Progressive Die Punch by PG Profile Grinding

PG Profile Grinding for complex punch geometry
Profile accuracy up to ±0.001 mm
Excellent edge sharpness and surface finish
Stable repeatability for replacement punches
Fully custom-made to drawings or samples
Suitable for micro and precision punches

PG punches are ideal for high-speed progressive dies, where stable performance and long tool life are critical.

Progressive Die Punch is customized according to customer drawing or samples. They allows precise control of width, profile shape, step geometry, and edge condition.

PG is able to produce micro punches with widths as small as 2–3 mm. At the same time, it maintains tight tolerances across the full length.

Typical Applications:

Progressive stamping dies
Precision metal stamping molds
Connector and terminal dies
Automotive and electronic components
High-speed stamping production lines

요점: PG는 다음 분야에서 탁월합니다. 작고 섬세하거나 벽이 얇은 부품 변형 없이.

During the manufacturing process, we apply dimensional inspection and process control. This step ensure consistency and repeatability, making sure our PG grinding punch suitables for both prototype development and repeat production. Hepha Precision support Custom designs, small batch orders, and stable lead times. Therefore, technical drawings are welcome for evaluation. What’s more, each project is handled with a tooling-oriented approach to ensure reliable performance in actual stamping applications.
