Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machines and Laser cladding machines for more than ten years. With a strong technical background and an independent R&D team, we develop, produce, and sell high-performance equipment that serves as the backbone for Custom PTA Screw production worldwide.
Our systems are designed for stability, maintaining efficient long-term operation even in the most demanding industrial environments. By leveraging Plasma Transferred Arc (PTA) technology, we provide metallurgical bonding that far exceeds the performance of traditional thermal spraying or standard welding.
Years of Industry Leadership
Global Projects Completed
Custom Solution Capability
Unlike off-the-shelf components, our PTA screws are engineered for specific wear profiles, using bespoke alloy powders like Tungsten Carbide or Stellite.
We optimize dilution rates to ensure the protective layer maintains maximum hardness while ensuring a perfect metallurgical bond with the base screw material.
Located in Shanghai's industrial hub, we integrate raw material sourcing, R&D, and precision machining to reduce lead times by up to 40% compared to Western competitors.
The industry is moving toward Smart Remanufacturing. High-value components like injection molding screws and conveyor screws are no longer discarded when worn. Instead, Automated PTA Cladding allows for the restoration of these parts to "better-than-new" condition. Current trends include the integration of AI-driven sensors to monitor weld pool stability and the use of robotic arms for complex screw geometries.
Our products have penetrated into critical sectors requiring extreme durability and precision.
Protecting soil-engaging tools and feed screws from abrasive wear.
High-precision cladding for engine components and structural parts.
Anti-corrosion and wear-resistant overlays for drill stabilizers and pump valves.
Restoring heavy-duty rollers and forging dies subjected to thermal fatigue.
For global enterprises, the challenge isn't just buying a screw; it's maintaining a production line. Shanghai Duomu provides complete industrial equipment solutions. Our intelligent robot cladding systems can be integrated into existing factory floors, allowing for in-house repair of Hydraulic rods, Pick cladding, and Valve seats.
Our Laser Hardening Robots and Automatic Plasma Cladding systems (like the DYY-LC501) offer a level of repeatability that manual welding simply cannot match. This is crucial for industries like Nuclear Power and Water Conservancy, where safety and reliability are non-negotiable.
While nitrocarburizing provides a thin hard shell, PTA cladding applies a thick layer of wear-resistant alloy (up to 5mm+). This provides a metallurgical bond that won't flake off under high torque or abrasive loads, extending service life by 300-500%.
We utilize independent R&D testing for every batch. Our equipment provides digital logging of welding parameters, ensuring that the dilution rate and hardness HRC levels meet the specific requirements of the client's application.
Yes. Our laser cladding equipment is specifically engineered to support large-scale industrial remanufacturing projects, capable of handling components weighing several tons with high precision.
Most clients in the mining or chemical processing sectors see a return on investment within 6-12 months due to drastically reduced downtime and fewer replacement part purchases.
