Expanding an Existing Powder Coating Line in Michigan
When a powder line becomes the bottleneck, plants usually look for ways to add capacity without replacing everything. Michigan suppliers and Detroit-area manufacturers expand lines by adding a booth, lengthening the oven, adding washer stages or raising line speed. Each change ripples through the rest of the line. Double D plans and installs powder line expansions and connects the new equipment to what is already running.
Discuss your installationFinding the true bottleneck
Raising conveyor speed only works if every stage can keep up. The oven may lack dwell, the washer may lack stage length, or the booth may not coat fast enough. We look at each stage against your target speed before recommending changes.
Common expansion moves
Each of these options adds capacity in a different way, and some can be combined.
- Add oven modules to lengthen cure time
- Add a second booth for color or capacity
- Extend washer stages or add a stage
- Upgrade conveyor drive and take-up for higher speed
Working around a running line
Expansions often happen while the line runs. Prefabricating new modules, staging equipment and making tie-ins during planned shutdowns keeps lost production down. Utility upgrades for added burners or fans should be done before the tie-in window.
Rebalancing after the change
Longer ovens change exhaust and burner demands. Added booths change building air balance. After the expansion, we check oven profiles, booth airflow and plant air balance so the line runs correctly at the new speed.
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
Can we add capacity without replacing our line?
Often. Extending the oven, adding a booth or adding washer stages are common approaches.
How do we know which stage is limiting us?
Compare each stage's capacity with your target line speed. The shortest one sets the limit.
Can expansion work happen while we keep running?
Much of it can be staged and prefabricated, with tie-ins during planned shutdowns.
Will a longer oven need more gas?
Usually. Added oven length means more heat input, so gas supply should be checked.
Does adding a booth affect building air?
Yes, if the booth exhausts outside. Make-up air may need to be increased.
