Why Choose PG Inserts?

Accurate fitting reduces assembly adjustments
Stable repeatability for replacement inserts
Controlled dimensions and surface finish

Hepha Precision produce every insert according to customer drawings or sample. We use PG grinding to ensure profile accuracy, surface quality and dimensional stability. Therefore, the inserts not only fits reliably in mold or die assemblies, but also provides stable repeatability for replacement inserts. Downtime reduced and production efficiency improved.
