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.

FAQs
We typically achieve ±0.002 mm tolerance with PG optical profile grinding.For simpler geometries or specific critical features, tolerance can reach to ±0.001mm. Final capability depends on part geometry, material, and profile complexity.
We typically grind radii as small as R0.02 mm (tool steel) and R0.01 mm (carbide).
All sharp corners are produced with a controlled micro-radius for durability and performance.
Yes. We specialize in complex and asymmetric PG-ground profiles, including compound curves and non-symmetrical shapes.

Yes. We regularly support connector molds and precision stamping dies, including fine-pitch and high-wear punch applications.
We accept UG,CAD,DWG files are preferred for complex PG profiles.
Normally 2-3days for production. The actual lead time will according to your design and quantity.
We have no strict MOQ, prototype & small batches are welcomed.
Customer drawings are treated as confidential, used only for production, and never shared with third parties. NDAs are available upon request.
PG optical profile grinding provides significantly higher profile accuracy and repeatability than standard grinding, especially for parts with complex contours and functional edges.
Compared with standard grinding, PG grinding offers:
Superior profile accuracy for curves, angles, and asymmetric shapes
Direct optical profile verification during grinding
Cleaner, sharper cutting edges with controlled micro-radius
Better consistency across multiple identical parts
Standard grinding is well suited for straight surfaces and simple geometries.
However, when the function of a punch or insert depends on precise contour shape, PG optical profile grinding ensures the profile matches the design intent exactly.
For precision molds, connector tooling, and fine-pitch stamping applications, PG grinding often results in more stable performance and longer tool life.
