In the high-stakes world of underground mining and excavation, the mining pick is the frontline soldier. Traditional picks face rapid wear, thermal degradation, and mechanical failure under extreme geological conditions. Shanghai Duomu, a leader for over a decade in PTA and Laser cladding, provides the ultimate technical answer: Information Gain through surface engineering. By applying specialized alloy powders—often enriched with Tungsten Carbide—via Plasma Transferred Arc (PTA) or Laser Cladding, we extend the service life of mining picks by 300% to 500%.
Our technology doesn't just "coat" the tool; it creates a metallurgical bond with a low dilution rate, ensuring the hardfacing layer retains its maximum hardness without being contaminated by the substrate material.
Why source from China? The answer lies in the integration of the complete supply chain. From the sourcing of high-purity rare earth powders to the manufacturing of 6-axis robotic arms, Chinese factories offer an unparalleled price-to-performance ratio. At Shanghai Duomu, we leverage an independent R&D team to customize equipment for specific coal seams and rock types found globally, from the Australian Outback to the Siberian Tundra.
The industry is moving toward "Intelligent Remanufacturing." Rather than discarding worn components, global enterprises are adopting onsite cladding systems. We are seeing a shift from traditional manual surfacing to Automated Laser Cladding, which reduces heat-affected zones (HAZ) and minimizes distortion. This is essential for precision components like hydraulic rods and valve seats.
As noted in our technical white papers, achieving a high-quality overlay is dependent on the dilution rate. In PTA hardfacing, our systems allow for precise control over the arc intensity, ensuring that the alloy powder melts into the surface with minimal penetration into the base metal. This preserves the "pure" properties of the carbide, crucial for abrasive mining environments.
For global mining conglomerates, the "Real Cost" is not the price of a single pick—it is Downtime. When a continuous miner stops because the picks have worn out, the lost revenue per hour is staggering. Our solution provides:
PTA (Plasma Transferred Arc) is generally more cost-effective for thick layers (2-5mm) and offers high deposition rates, making it ideal for large mining picks. Laser Cladding provides much lower heat input and higher precision, which is better for delicate components or when thermal distortion must be avoided at all costs.
Yes. Our Plasma and Laser cladding systems are designed with open communication protocols (such as EtherCAT or Profinet), allowing seamless integration with ABB, KUKA, FANUC, and other industrial robot brands.
Our feeders support a wide range of spherical and crushed powders, including Nickel-based alloys, Cobalt-based (Stellite), Tungsten Carbide (WC/Co), and customized stainless steel powders.
Absolutely. Shanghai Duomu offers comprehensive technical training, including parameter optimization, dilution rate control, and routine maintenance, either onsite or via remote video support.
I have an independent R&D team, which develops, produces and sells plasma cladding machine equipment. The welding machine has stable performance and can maintain efficient long-term operation. In addition, the laser cladding equipment sold by the company can effectively support large-scale remanufacturing projects.
