturing.
Transitioning from manual arc welding to digitally controlled Plasma Transferred Arc (PTA) systems. Focus on reducing dilution rates (below 5%) and enhancing metallurgical bonding.
The rise of 6-axis robotic arms for complex geometries. Our laser hardening robots provide localized heat treatment with surgical precision, minimizing thermal distortion.
Real-time monitoring and adaptive control loops. Future PTA machines will utilize AI to adjust powder feed rates and travel speeds dynamically based on melt pool sensor feedback.
Our products have penetrated the most critical sectors of the global economy.
Enhancing wear resistance for tillers and harvesters, extending component life by 300% in abrasive soil environments.
Precision cladding of turbine blades and high-temperature alloy components with minimal heat-affected zones.
Corrosion-resistant overlays for drill stabilizers and valves, crucial for deep-sea and high-pressure oil extraction.
Restoring heavy-duty rolls and dies, providing a sustainable alternative to complete part replacement through remanufacturing.
In the era of "Global Localization," Shanghai Duomu represents the pinnacle of Chinese manufacturing efficiency. Our "Factory 4.0" approach ensures that we are more than just a supplier; we are a strategic partner in your supply chain.
We understand the complexities of global trade. Our equipment meets international safety and quality standards, including CE certification and ISO protocols.
Our support doesn't end at shipping. We provide:
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 today are shifting from "Replace" to "Remanufacture," and PTA machines are at the heart of this revolution.
In Oil & Gas, the real cost is downtime—not the component. When a choke valve fails due to sand erosion or a mud pump valve seat wears beyond tolerance, waiting for a new part can cost millions in lost production. Our multifunctional plasma powder welding machines allow for the rapid application of tungsten carbide or stellite overlays, returning parts to service with better-than-new performance characteristics.
Plasma Transferred Arc (PTA) hardfacing offers a unique balance between the high speed of MIG/MAG and the high precision of Laser Cladding. It provides a fully metallurgical bond with the substrate, which is essential for heavy-load applications where mechanical bonding (like thermal spray) might flake or peel. Furthermore, PTA allows for a wide range of powder alloys, many of which are too brittle or difficult to form into wire for traditional welding.
Precision tools for the modern industrial age.
