Hydraulic Punching Systems


AMRT Viper™ Rotary Punch & Cutoff System

Our VIPER™ Rotary Systems* use proprietary vertical-approach technology to the production of both lighter steel framing and heavy 10-gauge structural products. VIPER Systems require no special maintenance equipment and accept standard linear tooling for additional cost savings. Our design allows close coupling of punch & cutoff to the rollformer for increased operating speed and reduced space requirements.
