Engineering Standard 2.0
Precision in Motion
The Triple-Action Fine-Blanking process allows us to achieve 100% sheared surfaces without tearing.
The Triple-Action Difference
FIG 1.2: SHEARED SURFACE FINISH
01
V-Ring Clamping
The unique V-Ring bites into the material before shearing begins, locking it in place to prevent material flow and tearing.
02
Controlled Shearing
Punch and counter-punch work simultaneously with precise clearance (0.5% of thickness), shearing the metal smoothly instead of breaking it.
03
Active Ejection
The part is ejected counter-pressure, ensuring flatness is maintained throughout the cycle.
