METAPOR Breathable Mold Materials for Thermoforming and
Vacuum Forming
-
METAPOR micro-porous, air-permeable
aluminum delivers advanced solutions for many thermoforming
applications
-
METAPOR eliminates the need to
drill vacuum holes, expanding technical capabilities
of the thermoforming process at a lower cost.
-
METAPOR material has consistent
porosity which offers unparalleled design flexibility
and new ways to optimize performance of thermoform
tooling.

METAPOR Advantages and Applications
| Unlimited Design Intricacy |
 |
Highly detailed molds,
engraved inserts, and other intricate features are quickly
produced with METAPOR, since there is no need to drill
vacuum holes. |
| High Definition & Accuracy |
 |
Even porosity on all
surfaces of METAPOR results in extremely sharp definition
and accuracy of formed components without deformation. |
| Flat Surfaces |
 |
METAPOR is often used
for large flat surfaces and bottom inserts to eliminate
trapped air and related waviness. |
| Surface Quality |
 |
Absence of drilled
vacuum holes, eliminates surface imperfections on transparent
and highly cosmetic parts. |
| Faster Air Evacuation |
 |
Rapid and even air
evacuation assures that the plastic remains within its
temperature formability window resulting in reduction
of stress and better mechanical properties. |
| Prototype & Production Tooling |
 |
Quick prototype tooling
with METAPOR accelerates product development and minimizes
costly production problems. for high production applications,
METAPOR cavities & inserts are often used in conjunction
with water-cooled aluminum bases. |

| Machinability |
 |
The machining properties
of METAPOR are similar to hard wood, so it machines
faster than aluminum using standard milling machines
or routers. METAPOR must be machined without any coolants
using sharp carbide or high speed steel (HSS) tools. |
| Availability |
 |
METAPOR is sold in
slabs of 500mm X 500mm with thickness ranging from 10mm
to 400mm. Slab sizes larger than 500mm X 500mm are available
upon request. |
| Adhesive System for METAPOR |
 |
Plates larger than 500mm
X 500mm are easily constructed by joining multiple slabs
or METAPOR together using Ciba Araldite 2014 heat and
chemical resistant adhesive.
The adhesive is also used to attach METAPOR inserts
to aluminum, as well as to combine "left-over"
pieces of METAPOR in order to minimize waste.
For large and deep draw molds, hollow constructions
are created by assembling multiple plates together.
