Identify the exact liquid, concentration, temperature and contact duration. General polyethylene chemical resistance does not validate a finished tank with stressed corners, inserts and seals. Include cleaners, rinses and intermittent exposure, not just the stored liquid. Obtain grade-specific supplier advice and agree representative testing. If a customer changes detergent concentration or operating temperature, treat that as a design change. Fuel, hazardous chemicals and pressure duties require a separate technical review.
What to send for a useful review
- Medium, concentration and contact duration
- Continuous, peak and minimum temperature
- Gaskets, connections and leak test method
- Test conditions and pass/fail limits
Agree acceptance before tooling
General guidance. Validate resin, geometry and assembly in actual operating conditions. This is not a product certification or production commitment.
Cleaning robots & scrubber tanks
Develop clean-water tanks, recovery tanks and bodies around your machine layout. The brochure describes a scrubber project with complex tooling, alignment fixtures and airtightness testing. Autonomous models need additional sensor, battery and service-access review.
