A defect is a symptom, not a complete diagnosis. Record location, frequency, material lot, photographs and the conditions of good and bad parts. Bubbles or pinholes may require checking fusion and powder condition; discoloration may require checking heat history, contamination or pigment. Avoid changing material, temperature and rotation together, because the cause becomes harder to identify. Agree whether the defect affects appearance, function or both, and confirm the correction on a representative repeat run.
What to send for a useful review
- Resin grade, data sheet and batch traceability
- Texture, colour reference and visible surfaces
- Nominal wall, minimum wall and inspection map
- 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.
Non-pressure water & industrial containers
Review shape, supports, filling, draining and cleaning together. For export, compare packed volume and part cost. Potable water, food contact and hazardous liquids require evidence for the grade, fittings and destination.
