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

Improve device effectiveness–Design is customizable per application and can incorporate anti-static properties. request sample ask an engineer

The GESIPA® TRI-FOLD® blind rivet forms three press lashes on the closing head side during setting. The advantages The large moulded lashes distribute the exerted clamping force evenly and gently onto the riveted material. Also, the large surface of the lashes offer excellent protection against the rivet being pulled through very soft, porous or brittle application parts. Thanks to its special design, the TRI-FOLD® is also able to compensate over-dimensional or irregular drill hole diameters. Application areas TRI-FOLD® blind rivets are excellently suited for the automotive field, e.g. for plastic panelling, car body parts and for the interior work inside vehicles, but also for all other applications that are particularly soft, brittle, easily deformed or porous.

The latest generation of REA JET GK 2.0 high-resolution coding and marking systems using piezo technology is suitable for direct, high-contrast coding and marking on absorbent and porous surfaces, such as wood, cardboard and paper, with a variable print height of up to 100 mm. Applications: — Porous and absorbent surfaces: paper, cardboard boxes, wood, textiles, fleeces, building materials, polystyrene, grinding wheels etc. — Variable print data such as date, time, counter, shift code or database content — Alphanumeric texts, barcodes, data matrix codes, logos, warning notes — Coding and marking of packaging — IPPC coding and marking on pallet blocks — EPAL coding and marking of pallets — CE marking on wood — Marking of paper sacks — All-round coding and marking of fiber drums — Marking of OSB panels with logo — Coding and marking of pallet boxes — Marking of gypsum boards or board stacks with large logos — Serialization and track & trace applications

These small pellets are made of pure, binderless sintered glass, and represent a completely new substrate for use in bioreactors. The open-pored structure of approx. 40...100 µm permits microorganisms to accumulate in the cavities between the sintered glass particles. This ensures that even deeply-embedded cells are supplied with the surrounding medium. Moreover, the material's high purity and its smooth surface provide optimum conditions for high cell growth. Application areas Trickle bed reactors in sewage treatment Substrate for microorganisms and cells in bioreactors Special features Pure sintered borosilicate glass 3.3 Pore size about 40...100 µm Pellet diameter 4 mm Large surface area Optimum flow characteristics High surface charge (Zeta potential) Top-class biocompatibility Enhanced cell growth, because there is no cell agglomeration due to confinement in microcapsules. This REM image shows the open structure and the smooth surface as a result of the sintering process....
