• Production-related dimensional variations for length dimensions as well as distortion-related form, position and angle deviations determine the dimensional accuracy immediately after the production of the molded part.
  • The achievable dimensional precision is determined, among other things, by the production and quality assurance effort that can be mobilized by the molding manufacturer. The tolerance series according to DIN ISO 20457 are intended for this purpose. Precision special production is to be classified like precision manufacturing.


Among other things, you can use our software products PolTolerances or PolTolerances-AC to determine the tolerance series according to DIN ISO 20457. You can find the corresponding downloads on our homepage.
