Non-Standard Tungsten Carbide Punch – PG Profile Grinding Precision

Key Features of Non-Standard Punch

Product Description of Non-Standard Punch

Hepha Non-Standard Punches, mainly precision-manufactured by PG Profile Grinding. They are specially designed for complex and customized stamping requirements where standard punches are not suitable.

Made from tungsten carbide, these punches offer exceptional hardness, wear resistance, and dimensional stability, making them ideal for high-volume and high-speed stamping operations. PG profile grinding allows precise control of punch geometry, including stepped profiles, tapered sections, and sharp or controlled-radius cutting edges.

Unlike conventional machining methods, PG grinding ensures superior profile accuracy and surface consistency, especially for non-standard shapes and micro punch features. This process enables us to achieve tight tolerances and excellent repeatability, which is critical for die assembly accuracy and replacement punch compatibility.

Each precision punch is custom-made according to customer drawings or samples, with full control over dimensions, profile angles, edge condition, and overall length. Whether used in progressive dies, fine blanking tools, or precision metal stamping molds, our tungsten carbide punches help improve tool life, reduce downtime, and maintain consistent part quality.

With strict inspection using optical profile measurement systems, we ensure every punch meets the required specifications before delivery.
