The defines acceptable manufacturing deviations to: for part sizes based on manufacturing effort and tooling
Whether using injection molding, compression molding, or rotational molding, achieving high precision in plastics requires accounting for unique polymer characteristics like shrinkage, moisture absorption, and thermal expansion. 🛠️ The Purpose of ISO 20457 or rotational molding
In the manufacturing of plastic parts, applying standard metal tolerances (like ISO 2768) is not practical. Plastics behave differently during and after cooling.
