supports you in finding the
optimal tolerance values
Determining drawing tolerances and their compliances in plastic injection molding is our constant focus of discussion.
Thermoplastic moldings cause dimensional changes due to the materials deployed and the production processes. In view of the uncertainties of these relationships, the tolerances are often too narrow or too wide.
Cost factor tolerances
The cost of production of parts to increase substantially the closer tolerances are specified. Subject to production tolerances acceptance conditions, resulting in too tight tolerances:
- Increase of the production costs
- Increased effort in tooling and in quality assurance
- Higher reject rate
- Increase in customer complaints
