Tamau helps the customer in design development. We ensure the feasibility of the project suggesting engeneering amendments suitable for the foundry mass production.
These are few suggestions:
Eliminate angles < 0.8.
Deter material thicknesses less than 2 mm (this is in order to make the injection easier and to reduce deflection).
Avoid sudden section variations
Harden surfaces as more as possible so to reduce deflection risk.
Detail/emboss a wide selection of Identification Markings.

In some cases it is necessary to use oversizes, for the more restricted tolerances:
