What is an intelligent automatic spraying and painting machine for steel structures?

An intelligent automatic spraying and painting machine is an automated production line designed specifically for coating steel structural components such as H-beams, I-beams, box beams, and channels. The YOMI YM-PT-3070 model integrates 3D scanning, 12 intelligent spray guns (6 upper + 6 lower), and a closed drying room to deliver uniform, high-quality paint films with minimal human intervention. It supports both water-based and oil-based paints, and uses natural gas or propane for drying.

How does the 3D scanning system improve painting accuracy?

The built-in 3D scanning system automatically identifies the three-dimensional geometry of each workpiece and generates intelligent spray paths. This ensures the paint is fully utilized, sprayed evenly on all surfaces, and eliminates overspray or missed spots. The paint film thickness is also adjustable to meet specific corrosion-protection requirements.

How many spray guns does the YM-PT-3070 have and how are they arranged?

The YM-PT-3070 is equipped with 12 spray guns in total—6 on the upper side and 6 on the lower side—in an outer-eight distribution pattern. This dual-sided layout allows the member to be fully coated in one pass without needing to be turned over, significantly reducing cycle time.

What is the processing range and painting speed?

The YM-PT-3070 handles workpieces up to 700 x 3000 mm with a painting speed of 0.6–3 m/min. The conveyor supports a transfer weight of 800 kg/m, making it suitable for heavy steel components commonly used in construction, bridges, and industrial frameworks.

How does automatic spraying compare to manual painting in terms of efficiency and cost?

Automatic spraying lines drastically reduce labor intensity, cut paint waste through precision application, and deliver consistent coating quality that is hard to achieve manually. The YM-PT-3070 achieves waste dust emission below 2 mg/min, and the closed workplace with VOC processing interface ensures compliance with environmental regulations while lowering long-term operating costs.

What drying method is used and how is temperature controlled?

The machine features an intelligent drying room powered by natural gas or propane combustion. An electric contact temperature sensor automatically adjusts furnace output to maintain optimal drying conditions, so components can be hoisted immediately after surface drying—regardless of external weather or temperature differences.

What safety and environmental features are included?

The YM-PT-3070 operates in a completely closed workplace that keeps workers far from the painting environment. It includes a reserved VOC processing interface for emission control, and the high-efficiency filtration system ensures waste dust emission stays below 2 mg/min—meeting strict environmental standards.

What types of paint can be used with this machine?

The YM-PT-3070 supports both water-based and oil-based paints, giving manufacturers flexibility based on project specifications and local environmental regulations. The Graco (USA) spraying unit ensures reliable, high-performance paint delivery for both paint types.
