Discover our highly precise, industrial-grade PTA (Plasma Transferred Arc) and Laser Cladding systems engineered to extend the service life of heavy-duty tooling and cutting consumables.
Cutting picks, also known as cutting teeth or cutter bits, are the critical frontline contact components used in continuous miners, shearers, road headers, rotary drilling rigs, and road milling machinery. The operational efficiency of mining and excavation projects relies heavily on the durability of these components. However, aggressive geological environments expose cutting picks to extreme mechanical conditions, resulting in abrasive wear, impact fatigue, and severe thermal cracking.
SEO Insight & Information Gain: Traditional cutting picks rely solely on heat-treated steel bodies and brazed tungsten carbide tips. Our whitepaper demonstrates that modern, high-efficiency operations utilize Plasma Transferred Arc (PTA) Surfacing and Laser Cladding technologies to deposit cobalt-based or iron-based carbide matrices. This creates a secondary metallurgical shield, reducing overall pick body wear rates by up to 300%.
By integrating specialized wear-resistant cladding directly behind the tungsten carbide inserts, manufacturers protect the steel body from early wash-out erosion. This wear mechanism, if unchecked, leads to premature tip loss and catastrophic tool failure. Customization is no longer just about geometry; it is about tailoring the metallurgical microstructure of the cladding matrix to match the specific abrasive properties of local rock and soil strata.
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.

Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machines and Laser cladding machines for more than ten years, supported by a strong, multidisciplinary technical background.
When engineering cutting picks to withstand the intense friction and impact of geological excavation, choosing the correct hardfacing method is paramount. Both Laser Cladding and PTA (Plasma Transferred Arc) processes are highly effective, yet they offer distinct metallurgical characteristics, deposition dynamics, and economic properties.
Laser cladding utilizes a high-density, focused laser beam to melt the surface layer of the substrate steel and a concurrently fed metallic powder. Due to the highly concentrated energy density, the thermal input remains low, minimizing the heat-affected zone (HAZ) and thermal distortion. High-speed laser cladding is ideal for applying fine-grain, thin-layer overlays on cutting pick shafts and adjacent seating structures. It maintains high dimensional accuracy and yields dilution rates below 1%, preserving the precise properties of the alloy cladding material.
PTA uses a collimated plasma arc as its heat source to deposit thick layers of wear-resistant alloys. It excels in applying heavy, impact-resistant layers directly to the shoulders and wear zones of mining picks. PTA accommodates coarser, cost-effective hardfacing powders (such as tungsten carbide particles embedded in a nickel-based matrix) and provides excellent metallurgical bonding. The higher deposition rates of PTA make it a productive solution for high-volume automated cutting pick production lines.
Both processes produce a robust metallurgical bond with the substrate metal, far outperforming traditional thermal spray coatings that only provide mechanical adhesion. By selecting either high-speed laser cladding or PTA, manufacturers can prevent premature structural failure of the steel pick bodies, ensuring they wear at a rate proportional to the tungsten carbide insert.
Manufacturing custom cutting picks and the machinery required to clad them involves deep integration within raw material markets and manufacturing clusters. Shanghai Duomu operates at the center of the Yangtze River Delta industrial region, providing direct access to structural steel, tungsten carbide precursors, and advanced multi-axis robotics integration.
Supply Chain Resilience: China produces more than 80% of the world's primary tungsten supply. By utilizing a Chinese OEM manufacturer like Shanghai Duomu, international companies benefit from integrated materials sourcing. This removes cross-border supply chain volatility for critical hardfacing materials like tungsten carbide, chromium boride, and stellite alloys.
Additionally, our local manufacturing clusters allow for quick prototyping of custom pick geometries. Standardized production setups can be modified within days to accommodate specific customer designs, including conical picks, radial picks, and custom road-header teeth. This rapid design-to-production pipeline helps international buyers respond quickly to changing project specifications.
Global procurement teams must balance manufacturing cost-efficiency against regulatory compliance and localized technical support. At Shanghai Duomu, all equipment designs and cladding processes meet strict global industrial standards, including EU CE directives and ISO 9001:2015 quality management systems.
