Explore our flagship industrial-grade plasma cladding, laser deposition, and automated surfacing solutions engineered for high-demand manufacturing and repair operations.
Modern industrial components operate in extremely aggressive environments. Components used in oil and gas, heavy mining, petrochemical extraction, and aerospace face severe degradation from combined sliding abrasion, impact, temperature cycling, and chemical corrosion. Standard thermal spraying or basic arc welding techniques often fall short, resulting in high dilution, thermal distortion, or weak mechanical bonds that delaminate under stress.
An Integrated Plasma System provides a highly controlled, high-energy density solution. By utilizing a Plasma Transferred Arc (PTA) or combining it with precision laser cladding modules, these systems melt both the substrate surface and the alloy powder feed simultaneously. This creates a dense, defect-free, metallurgical bond characterized by extremely low dilution rates (typically under 5%) and a minimal heat-affected zone (HAZ).
For more than ten years, Shanghai Duomu has stood at the forefront of this technological curve. As a premier manufacturer and exporter, we design, develop, and build state-of-the-art PTA cladding and laser deposition machines that deliver long-term wear resistance, reducing component lifecycle costs and preventing unplanned manufacturing downtime.
Our in-house, dedicated R&D engineering team builds, programs, and validates our plasma and laser cladding hardware. Unlike simple assemblers, Shanghai Duomu controls the entire intellectual property chain. This includes the design of specialized plasma surfacing torches, custom high-precision powder feeders, and advanced robotic pathing software.
We supply complete industrial equipment solutions engineered to support complex, large-scale remanufacturing projects. From restoring heavy hydraulic cylinders to hardfacing critical mining picks, our systems achieve the high thermal stability needed to support continuous 24/7 manufacturing cycles. By combining precise PLC automation with high-efficiency cooling, we ensure that every square millimeter of cladding meets strict quality and density standards.

How Shanghai Duomu leverages its geographic and industrial positioning to deliver world-class thermal surfacing technology globally.
From manufacturing the core plasma torch to programming the control software, our vertical integration reduces component margins and guarantees spare parts availability. Clients bypass intermediaries, receiving direct factory technical support.
We leverage proximity to high-purity metallurgical powder producers. This allows us to offer specialized hardfacing materials—including Cobalt-based (Stellite equivalents), Nickel-based, and Tungsten Carbide (WC) blends—at highly competitive prices.
Every system undergoes a rigorous 72-hour continuous cycle test prior to dispatch. We verify optical alignments, test power supplies, and confirm gas flow repeatability to ensure reliable operation upon installation.
Our systems are deployed globally to safeguard machinery operating in severe conditions across these key sectors:
