Custom Window Die For Aluminum Profile Slot And Hole Punching

The window die fits a pneumatic punching machine common in window workshops. The aluminum profile slides into the matching die channel until it hits a stop. When activated, multiple punches cut through the profile walls in one hit. This multi-punch arrangement replaces several separate drilling or milling steps, saving a lot of handling time.

Punches are made from shock-resistant steel because many profiles have internal walls that cause impact loading. Wear strips in the guide blocks maintain accurate punch alignment over thousands of cycles. An air blow system clears small aluminum chips from the die face, which prevents jamming and keeps the punching rhythm steady.

This window die can be customized for casement, sliding, and tilt-turn frame series. It is compact, easy to mount, and built for daily high-volume use. Sharpening punch tips and inserts can often be done in the fabricator's own tool room, which minimizes wait times. It supports growing window businesses that need reliable hole accuracy with low maintenance.
