Profile Grinding Challenges in Connector Progressive Dies
In modern connector manufacturing, progressive stamping dies often operate at extremely high speeds — commonly 200 to 400 strokes per minute. At these speeds, punch performance becomes a critical factor in maintaining…
Case Study: Improving Punch Life at 280 SPM Through Edge Radius Control
At high stamping speeds, punch failure is rarely caused by dimension error alone. In this case study, we share how controlled edge radius — not tighter tolerance — improved punch life significantly…
High-Speed Stamping Tool Wear: Why Force Balance and Precision Profile Grinding Matter at 300+ SPM
At low stroke rates, stamping can appear deceptively simple: sheet metal, a tool set, and a press.But once production moves into 300+ strokes per minute, the process stops behaving like a static…
Tungsten Carbide Punches vs Tool Steel Punches
In precision metal stamping, punch materials impact tool life, stamping stability, maintenance cost and overall production efficiency. Tungsten carbide punches and tool steel punches are widely used. In this article, we will…
Why Punches Fail at the Edge — Not Just the Dimension
This results in stable edge conditions, reduced local stress concentration, and improved contact behavior during stamping. For punch inserts with intricate shapes or tight internal radii, PG offers a level of control…
WEDM vs PG Grinding for Stamping Dies: How to Choose the Right Process
In the stamping die industry, machining accuracy is not only about dimensions, but also cutting performance, punch life, and production stability. Therefore, choose the right process between WEDM and PG grinding for stamping dies can…
How to Achieve Perfect Parallelism on Mold Inserts
In precision mold manufacturing, it’s very critical to achieve perfect perfect parallelism on mold inserts. Even a minor deviation in mold insert parallelism can lead to uneven wear, flashing, unstable part quality, and…
PG Grinding vs EDM, Which One Is Better?
In mold and die manufacturing, PG grinding vs EDM are both widely used processes for producing precision punches, inserts, and tooling components. As each method has its own strengths, selecting the correct…
Why PG Grinding Is Critical for High-Precision Punches and Inserts
Today, the demand for higher precision, stable assembly and longer tool life continues to increase. The demand brings a great challenges for mold and stamping die manufacturing. As core functional components of…
