Clean-Edge® Blanking +/-

Clean-Edge® Blanking is the process of stamping high-tensile, pre-tempered material to create a maximum edge condition with minimal shear and controlled breakage. This process reduces stress risers on the blanked edge, thus highly increasing fatigue life.

Process Advantages of Clean-Edge® Blanking

This process results in lowest number of fatigue failure initiation sites, which is essential for long-term, consistent performance of stamped parts. It also:

Minimizes residual tensile stress
Decreases burr occurrences
Controls edge condition

Our Tooling Research and Design Produces Optimal Performance Standards:

Proprietary design based on in-depth research
In-house tooling for superior customer service
High-performance progressive and compound carbide dies
Proprietary surface finish requirements for cutting components
Die clearance adjustable to within .0025mm

ISO Finishing™ +/-

ISO = All things equal (from Greek word isos). Superior surface finish = ISO-Finishing™.

Equal on both sides of component
Equal from piece #1 to piece #1,000,000+
Engineering-approved process covering all aspects of finishing

Surface Finish Advantages:

Creates finished surface as smooth as .25 Rz maximum
Induces light magnitude of residual compressive stresses for increased fatigue life
Random matte finish reduces surface imperfections

Edge Radius Advantages:

Eliminates stress-concentrating notches/burrs
Symmetrically finishes edge to remove stamping distortions
Removes tensile stress from blanking operations
Controls process to prevent over-finishing
