EPS / EPP tools

Material performance

The new technology of permeable mold's components has been developed.  Now it is possible to decrease energy  and labor  costs on production  and exploitation  of molding equipment in EPS and expandable thermoplastic  production.

It is a very perspective side of ALUPOR™.

EPS / EPP molds made of ALUPOR™ ensure  economy 30% of cycle time and 40% of mold weight

We are ready to make pre-machining or even finish mechanical treatment of the molds and its components. 

Avalible machining equipment:

 

Theere is also the offer for traditional molds users - vents made of ALUPOR™ 100-200 with fine porous structure. Such vents can improve surface quality of EPS / EPP part in vent area. Perforated vents has min 0.3 mm size when ALUPOR™ 100-200 ones has max 0.2 mm pore size.
