Drilling & Punching


Many seals require ‘vent holes’ that enable the seal to collapse when pressure is applied, such as when a door closes.

The extrusion process is such that we can add drilling to the extrusion at precise, unifrom intervals as it is manufactured.


Parts, cut-to-length, are placed in a punch press where a custom designed die creates the specific hole or feature intended.

Holes are punched at precise uniform intervals, perfectly suited to seal between bolted or riveted panels, as well as to seal large rectangle flanges with uniform holes and more.
