Powder Coating Line Demonstrations: Test Your Own Metal Parts
Buyers evaluating an electrostatic powder coating line should require a demonstration using their own metal workpieces, covering booth, recovery, oven and conveyor behavior before committing to a quotation.
Ask the supplier to run your own metal parts through the line before you accept performance claims. A demonstration on sample panels says little about how an automatic powder booth, powder recovery, curing oven and conveyor behave with your part geometry, hanging density and production rhythm.
For the request for quotation, specify the workpiece sizes, racking arrangement and target throughput you want demonstrated. Ask whether the trial will use your powder and your preferred curing energy option among electric, gas, diesel or coal, and how recovery efficiency will be shown. During the demonstration, watch for consistent coverage on edges and recesses, powder buildup in the booth, and whether the conveyor speed matches the oven dwell you need.
For acceptance testing, agree in advance on what counts as a pass: visual coverage, cured film appearance, and repeatability across a run of parts. Ask the supplier to record settings used so your team can reproduce them.
Before requesting a quote, confirm with the supplier which line elements will be included, what workpiece samples they need for a trial, how the demonstration will be witnessed and documented, and which curing energy option the quoted configuration assumes. Treat catalog values as reference only until verified on your parts.
