Manufacturing tolerances
Many factors involved in the rubber article production process can affect the final product dimensions, e.g. the proportion of materials used, curing and post-curing times, vulcanisation temperature and pressure or inserts of other materials. Even the storage humidity and temperature conditions can alter the conditions of a flexible product like rubber.
Trelleborg’s dimensional tolerance standards for its laminated products, when no special manufacturing tolerances are applied, are as follows:
| Length: |
±5% (for rolls from 5 to 20 meters long) |
| Width: |
±2% (for standard widths 1.400/.1500 mm) |
| Thickness: |
