Reciprocator + Gun Control System
Powder only fires when a part is there.
An integrated control system combining part-presence detection, gun triggering, and conveyor speed synchronisation — eliminating the single largest source of powder waste in automatic lines: guns spraying into empty space.
Why this product
Automatic guns fire between parts continuously.
In a typical automatic powder coating line, guns run at full output as long as the line is running — regardless of whether a part is actually in the spray zone. Every gap between parts on the conveyor is powder fired into empty space, recovered at lower efficiency, and processed through the filter. This waste adds up to 15–35% of total powder consumption on most lines.
- Part-presence detection (photoelectric or encoder) triggers powder discharge only when a part is confirmed in the spray zone
- Conveyor speed synchronisation — film build per part remains consistent regardless of line speed changes
- 15–35% typical powder waste reduction depending on part spacing and line configuration
- Reduces over-spray inside the booth — extends filter life, improves cyclone recovery efficiency
- Retrofittable onto existing OptiFinish and third-party booth and reciprocator installations
- PLC-based integration with standard control panel — no specialist programming environment required
How it works
Detect, trigger, stop waste
Part detection
A photoelectric sensor or conveyor encoder positioned at the booth entry detects when a part enters the spray zone. The signal is processed by the PLC control unit in real time — triggering gun activation within milliseconds of part entry.

Where it's used
Applications & use cases
- Conveyorised production lines with variable or large gaps between parts
- Operations targeting powder material cost reduction as a primary KPI
- Automatic lines where guns currently run at full output throughout the shift
- Lines with mixed part sizes — detection adapts to each part individually
- Retrofit onto existing booth and reciprocator installations (third-party compatible)
- Any automatic powder coating line where powder material cost is significant
