Drilled aluminium honeycomb

Perforated aluminium honeycomb is normally used as core for vacuum tables and as core for moulds in the wind blade industry. The honeycomb is normally perforated longitudinally to permit the correct air flow.

Perforations are implemented in compliance with our customers’ needs although 6 hole-perforation is standard.
