ALWA TECHNISCHE PRODUKTE FÜR KUNSTSTOFFVERARBEITUNG, MODELL UND FORMBAU GMBH

The patented casting resin system ALWA MOULD D consists of two resin components and an aluminium filler. The fast curing of the material allows to produce your own technologically highest quality moulds in just a few hours. As our material is very good castable, compact moulds of any desired volume can be made from our product, such as acrylic baths, boats, etc. (<1 kg – 2500 kg). In comparison to other materials (e.g., glass fibre reinforced plastic), the system is more temperature-resistant, allows castings without air bubbles and does not have to be post-cured. Furthermore, the finished mould is easy machinable (e.g., drilling, milling, grinding, planning, sawing, turning, etc.). ALWA MOULD D moulds can be modified with repair filler, so that a fresh view can be created at an early stage of a new design process and prototypes can be examined at short notice.

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

Our patented material is highly suitable to produce foam moulds and RTM pressure injection moulds. Advantages: • Large volumes of more than 2500 kg can be cast in less than 45 min. • Good castability • Hardly measurable linear shrinkage • High temperature resistance • Demoulding process after approx. 90 min. (after adding the last backfilling compound) • Chemical adhesion to polyester or vinylester gelcoat • Immediately after the first mould half has cooled down, the second mould half can be prepared • Copper pipes keep the mould surface on a nearly constant temperature • Post-curing is not necessary ALWA MOULD D backfilling compounds are the fastest system on the market. For the surface you can chose between two gelcoats: 1) ALWA MOULD COAT This is a vinylester gelcoat that is especially suitable for high-end surfaces. It can be polished to high-gloss. 2) ALWA EPF 10 This is an epoxy gelcoat that is easy-to-use and is recommended for parts, where high-gloss surfaces are not needed

ALWA MOULD P is a cold curing casting resin for the production of porous moulds, slabs and blocks for the ceramic industry. It is a porous and high-strength plastic, which is well-suited for high pressure casting applications. ALWA MOULD P can be used in various areas of the tableware and sanitary ceramics, technical ceramics, plastic mould procedure as well as various filtration processes. The high stability and defined porosity of the material allows highly accurate mould surface reproductions. With ALWA MOULD P various geometric moulds for filtration processes of suspensions can be produced. ALWA MOULD P can be used for ceramic slip pressure casting procedures. In this procedure, water is removed by a filtration process of a clay suspension (slip), so that an increasing clay layer is built on the mould wall over time. The moulds, slabs and blocks of ALWA MOULD P are easily machinable (e.g., drilling, milling).
