Industrial spray coating for demanding surfaces
Industrial spray coating is one of the most precise processes for the industrial coating of wood, furniture, construction elements, plastics, metals and glass. The quality of the material application determines the look, feel and protective function of a surface. At Venjakob, we develop automated spray coating lines that ensure controlled coating application, low reject rates and efficient use of materials. Industrial robotics and digital process monitoring support consistent quality, even with varying geometries and quantities.
VEN SPRAY spray coating lines
Our VEN SPRAY spray coating lines have a modular design and can be precisely adapted to different production requirements. They enable uniform atomisation, high material efficiency and flexible parameterisation via the control system. We integrate VEN SPRAY systems seamlessly into complete coating lines - from pre-treatment and material handling to drying and exhaust air purification.

The industrial spray coating process chain
Efficient industrial spray coating is only achieved when all upstream and downstream process steps are seamlessly interlinked. From safe workpiece guidance and optimally prepared surfaces to drying, exhaust air purification, industrial robotics and intelligent process monitoring - every step influences the quality of the final result. The Venjakob process chain shows how these individual steps can be combined in a modular way, depending on the material, throughput and degree of automation.
Robot-assisted spray painting
Different spray painting processes are used depending on the surface, coating system and quality requirements. At Venjakob, we integrate all relevant processes and select the optimum technology for the material, geometry and series requirements.
Industrial spray coating: The mode of action
A precise spray painting process is the result of the interplay between the detection of the workpiece, optimum coating parameters and a stable, guided application. Industrial robotics or automatic spraying systems ensure uniform coating thicknesses, while air guidance and overspray separation ensure quality in the booth. The process can be fully automated and can be flexibly configured for different geometries and materials.
Workpiece detection
The geometry is captured using a scanner or camera, and the trajectories are automatically calculated and precisely adapted to the workpiece.
Material preparation
Pressure, material quantity and viscosity are regulated in a stable manner - for a constant coating application regardless of temperature or material batch.
Coating application / atomisation
Airless, airmix or electrostatic spraying systems apply the coating in a controlled manner. Industrial robotics enable reproducible paths and defined coating thicknesses.
Airflow & overspray separation
Homogeneous air flows keep the spray mist in the process chamber, while wet or dry separation reliably removes the overspray.
Transfer to the next process step
The components leave the cabin without surface contact and go directly into flash-off after coating in industrial production, IR, UV or coating drying systems.
Industrial spray coating: sustainable and safe
Sustainability is becoming increasingly important in industrial finishing. Energy-efficient air and coating management reduces consumption and emissions. At the same time, safe system technology ensures high process quality and protection for operating personnel. With exhaust air systems, systems meet legal requirements for VOC reduction and enable energy-optimised production conditions.
- Energy-efficient air routing
- Reduced VOC emissions
- Optimised coating consumption
- Safe filter and exhaust air technology
- Explosion protection and occupational safety
Future trends in spray painting
Industrial spray painting is developing rapidly because production lines today demand greater precision, shorter changeover times and verifiable quality stability. Modern systems are increasingly merging with digital systems: Sensor technology, AI-supported analysis and adaptive robot movements make finishing processes calculable, documentable and optimisable. At the same time, new coating systems and energy-efficient application technologies are emerging that reduce material consumption and VOC emissions.
How does the airflow affect the quality of industrial spray coating?
Stable air flow prevents turbulence in the spray jet, minimises overspray and ensures uniform coating thicknesses. It is crucial for the gloss level, structure and flawlessness of the surface. Systems are designed so that paint mist is captured efficiently and air is conditioned cleanly.
What defects occur during industrial spray coating - and how can they be prevented?
Typical faults are orange peel, runners, wetting faults or uneven layer thicknesses. These are caused by unsuitable parameters, unstable air flow or incorrect nozzles. Precise process control, automatic monitoring and robot-supported movement paths minimise these risks.
In which industries is industrial spray coating used?
Industrial spray coating is used in the wood and furniture industry, automotive, aviation, component manufacturing, metals processing, plastics technology and glass finishing.
For which materials is industrial spray coating suitable?
Wood, MDF, metals, aluminium, plastics, composites, glass and construction elements can be coated using the spray process. The right processes and a suitable coat are crucial.
What applications can be realised with industrial spray coating?
Typical applications include furniture parts, doors, profiles, vehicle components, housings, technical components, fronts and special surfaces. Functional coatings such as adhesive primers or protective coatings can also be sprayed.
What is industrial spray coating?
Industrial spray coating is a process in which coat is finely atomised and evenly applied to a surface. It is suitable for flat and complex geometries and is used in automated coating lines. Modern systems reduce overspray, improve surface quality and enable reproducible results.
