Highly integrated, multifunctional systems engineered to optimize surface hardness and extend working lifetimes under severe mechanical stress.
The Philippines presents a unique operating environment. Spanning over 7,000 islands, its heavy industries—ranging from nickel mining in Caraga and sugar milling in Negros to maritime shipping in Cebu and power generation in Batangas—face aggressive atmospheric conditions. The combination of high ambient humidity, airborne marine salinity, and abrasive mineral ores causes rapid degradation of critical machine parts.
Traditional thermal spraying or manual hardfacing often fails due to limited bond strength and high dilution rates. This is where Laser Cladding and Plasma Transferred Arc (PTA) cladding step in. These technologies create a true metallurgical bond with minimal dilution (typically < 5%), keeping the cladding alloy’s properties pure and intact while keeping the base metal's heat-affected zone (HAZ) exceptionally small.
By deploying automated laser cladding systems, Philippine heavy enterprises can reclaim worn shafts, valves, and hydraulic cylinders locally, eliminating the long lead times and high shipping costs of importing replacement parts.
Request Local Case StudiesUnlike mechanical bonding in thermal spray methods, laser cladding forms a true metallurgical fusion with the substrate, preventing spalling even under extreme impact forces.
The focused laser beam guarantees high power density, cooling the melt pool rapidly and preventing heat deformation in high-precision engineering components.

For over a decade, Shanghai Duomu has been a pioneering force in the R&D, manufacturing, and global export of high-performance PTA (Plasma Transferred Arc) cladding machines and state-of-the-art Laser Cladding equipment.
Backed by a strong technical background and an independent research and development team, we design systems that deliver unparalleled stability and high duty-cycle operations. Whether you are looking for localized mobile laser systems or automated gantry-style manufacturing lines, we supply the complete engineering ecosystem, including custom torches, powder feeders, and CNC programming tools.
At Shanghai Duomu, we believe that surface engineering is not a one-size-fits-all field. Different alloys (such as Nickel-based, Cobalt-based, Iron-based, or Tungsten Carbides) call for precise thermal input controls. Our dedicated R&D division builds the hardware and designs the path planning software and parameter sets that support complex additive manufacturing.
Our customized machinery portfolios range from automated plasma surfacing setups to intelligent 6-axis robotic arm laser systems. We provide fully integrated systems specifically built for niche requirements, including hydraulic cylinder rod overlays, mining picks, industrial valve sealing faces, and pump sleeves.
| Cladding Parameter | Laser Cladding System | PTA Cladding System |
|---|---|---|
| Dilution Rate | < 2% (Extremely low) | 3% - 5% (Very low) |
| Heat Input & Distortion | Minimal (Microscopic HAZ) | Low to Moderate |
| Coating Thickness (per pass) | 0.5 mm - 2.0 mm | 1.5 mm - 5.0 mm |
| Deposition Rate | 1.0 - 5.0 kg/h | 2.0 - 10.0 kg/h |
Engineered for high duty-cycle manufacturing operations and severe-wear component remanufacturing.
As an industry-leading manufacturer based in Shanghai, we provide our customers in the Philippines with key logistics advantages. The strategic proximity of Shanghai Port to major Philippine shipping corridors (including Manila, Cebu, Davao, and Cagayan de Oro) ensures quick transit times.
Furthermore, our supply chain is designed to offer high efficiency and cost control. While Western-made laser cladding systems carry high premiums and long lead times for spare parts, we leverage a comprehensive local material ecosystem. This allows us to supply complete systems at highly competitive rates without compromising on build quality or component selection (IPG/Raycus laser sources, Siemens PLCs, and SMC pneumatics).
We analyze substrate chemistry, load demands, and wear environments to identify optimal cladding alloys.
Our technicians define laser power, scanning speeds, powder flow rates, and overlap matrices.
We offer detailed operating manuals, video demonstrations, and step-by-step remote setup assistance.

"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."
Chemical & Refining Valve Supplier
"In industries such as mining, cement, power generation, steelmaking, chemical processing, and biomass energy, screw conveyors are often regarded as auxiliary equipment. Hardfacing has proven to be the most effective preventative choice to avoid unplanned downtime."
Mining & Bulk Handling Systems
"Achieving a high-quality overlay is not only about selecting the right alloy powder or optimizing parameters. One of the most critical factors that directly affects performance is dilution control. Shanghai Duomu systems handle dilution exceptionally well."

Answering technical questions from plant managers and maintenance engineers in the Philippines.
Laser cladding uses a highly focused laser beam as the heat source. This offers very high energy density, minimal heat input, and the lowest dilution rate (<2%). PTA (Plasma Transferred Arc) uses a plasma arc, which generates more heat but achieves higher deposition rates. PTA is often the preferred choice for thicker coatings on large, heavy-duty parts.
Corrosion and wear in marine components (like propeller shafts or hydraulic piston rods) are accelerated by saltwater. Laser cladding allows you to apply high-performance alloys—like Inconel 625 or Duplex stainless steels—directly onto low-alloy steels. This creates a highly corrosion-resistant outer layer that won't peel or delaminate.
Yes, our laser cladding and PTA heads are designed to integrate with CNC machines and multi-axis industrial robots (like ABB, KUKA, or Fanuc). This allows you to apply precise coatings to complex 3D parts, including mining picks, valve components, and turbine blades.
We provide comprehensive technical support, including hardware design, powder supply coordination, and process parameter optimization. Our technical team is available to assist you with installation, troubleshooting, and programming via remote video support.
