In principle, plastics are subject to eight to ten times greater thermal expansion than metals. This means that there is a dimensional change due to moisture absorption of up to 1%, as well as a dimensional change due to the slow reduction of residual stresses and temperature over the longer term. We can therefore not give a 100% size guarantee. You do have the option to receive 1% extra length for free to compensate for this shrinkage.
In addition, we do not guarantee the progress of any shrinkage processes, as this can differ per product.
Our dimensional tolerances are based on the DIN ISO 3302-1 class L3 standard in the following table:
|Nominal size in cm||Class L3 ±|
