Aroma Diffuser Reservoirs & Lids
Scope an injection-molded diffuser tank and cover around the working liquid, fill line, cleaning method, closure and acceptance checks.
Describe the actual fluid and exposure
Provide the working liquid or its composition, concentration range, contact time, operating temperature and cleaning agents. Include prolonged contact around the fill line or closure if it can occur. Ask for grade-specific data and agree how the candidate material will be checked on molded samples.
Define which surfaces need to seal
Show the fill line, reservoir rim, lid seating area and seal groove if there is one. Identify the gasket specification or mating component and define how it is held in place. For a leak check, document the liquid, fill level, orientation, duration and acceptable result for the intended assembly.
Separate fit checks from exposure checks
Use matched molded parts to check closing, seating and key dimensions. For contact testing, agree the liquid and cleaning exposure and check for visible changes or loss of function under the specified conditions. Keep records tied to the resin grade and part revision used for the trial.
Frequently asked questions
Is there one resin suitable for every fragrance formulation?
Select candidates for the actual formulation and exposure, then verify the selected grade on a molded part under the agreed conditions. Temperature, exposure duration and stress in the assembled part can affect compatibility.
What should the first sample report cover?
Record part and drawing revision, resin grade, sample condition and agreed checks. Include the tank-to-lid fit, relevant dimensions, and any agreed leakage or liquid-contact observations.
