Porous - Import export

Together with the Fachhochschule Münster – University of Applied Sciences we are working on ALWA PERM (patent No. 2583995). This is a metal-filled casting resin for producing a porous, resin-bound mould. These materials are applicable in the areas of thermoforming, the ceramic industry, intake moulds and devices, pneumatic cushioning, the filter industry, etc. ALWA PERM allows a castable production of porous metallic materials with a binder for the first time. The system offers a highly accurate mould surface reproduction. The profile characteristics goes far beyond the current state of the art. NO MORE DRILLING OF VACUUM HOLES! NO DAMAGE OF THE MOULD SURFACE DUE TO DRILLING HOLES

ALWA POR is porous and has a smooth surface structure. The product is characterized by a high stability, pressure-resistance and a long-term heat resistance of over 190°C. It is especially suitable for moulds with fine and complex structures. The good air permeability leads to a uniform stretching of the foil in the process of thermoforming. With this innovative product the annoying drilling of vacuum holes becomes obsolete and thus no visible markings are left on the thermoformed foil. Larger dimensions can be achieved by screw connections. Longer and wider dimensions by gluing. ALWA POR is easily machinable: Sawing, drilling, grinding, polishing. It also remains porous after polishing. ALWA POR is especially suitable for vacuum thermoforming and vacuum forming and is additionally suitable for - aeration of aquaria, fishponds and sewage treatment plants, - venting of injection moulds and blow moulds, - any proceedings of hot steam or water steam processing, - vacuum clamping

This stainless steel anchorage point (Ø 16 mm) was specially developed with a larger base plate (370 x 370 mm) for installation in lightweight or porous concrete. The 8 anchor rods supplied in the package are cemented permanently into the concrete substructure using special adhesive.
