Custom Design Perforating Brochure

When you have an application where a standard perforated sheet or pattern is not suitable, H&K offers custom design perforating.

There’s virtually no limit to the designs H&K can perforate for you – curved patterns, parts with irregular hole spacing, intermittent solid areas, decorative effects and much more. H&K will work with you to produce the proper tooling to fit your needs. Even if your design is non-standard, in most cases, we could use one of our many existing dies and make a few minor changes to give you the pattern you need.
