Thermal spray processes have long been recognized as a vital technology for enhancing surface performance across a wide range of industries. From aerospace turbine blades to automotive components, from petrochemical pumps to large-scale power generation boilers, these coatings provide essential wear resistance, corrosion protection, and thermal insulation. In recent years, the integration of automation and robotics has begun to transform how thermal spray equipment is deployed in manufacturing facilities. At Jinan Tanmng New Material Technology Co., Ltd., we design and supply advanced robotic-ready thermal spray systems that allow manufacturers to achieve highly repeatable coating results at scale while reducing human risk and material waste. Our systems are engineered for seamless integration with industrial robotic cells, giving manufacturers a path toward high-volume, automated operations that meet the rigorous demands of modern production environments.
Automation in thermal spray is not just about speed; it is about creating a smarter, more reliable process. By incorporating robotic solutions, manufacturers can ensure that each part receives consistent treatment, traceable data capture, and controlled environmental exposure. This trend is reshaping industries that rely heavily on surface protection and functional coatings, and companies like Tanmng are at the forefront of providing turnkey solutions that make this transition feasible and profitable.
Automation has become a necessity rather than a luxury for manufacturers who require precision, efficiency, and repeatability. Manual thermal spray operations, while flexible, are prone to variability in coating quality, resulting in rework, scrap, and inconsistent product performance. Automated systems address these challenges by combining precise control of thermal spray guns with robotic motion planning, enabling uniform coatings across complex geometries and large production runs.
The adoption of automation also aligns with broader manufacturing trends toward Industry 4.0. Smart factories increasingly demand equipment capable of integrating into digital production networks, feeding real-time data into quality assurance systems, and adapting processes on the fly to maintain product specifications. Thermal spray equipment that is robotic-ready offers a bridge to this digital ecosystem, allowing manufacturers to remain competitive in sectors where consistency and traceability are paramount.
One of the primary advantages of automating thermal spray equipment is repeatability. Even highly skilled operators can introduce subtle variations in spray angle, distance, and speed, all of which affect coating thickness and adhesion. Robotic arms programmed with precise paths and motion sequences eliminate these inconsistencies, ensuring that every component receives the same high-quality treatment.
Throughput is another critical factor driving automation. Robotic cells can operate continuously without fatigue, handling hundreds or thousands of parts per day with consistent results. This capability is especially valuable in industries like automotive and petrochemical, where high-volume production is essential. Moreover, automation reduces human exposure to high-temperature materials, toxic powders, and airborne particles, enhancing operator safety while maintaining strict environmental standards.
Material efficiency is also significantly improved. Automated systems apply coatings with precision, minimizing overspray and waste. This not only reduces production costs but also lowers environmental impact—a key consideration for companies operating under stringent sustainability regulations. In effect, automation allows manufacturers to achieve better quality, faster production, and greener processes simultaneously.
Integrating robotics into thermal spray operations requires careful consideration of system layout, payloads, and motion requirements. Different levels of automation—from manual-assisted setups to fully autonomous robotic cells—offer varying degrees of efficiency and control.
Thermal spray automation can follow a staged approach depending on production needs and investment considerations. Entry-level systems, often termed manual-assisted, allow operators to guide spray guns along predefined paths while robotic actuators manage consistent motion and feed rates. This hybrid approach is ideal for manufacturers transitioning from fully manual processes and helps reduce operator error without a complete overhaul of existing production lines.
Semi-automatic cells offer more extensive automation, handling repetitive motions and complex sequences while still requiring operator supervision for loading, part orientation, or process initiation. Fully robotic cells, however, automate the entire spray operation—from part loading and positioning to gun movement, rotation, and coating application—minimizing human intervention and maximizing operational efficiency. Such cells are particularly suited for high-volume production lines where precision and consistency are non-negotiable.
Designing a robotic thermal spray cell requires careful attention to robot payload, reach, and the number of motion axes. Thermal spray guns, whether flame, plasma, or supersonic, vary in size and weight, and robots must handle these tools without compromising speed or accuracy. Multi-axis robots, typically six or seven axes, allow the spray gun to access complex part geometries, ensuring complete coverage even on components with intricate shapes or internal surfaces.
The reach of the robot arm must be sufficient to cover all required spray paths while maintaining optimal gun-to-substrate distance. In large-scale applications, such as coating rolls for the paper industry or turbine components, multiple robots may operate in parallel within the same cell to achieve consistent results without bottlenecks. Properly designed cell layouts, including part conveyors, rotating fixtures, and safety enclosures, are critical for maximizing efficiency and minimizing downtime.
Automation not only improves mechanical precision but also enables sophisticated process monitoring and data traceability, which are increasingly demanded in regulated industries.
Advanced thermal spray systems can integrate sensors to record key process parameters such as temperature, spray velocity, feedstock flow, and gun-to-substrate distance. This data is automatically logged for each part or batch, allowing manufacturers to trace coating history, verify compliance with quality standards, and analyze deviations in real time.
Quality assurance feedback loops enhance this capability. If a parameter drifts outside acceptable limits, automated controls can adjust gun speed, power, or feed rate immediately, preventing defects and ensuring uniformity across production. For industries such as aerospace, medical devices, or high-performance tooling, this level of traceability is essential for certification, auditing, and customer assurance.
In addition, integrated software platforms allow manufacturers to visualize process trends, monitor equipment health, and optimize production schedules, providing actionable insights that improve overall efficiency and reduce operational costs.
Despite its benefits, automating thermal spray equipment presents several engineering challenges, especially in terms of fixturing, accessibility, and multi-surface coating.
Custom fixturing is often required to hold parts securely during spraying while avoiding obstruction of the robotic path. Line-of-sight limitations may prevent the robot from accessing hidden or recessed surfaces, making full coverage a challenge. Multi-face coating strategies, including part rotation or secondary robotic arms, are necessary to achieve uniform coatings on all surfaces.
Complex shapes such as turbine blades, rollers, or large pipelines require thoughtful integration of fixtures and robot motion to maintain the correct spray angle, distance, and overlap. These considerations are vital for high-value components where coating consistency directly affects performance and lifespan.
At Tanmng, our thermal spray systems incorporate specialized tooling, angled guns, and adaptable end-effectors to address these challenges. Robots can manipulate parts in multiple orientations while precisely controlling spray parameters to ensure uniform deposition. Our solutions also include programmable multi-arm configurations, allowing simultaneous coating of multiple surfaces or parts to further increase throughput. By providing flexible automation options, we enable manufacturers to maintain quality across complex and high-volume production scenarios while simplifying integration into existing lines.
The future of thermal spray automation is increasingly digital. Closed-loop control systems monitor real-time parameters and adjust spray conditions automatically, ensuring optimal coating quality with minimal human intervention.
Digital twins are virtual replicas of robotic spray cells that allow engineers to simulate operations, predict maintenance needs, and optimize spray paths before actual production. This capability reduces trial-and-error setups, lowers downtime, and improves efficiency across the facility.
Hybrid processes are emerging as well, combining thermal spray with additive manufacturing techniques to create multifunctional surfaces in a single production cycle. For example, wear-resistant coatings can be applied over complex geometries that have been 3D-printed or machined, enabling manufacturers to reduce production steps and achieve performance characteristics previously unattainable with conventional methods.
Collectively, these innovations are positioning thermal spray equipment as a cornerstone technology for Industry 4.0, enabling smarter, faster, and more precise surface engineering.
