Indiana Powder Lines Built for Long and Heavy Parts
Trailer crossmembers, equipment panels and long fabrications put a powder line under load in ways small parts never do. Conveyor capacity, turning radius, oven dwell and washer spray coverage all have to handle long and heavy steel. Indiana manufacturers building lines for that kind of work need a layout that respects the part. Double D installs powder coating lines and the mechanical systems that connect each stage.
Discuss your installationConveyor capacity and turns
Heavy parts need a conveyor rated for the load per hanger and per foot. Long parts need wide turns so they do not swing into walls, booth openings or other parts. Turn radius and part length go into the layout from the start.
Heavy steel and oven dwell
Thick steel takes longer to reach cure temperature than sheet metal. That means more oven length or slower line speed. Dwell time is set by the heaviest part regularly on the line.
Washer coverage on large shapes
Spray nozzles in each washer stage need to reach the whole part, including inside channels and recesses. Large or deep parts may need additional risers or nozzle angles.
- Riser spacing matched to part height
- Nozzle angles for channels and recesses
- Drain time between stages to limit carryover
- Tank volume sized for the part surface area
Load and unload stations
Hanging and removing heavy parts takes time and often hoists. Load and unload areas need space, lifting equipment and enough conveyor length to keep the line moving while parts are hung.
Planning a booth or oven project in Indiana
Crews mobilize from Houston; Indiana is roughly 850 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Indiana is concentrated around Indianapolis, Fort Wayne, Evansville, and South Bend. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive and powertrain, RV and trailer manufacturing, steel, and aerospace components.
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 a powder line handle trailer-length parts?
Yes, with conveyor capacity, turn radius, booth openings and oven length designed for them.
Why do heavy parts come out under-cured?
Thick steel needs more time at temperature. Oven dwell or line speed needs to match the heaviest parts.
Do we need hoists at load and unload?
For heavy parts, usually. Plan the space and lifting equipment with the line.
How do we get washer spray inside channels?
Riser spacing and nozzle angles are adjusted to reach recesses.
What information helps plan a line?
Part dimensions and weights, production rate, coating spec and the building footprint.
