Industrial-grade surfacing solutions for extreme durability and precision.
In the era of Industry 4.0, the demand for sustainable manufacturing and asset life extension has propelled Laserbeschichtung (Laser Cladding) to the forefront of surface engineering. As a leading China Laserbeschichtung manufacturer, Shanghai Duomu has observed a paradigm shift from traditional "break-fix" maintenance to proactive "predictive remanufacturing."
Modern industries such as aerospace, nuclear energy, and petrochemicals are no longer content with high replacement costs. Laser cladding offers a metallurgically bonded coating with minimal dilution and thermal distortion, making it the preferred choice for high-value component repair. Globally, the market is moving toward High-Speed Laser Cladding (EHLA), which allows for deposition rates significantly higher than traditional methods while maintaining superior surface finishes.
Choosing a Chinese factory for laser cladding equipment provides more than just cost-efficiency. Our infrastructure integrates supply chain resilience with rapid R&D cycles. Shanghai Duomu’s facilities utilize intelligent robot cladding systems and automated CNC integration, ensuring that every machine—from hydraulic rod cladding systems to valve surfacing units—meets stringent international standards. We leverage local industrial clusters to source high-purity alloy powders and advanced laser sources, passing the speed and quality advantages directly to our global procurement partners.

At present, the company's products have penetrated into many fields such as aerospace military industry, nuclear power, petrochemical industry, coal mines, metallurgy and forging, agriculture, water conservancy and electric power, etc.
Enhancing wear resistance for soil-engaging tools and harvesting components, significantly extending service life in abrasive environments.
High-precision cladding for turbine blades and structural components where thermal management and metallurgical integrity are non-negotiable.
Protecting drill stabilizers and mud pump valves from extreme corrosion and sand erosion in demanding offshore and onshore environments.
Remanufacturing of heavy-duty rollers and molds, reducing the "Real Cost of Downtime" for steel mills and forging plants.
Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machine and Laser cladding machine for more than ten years with a strong technical background. Our expertise lies in the fusion of advanced electronics with heavy-duty mechanical engineering.
We host an independent R&D team that develops, produces, and sells plasma cladding machine equipment. Our welding machines are engineered for stable performance and can maintain efficient long-term operation. In addition, our laser cladding equipment effectively supports large-scale remanufacturing projects with mature technological means.

| Feature | Laser Cladding (Laserbeschichtung) | PTA Cladding (Plasma Arc) | Traditional Thermal Spray |
|---|---|---|---|
| Bond Quality | Metallurgical (Extremely Strong) | Metallurgical (Strong) | Mechanical (Moderate) |
| Heat Affected Zone | Minimal (Low Distortion) | Moderate | Low to Moderate |
| Dilution Rate | < 5% (Highest Purity) | 5% - 10% | N/A |
| Coating Thickness | 0.5mm - 2mm per pass | 1mm - 5mm per pass | Microns |
One of the most critical factors that directly affects overlay performance is the dilution rate. In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder or optimizing welding parameters. It’s about managing the metallurgical mix between the substrate and the coating. Our DYY-LC501 series is specifically optimized to balance these parameters, ensuring maximum hardness with minimum material waste.
Common concerns addressed by our senior engineering team.
A: Laser cladding provides a corrosion-resistant and wear-resistant layer with far less heat input than traditional welding. This prevents the warping of long hydraulic cylinders, which is critical for maintaining tight tolerances in heavy machinery.
A: Every machine undergoes a 48-hour continuous operation test and a metallurgical cross-section analysis of the cladding layer before shipment. We provide detailed "FAT" (Factory Acceptance Test) reports to our global buyers.
A: Yes. Our powder delivery systems (like the DML-V03CD) are designed with high-precision feeders that can handle everything from cobalt-based Stellite to nickel-based alloys with 60% Tungsten Carbide loading without clogging.
A: While our factory is in Shanghai, we provide 24/7 remote technical support, AR-guided maintenance, and we have a network of regional partners for on-site commissioning and training.
Real-world data on how our cladding solutions perform in the field.
Overcoming Dilution Rates: achieving a high-quality overlay is not only about powder selection but optimizing the arc distance and travel speed.
Maximizing Hardfacing Efficiency: In industrial production, the real efficiency of PTA depends on the duty cycle and powder recovery rates.
Oil & Gas Downtime: When a mud pump valve seat wears beyond tolerance, the cost of downtime outweighs the component cost by 10x.
