METAPOR BF 100 AL block material is available in plates 500mm x 500mm
with thickness ranging from 10mm to 400mm. This product is porous, it
machines like hard wood, and is used for both prototype and production
tooling for thermoforming. In case of production tools, METAPOR inserts
are ususally placed inside aluminum base plate with standard water
cooling system. For prototyping applications, METAPOR is often
integrated with REN board from Ciba for complex areas of the mold.
Since METAPOR is completely porous it results in extremely high
definition allowing replication of complex surface patterns, logos,
etc. For flat surfaces METAPOR eliminates trapped air that can create
waves in the plastic sheet.
ESPOR Casting Technology is available as a service for production of
cast air-permeable shapes. This is a reverse casting process, so if the
pattern is "female" the mold will be "male". This process is especially
suitable for large and deep molds as well as for molds with complex
textures such as leather grain, etc. ESPOR has ZERO shrink, so the
molds are extremely precise. Also, we often integrate conformal cooling
lines for production applications.
Both ESPOR & METAPOR are also used for vacuum clamping and air-bearing
Rapid Prototyping patterns can also be used for vacuum forming. FDM
patterns are also porous, so there is no need to drill vacuum holes.
All other types of RP patterns can be used as long as they can withstand
the temperature of the plastic sheet.
If you need additional information about these tooling materials or
about vacuum forming machines, please contact me directly.
