Aroma Diffuser Housing RFQ Checklist

Prepare a useful tooling RFQ for aroma diffuser plastic parts by documenting assembly, cosmetic surfaces, liquid exposure and first-sample acceptance.

Send a part list and one assembly section

List each custom molded part with its revision and intended function. A single section through the cover, tank and base helps identify which parts locate the mist outlet, mount the electronics and meet the user during refilling.

Mark visible, wet and warm surfaces

Separate permanent fluid contact from occasional splashes, condensate and cleaning. For a lamp or heated unit, mark the expected temperature at the nearby plastic. Set cosmetic criteria for surfaces that are visible in ordinary use and during operation.

Attach the details that drive tooling decisions

Point out shell thickness transitions, intended clips or screw bosses, draft-sensitive features and the mating surfaces that locate the cover. Add notes for restricted gate, parting-line and ejector marks. A review can then compare mold access and surface requirements before the design is locked.

Quote from one agreed acceptance list

For each item, specify how to check it and which parts must be assembled. Useful checks may include joint flushness, lid seating and opening, outlet alignment, visible appearance and tank leakage under the conditions you define. Identify who provides the mating parts and which tests are part of the quote.
