Engineered for high dilution control, extreme durability, and maximum efficiency in Swedish industrial applications.
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. With a focus on thermal spray, hardfacing, and metallurgical coating systems, we deliver turn-key engineering setups to clients across Europe and Scandinavia.
Our solutions cater directly to plants and steel fabrication plants looking to extend the lifecycle of wear-prone components such as screw conveyors, hydraulic cylinder rods, extrusion barrels, and high-performance valves.
Custom-tailored metallurgical solutions designed to handle the abrasive environments of Scandinavian heavy industries.
Sweden’s Kiruna and Malmberget mines require heavy-duty excavation buckets, drill stabilizers, and wear plates that can survive severe abrasive rock formations. Our PTA systems deliver carbide-rich deposits that drastically reduce downtime.
Corrosive chemical processing and aggressive wood fiber feedstocks wear out screw conveyors and chemical valves. Our automated PTA and laser cladding solutions deposit corrosion-resistant nickel and cobalt alloys to prolong operational cycles.
Sweden's SSAB steel mills and numerous Vattenfall hydropower dams run under continuous stress. We supply specialized cladding systems to build up turbine blades and continuous caster rolls, preventing erosion and cavitation.
In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder or optimizing welding parameters. One of the most critical factors that directly affects overlay performance is the dilution rate. The dilution rate determines how much of the base metal melts and mixes with the deposited alloy powder. For Swedish manufacturers processing tough steel alloys, keeping dilution below 5% is vital to preserving the mechanical properties of cobalt (Stellite) or tungsten carbide overlays.
Too much dilution weakens the protective barrier, leading to premature fatigue and wear. Our DM-PT4000 series implements precise closed-loop digital current control, maintaining an exceptionally stable arc that optimizes the thermal field and ensures maximum metallurgical bonding with minimal base-metal penetration.
Deploying advanced automation controls to meet Sweden’s strict efficiency and safety standards.
Our solutions have penetrated critical global industries, delivering maximum uptime and components endurance.
We boast an independent in-house R&D department consisting of veteran metallurgical engineers and automation specialists who design and produce customized plasma cladding machines. Our PTA equipment provides unmatched stability, allowing continuous 24/7 duty cycles on manufacturing lines.
Additionally, our high-power laser cladding machinery can support large-scale component remanufacturing programs. By incorporating advanced CNC systems and robotic arms, we deliver turnkey manufacturing systems capable of precise deposition on complex geometries like screw flights, impellers, and hydraulic valve housings.
Whether you require standard equipment configuration or customized automated cladding systems for Swedish production facilities, we provide comprehensive industrial support.
Innovative designs optimized for specific machine components requiring robust protection from wear, impact, and oxidation.
Compact, high-integration powder feed cladding machine designed for localized alloy deposition and repair.
Advanced multitasking station supporting multiple torch configurations for internal bores and outer structures.

"In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails due to sand erosion, a mud pump valve seat wears beyond tolerance, or a drill stabilizer reaches the end of its service life, the traditional response of replacement is far too costly compared to metallurgical repair..."
