Industrial-grade equipment engineered for extreme durability and metallurgical excellence.
In the modern industrial landscape, wear and corrosion are the primary enemies of operational uptime. Plasma Transferred Arc (PTA) technology has emerged as the gold standard for high-performance alloy deposition. Unlike traditional MIG/TIG welding, PTA offers a high-energy density plasma arc that ensures a metallurgical bond with extremely low dilution (typically 5-10%). This allows the base material to retain its structural integrity while the overlay provides superior hardness (up to 70 HRC).
Shanghai Duomu, with over 10 years of specialized manufacturing experience, has pioneered the integration of AI-driven control systems into PTA equipment. This "Information Gain" in our technical roadmap ensures that every pulse of the arc is monitored, providing a level of precision previously only seen in laser cladding, but at a fraction of the operational cost.
The global shift toward deeper oil & gas exploration and renewable energy (wind power bearings) has increased the demand for hardfacing that can withstand corrosive salt environments and abrasive silts.
The integration of IoT and cloud monitoring allows factories to track the lifecycle of a PTA-cladded valve or hydraulic rod from its first deposition to its 10th year of service.
Strict environmental regulations in the EU and North America are pushing industries away from hexavalent chromium plating toward PTA and Laser Cladding as greener, more durable alternatives.
Customization cycles that take 6 months in Europe are completed in 45 days here.
Our independent technical department focuses on high-integration systems like the DML-V03CD.
30-50% better ROI compared to legacy Western systems without sacrificing quality.
Direct export from Shanghai port ensures global delivery within weeks, not months.

Technical Support
From the depths of the earth to the vacuum of space, our cladding solutions protect vital components.
Hardfacing plowshares and harvester blades to extend service life by 300% in abrasive soils.
Precision cladding for turbine blade tips and missile components using specialized superalloys.
Protecting drill stabilizers and mud pump valves from extreme erosion and high-pressure corrosive fluids.
Hardfacing continuous casting rolls to resist thermal fatigue and mechanical wear at 1000°C+.
Our technical department provides more than machines; we provide "Surface Engineering Strategies." From material selection to post-weld heat treatment, we ensure your project succeeds.
Overcoming Dilution Rates: Achieving high-quality overlays is about selecting the right alloy powder. In PTA hardfacing, we focus on managing the heat input to maintain metallurgical purity.
Efficiency Beyond Speed: Industrial production efficiency isn't just about deposition rate; it's about the reliability of the system during 24/7 operation cycles.
Oil & Gas Downtime: The real cost of a failed choke valve is the $100k/day downtime, not the component itself. PTA cladding is the ultimate insurance policy.
Standard systems are shipped within 30 days. Fully customized robotic cells with integrated laser hardening typically require 60-90 days for engineering and testing.
We provide 24/7 remote technical support. For critical installations, our engineers provide on-site commissioning and staff training globally.
We specialize in Stellite (Cobalt-based), Colmonoy (Nickel-based), Tungsten Carbides, and various stainless steel alloys for specialized corrosion resistance.
Yes, all our exported machinery meets CE certification and adheres to ISO 9001 quality management protocols.
