Automatic Powder Coating Gun
Volume. Repeatability.
The Automatic Powder Coating Gun makes electrostatic powder coating continuous and repeatable for high-volume production lines. Mounted on a reciprocator or robot, it works in a fixed or moving array; voltage, current and powder flow are managed centrally to give every part a consistent film thickness. Integrated with the Smart and Smart AI control platforms and line automation, it engages in sync with conveyor speed, part detection and recipes.
Consistent Quality for Series Production.
The automatic powder coating gun is designed for continuous coating on conveyorized production lines without operator intervention. The guns are mounted in an array on a reciprocator; as parts travel past on the conveyor, an up-and-down stroke covers the entire surface. The number and spacing of guns are defined per project according to line width and part size.
The kV, µA and powder output of each gun are managed individually from the central control unit and run in sync with the conveyor and reciprocator motion. When integrated with the Smart and Smart AI platforms, all parameters are stored as recipes; the same part is coated with the same film thickness every time, giving repeatable, operator-independent results.
Built for Automation.
High Volume
Operator-independent operation for continuous production.
Fixed or Moving Array
Flexible layout with reciprocator or robot mounting.
Repeatable Quality
Consistent film thickness on every part with recipes.
Automation Integration
Synced with Smart / Smart AI control and line automation.
Head Groups and Nozzle System.
The head group of the automatic gun is the critical component that holds the nozzle, deflector and electrode assembly together. Depending on part geometry, flat, angled (45° / 90°) or rotating nozzle heads change the shape and direction of the powder cloud.
Choosing the right head group delivers even film thickness and high transfer efficiency in corners, recesses and cavity areas. Watch the video to see how head groups work and the different nozzle types.

Robot Integration.
Automatic guns are mounted on different automation systems according to part geometry — from single-axis reciprocators to multi-axis robotic motion.
Single-Axis Reciprocator
Moves automatic guns up and down on a single vertical-stroke axis; delivers repeatable, uniform coating coverage on flat and tall parts.
Explore
Two-Axis Reciprocator
Adds in/out motion to the vertical stroke to move the guns toward and away from the part; delivers consistent powder coverage on surfaces of varying depth and recesses.
Explore
Three-Axis Systems
Adds a third axis to the vertical stroke and in/out motion; delivers wider, uniform coating coverage on variable-profile parts with more degrees of freedom.
Explore
Robot Integration
Mounts automatic guns on multi-axis / 6-axis robotic motion; working integrated with Smart AI, it delivers precise coating on complex, deep and shadowed geometries as well.
ExploreCast Cascade Technology.
The cascade is the heart of every gun, converting low voltage into high electrostatic voltage. Its durability directly determines gun life and coating quality — and on automatic lines running continuously, that durability is even more critical.
Add-On Cartridge Type
A cartridge-type cascade attached externally to the body is exposed to moisture and dust through its connection points; under vibration and continuous operation it is easily damaged and fails.
Cast in One Piece with the Body
Our cascade is cast in one piece with the gun body and fully encapsulated using a special vacuum technique. It is ultra-resistant to moisture, dust and continuous line operation.

How Does Corona Charging Work?
From low voltage to surface adhesion — the six steps of electrostatic powder coating.
Low Voltage
The gun is supplied with a low, safe DC voltage from the control unit.
Coil
The coil converts this low voltage into a high-frequency oscillation, preparing it for amplification.
High-Voltage Cascade
The cast cascade boosts the voltage to around 100 kV — the source of the gun's charging power.
Electrode and Ionization
The strong electric field at the electrode tip ionizes the surrounding air (corona discharge).
Charging the Powder
The ions formed charge the powder particles leaving the gun negatively.
Choose Your Setup.
Short / Medium / Long Body
A short, medium or long body is selected according to booth depth and part size. The long body reaches further in deep booths and on large parts, while the short body offers easier positioning and mounting in tight spaces. Body length is defined per project together with reciprocator stroke and gun spacing.
OKP Control Panel
An automatic control cabinet that manages multiple guns from a single point. kV, µA and air settings are made individually for each gun, and the entire line is monitored from the touchscreen. With PLC integration it runs in sync with conveyor and reciprocator motion, enabling recipe-based, repeatable production.
Reciprocator Package
A complete application cell with a single- or two-axis reciprocator that moves the guns in a vertical stroke. Stroke length, speed and number of guns are engineered according to part size and line capacity.
