Product information "ALWA MOULD D System"
ALWA MOULD D System
The casting resin system consists of two acrylic resin components and a filler.

The rapid curing of the material allows the production of high quality moulds in just one day. The material is very easy to cast, so moulds of any size can be produced, such as bathtubs, boats, etc. (<1 kg - 2500 kg).

Compared to other materials (e.g. glass fiber reinforced plastic), the system is more temperature resistant, allows potting without air bubbles and does not require post-curing. In addition, the moulds can be machined (2. e. drilling, milling, grinding, planing, sawing, turning, etc.).

ALWA MOULD D moulds can be modified with repair putty so that appropriate views can be created at an early stage of a new design process and prototypes can be examined at short notice.
Application: Bath tubs, shower trays, Vacuum thermoforming

All advantages at a glance

ALWA MOULD D molds Are suitable up to a temperature range of 135 °C, short-time loads up to 180 °C Are possible taking into account the lower compressive strength of the mold due to the temperature. To control the temperature of the mold during the production process, copper tubes or heating elements can be fixed to the model.

To ensure an equal coefficient of thermal expansion, only aluminum parts and aluminum perforated plates should be fixed in the casting box as reinforcing material and then encapsulated with casting resin. Steel wires with silicone tubing can be fixed in the model, eliminating the need for time-consuming vacuum drilling on the mold.
