Spray painting robots

Spray painting large industrial components requires precision and consistency across every part. As production volumes increase, maintaining that standard with manual application becomes a challenge. 

A spray painting robot automates the process and delivers repeatable results. At Ventherm, we provide complete robot solutions for heavy industry, combining 3D scanning with automatic programming so you can start painting without extensive setup.

What is a spray painting robot?

A spray painting robot is an automated system that applies paint, primers, or other coatings to industrial components. The robot follows programmed paths across the surface of each part, controlling spray angle, distance, and speed throughout the application. 

Spray painting robots are commonly used in industries where large or complex components require surface treatment. Wind turbine blades, offshore structures, railway equipment, and agricultural machinery are typical examples. The spray robot operates within a spray booth, where ventilation systems contain overspray and maintain air quality during the painting process. 

Benefits of spray painting robots

Manual painting takes time, and results can vary even between skilled operators. A spray painting robot removes that variability and brings additional benefits to heavy industry production. 

Consistent surface quality 

A robot paint sprayer applies the same amount of coating in the same pattern every time. This eliminates variations caused by operator fatigue or differences in technique, resulting in uniform finishes across your entire production. 

Reduced material waste 

Overspray is one of the largest cost factors in any paint operation. Spray painting robots optimize spray patterns and transfer efficiency, which means more paint ends up on your parts and less ends up in the extraction system. Many manufacturers report significant paint savings after implementing robotic solutions. 

Higher production capacity 

Once programmed, a paint spraying robot works continuously without breaks. This increases throughput and helps you meet demanding production schedules, particularly when coating large components. 

Improved workplace safety 

Paint fumes and particulates create health risks for workers. By automating the painting process, you remove operators from hazardous environments while maintaining productivity and simplifying compliance with occupational health regulations.

Self-programming spray paint robots with 3D scanning

Traditional industrial robots require extensive offline programming, which limits flexibility and adds time to the production process. Ventherm’s spray painting robot solutions take a different approach. Our systems use 3D scanning technology combined with automatic programming to eliminate manual robot programming entirely. The automatic painting robot scans the unpainted part, matches the scan with the CAD model, and automatically generates the optimal paint paths for each component’s exact size, shape, and position. 

The technology is well suited for heavy industry applications, where components like wind turbine blades and offshore transition pieces vary in size and position. The system also recognizes part position and orientation automatically, allowing for production with minimal manual supervision.
