METAPOR®: Breathable Mould Material for Thermo- and Vacuum Forming
METAPOR® micro-porous, air-permeable aluminium delivers advanced solutions for many thermo forming applications:
- METAPOR® eliminates the need to drill vacuum holes, expanding technical capabilities of the thermoforming process at a lower cost.
- METAPOR® will leave NO markings on your parts compared with “traditional” aluminium tools (with drilled holes).
- METAPOR® offers to manufacture Moulds faster (2-3 times faster machinable than aluminium).
- METAPOR® allows fast cycle times due to significantly enhanced (entire surface) air and temperature evacuation.
- METAPOR® material has a very consistent porosity which offers design flexibility by eliminating the need to engineer and manufacture complex venting systems.
High Definition & Accuracy
Fine and structured surfaces are possible to produce. Same material wall thickness, no air inclusions and no stretching of the foil results in high-definition thermoformed parts.
Faster Air Evacuation
Due to it’s air-permeability all over the whole structure. Rapid and even air evacuation assures that the plastic remains within its temperature formability window resulting in reduction of stresses and better mechanical properties.
Unlimited Design Intricacy
Highly detailed moulds, structured surfaces, engraved inserts, and other intricate features are quickly produced with METAPOR®, since there is no need to drill vacuum holes.
Crystal clear transparent parts
Vacuum forming of transparent material can be processed with METAPOR® moulds without markings & striations.
Extreme deep thermoforming’s with sharp edges that are accurate in every detail are possible.
Ideal for flat and large Surfaces
METAPOR® is often used for large flat surfaces and bottom inserts to eliminate trapped air and related waviness .
Large volume Thermoforming moulds
For high production applications, METAPOR® as cavities & inserts are often used in conjunction with water-cooled aluminium bases.
