METAPOR© - Breathable mould material for thermoforming and vacuum clamping applications

Some description

METAPOR© is a micro-porous, air-permeable aluminium. METAPOR© can be used with advantages in the thermoforming industry as well as for vacuum clamping and air cushion devices.

For thermoforming the advantages are numerous:

The time consuming and expensive process of drilling the traditional vacuum holes lapse.
METAPOR® is often used for large flat surfaces and bottom inserts to eliminate trapped air and related waviness.
Rapid and even air evacuation assures that the plastic remains within its temperature formability window resulting in reduction of stresses and better mechanical properties.
Absence of drilled vacuum holes, eliminates surface imperfections on transparent and highly cosmetic parts.
Tools inserts with engraving or other fine details can be produced very quickly, because vacuum-holes avoided and quality of the fine details of the vacuum-formed parts are much higher.
The machining of METAPOR© block material is faster than "tool aluminum", and blocks can be easily bonded together with example Araldite 2014, which is a heat and chemical resistant filled epoxy, which together with the vacuum holes avoided, enabling very fast and flexible to produce good prototyping tools.
