Automatic Powder Booths on Michigan Conveyor Lines
On a conveyor line, the powder booth has to coat every part consistently at line speed, shift after shift. Michigan automotive suppliers and Detroit-area manufacturers running automatic powder booths depend on gun movers, reciprocators, recovery and controls that work together. Double D installs automatic powder booths and integrates them with conveyors, ovens and plant utilities.
Discuss your installationAutomatic guns and reciprocators
Automatic guns mount on reciprocators or fixed stands that move vertically while parts pass by. Gun count, stroke and spacing are set for part size and line speed. Manual touch-up stations at the booth entry or exit handle recesses the automatic guns miss.
Conveyor openings and part spacing
Parts enter and leave through silhouette openings sized to the largest part. The openings have to be large enough for clearance but not so large that powder escapes. Part spacing on the conveyor affects gun triggering and transfer efficiency.
- Silhouette openings sized to the largest part
- Consistent hook spacing and orientation
- Clean hooks for a good ground path
- Part detection for gun triggering
Recovery for high-volume colors
Line booths often run a few colors for long periods, which favors cyclone or cartridge recovery. Recovered powder is sieved and blended with virgin powder. Recovery choice affects color change time and booth design.
Integrating with the line
The booth sits between pretreatment and the cure oven. Its exhaust, controls and safety interlocks connect with the rest of the line. We coordinate booth installation with conveyor and oven work so everything starts together.
Planning a booth or oven project in Michigan
Crews mobilize from Houston; Michigan is roughly 1,100 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Michigan is concentrated around Detroit, Grand Rapids, Lansing, and Flint. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive assembly and suppliers, office furniture, tool and die, and EV batteries.
Cold winters mean make-up air heaters are sized for sub-freezing intake, and booth or oven placement has to account for frost lines, snow loads on roof penetrations and winter slab work.
Frequently asked questions
How many automatic guns do we need?
It depends on part size, line speed and coating thickness. Gun count is set during booth design.
Can an automatic booth handle different parts?
Yes, with gun programs and part detection. Very different part shapes may need manual touch-up.
What is the difference between cyclone and cartridge recovery?
Cyclones separate powder by spinning it out of the airstream and suit fast color changes. Cartridges filter powder directly and suit long single-color runs.
Do you connect booths to existing conveyors?
Yes. We align openings and coordinate controls with your conveyor.
How do we keep coating thickness consistent?
Stable gun settings, clean grounding, consistent part spacing and proper powder flow.
