ALWA MOULD D - Casting resin for the thermoforming process

In the following “ALWA MOULD D” (patent no. 2801463).

ALWA MOULD D consists of two resin components and an aluminium filler. The fast curing of the material allows to produce technologically highest quality moulds in just one day. 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 / Porous blocks and slabs

ALWA POR ALUMINIUM is a porous slab made of aluminum and a binder. With this innovative product the annoying drilling of vacuum holes is eliminated and thus you get crystal clear thermoforming sheets.

The product ALWA POR is characterized by high stability, pressure resistance and a long-term temperature resistance of over 190 ° C and is particularly suitable for forms with filigree, complex structures.

ALWA POR ALUMINIUM is particularly suitable for thermoforming and other vacuum processing, and is also suitable for
  • hot steam or water steam processing (EPS/EPE/EPP),
  • vacuum clamping and gripper technology,
  • filter applications,
  • air film sliding technology,
  • aeration of aquaria, fish ponds and sewage treatment plants,
  • foundry and many other applications.
ALWA POR MINERAL is suitable for vacuum clamping technology, filter applications, aeration of aquaria, fish ponds and sewage treatment plants, air film sliding technology and many other applications. The material has a long-term temperature resistance (mould temperature) of approx. 130 °C.

ALWA POR STEEL is suitable for injection moulds and blow moulds venting and, therefore, is an economic alternative to expensive sinter plates. The material has a long-term temperature resistance (mould temperature) of approx. 190 °C.

ALWA POR PLASTIC is suitable for vacuum clamping technology, filter applications, aeration of sewage treatment plants, air film and sliding technology and many other applications. The material has a long-term temperature resistance (mould temperature) of approx. 65 °C. The average pore diameter is flexibly adjustable from approx. 8 µ to 23 µ.

We would gladly send you a sample of our new material. If you are interested, please contact Mrs. Thomas (n.thomas@alwa.de)  with reference to the desired version (ALUMINIUM, MINERAL, PLASTIC, STEEL), she will be happy to help you.

Our entire product range can be found on our website www.alwa.de.

Our reference customers in the chocolate, display and dental industry have already made excellent experiences with our new product ALWA POR and we are looking forward to welcoming you soon as our customer as well.

Please do not hesitate to contact us if you have any further questions.

ALWA MOULD D Backfilling Compound for RTM Pressure Injections / Foam Moulds

ALWA MOULD D backfilling compounds are the fastest system on the market.

Our backfilling compounds for compact moulds are suitable for RTM pressure injections and foam 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 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

Backfilling compound (lean mixture)
You can choose between two backfilling compounds:
-          mineral backfilling compound
-          aluminium backfilling compound

Generally, the cost-effective mineral backfilling compound is chosen for RTM moulds, while for foam moulds either a mineral backfilling compound or an aluminium backfilling compound is used depending on the application. The advantage of an aluminium backfilling compound over a mineral backfilling compound is the better thermal conductivity. Moreover, the mould made of an aluminium backfilling can be machined very well. In order to strengthen the mould made of an aluminium backfilling compound, only aluminium perforated sheets  (2 – 3 mm) should be used.
