ALWA ALUMINIUM BLOCK (resin-based) is made for the thermoforming process (e.g., polystyrene, polycarbonate, acryl, etc.).
ALWA ALUMINIUM-BLOCK (resin-based) is characterized by the following advantages:
- Good mechanical finishing
- High temperature resistance
Moulds made of ALWA ALUMINIUM-BLOCK are resistant to temperatures of up to 135 °C, short term exposure of up to 180 °C is possible, taking into account the lower compressive strength of the mould due to the temperature.
