Spray 2K-SB paint with robotic electrostatic twin guns

Automate, save up to 35% of paint, 60% of cycle time, and obtain high finishing quality with Sames Nanocoat electrostatic TRP502 robotic gun spraying combined with a process arm 2K antenna embedded onto the robot.

Description

Base and hardener are pumped at low pressure until the process arm onto the robot.
During the execution of the coating trajectories, both components are dosed with volumetric gear-pumps and mixed just before spraying at high flow rate with TRP502 twin guns.
The robot itself is synchronized with 3 external axes, giving up to 9-axes robotic solution able to reach almost all areas of the truck bed. A final manual touch-up & curing stage is performed after.

Let's get in touch

  • How can I increase productivity on large truck and bus components without compromising quality?

    Looking to boost productivity on large truck and bus parts without compromising on finish? Discover how electrostatic high-flow guns like the TRP502—and even rotary bells—offer tailored solutions to meet your performance and quality goals.
    Electrostatic spraying with high-flow guns, like the TRP502, enables fast and efficient coverage of large surfaces—such as truck cabins, chassis, and bus panels—while maintaining excellent finish quality. Combined with optimized robot paths or well-trained operators, this solution dramatically shortens cycle times.
    The TRP502 is a unique solution on the market, offering unmatched paint flow capacity combined with electrostatic efficiency. Unlike conventional high-flow systems that often sacrifice finish, the TRP502 delivers both speed and a smooth, consistent film build—making it ideal for manufacturers seeking high productivity without compromising visual quality.
    As an alternative, electrostatic rotary bell applicators can be considered for applications requiring even higher transfer efficiency and a premium-level finish. While the overall paint flow is slightly lower, rotary bells deliver superior atomization and material savings, making them the preferred option for projects where surface appearance and transfer efficiency are the top priorities.

  • Is electrostatic spraying effective on complex geometries like truck chassis or underbodies?

    Yes, electrostatic spraying is highly effective for complex geometries such as chassis frames, tubular structures, and underbodies. Its natural wrap-around effect ensures better coverage of hard-to-reach areas, reduces overspray, and delivers a more uniform film build—even on angular parts.
    There are, however, two specific considerations:
    • Faraday cage limitation – deeply recessed or enclosed areas can resist electrostatic charge. In such cases, the solution is simple: temporarily disable the electrostatics during that phase of the application.
    • Edge effect – electrostatic charge tends to concentrate on edges, leading to potential overcoating. This can be finely controlled through proper adjustment of voltage settings and optimized spray paths. In fact, controlled edge buildup can become an advantage for corrosion protection, since edges are often the most vulnerable areas on metal parts.
    Once these aspects are mastered, the benefits of electrostatics—such as improved material transfer, part-attracted deposition that compensates for minor positioning variances, and high application consistency—make it a superior spraying method.
    Electrostatic spraying is more than a technique—it’s a culture. Once adopted, it’s hard to go back.

  • How can I reduce paint consumption in truck & bus painting operations?

    Electrostatic spraying greatly reduces paint consumption by improving transfer efficiency—less overspray means lower paint use, reduced maintenance, and consistent, high-quality finishes.

    Fast, efficient color-change systems with Upside valves and peripherics help minimize waste and downtime, especially in operations with frequent color switches.

    For specialized or small-batch production, Sames offers high-performance solutions like the Cyclomix® Evo 2K dosing machine for precise mixing with minimal waste, and manual spray guns such as the Nanogun (electrostatic Airmix® or airspray), Xcite® (Airmix®), and Fpro (airspray)—all designed for top-quality finishes and maximum paint savings.

    Improving transfer efficiency remains the most effective way to cut paint use while maintaining productivity and quality.
