This sequence of images shows the process of pressure moulding:
Prepare Model
First a diagnostic wax-up is prepared and this will be the base from which an impression is taken and a working model is cast.
Material Selection
A thermoform foil (or blank as it is known) is selected with the required thickness.
Place Foil
Using a Scheu-Dental Biostar, a thermoform foil (or blank) is inserted into the pressure chamber and clamped tight.
Place Model
The working model is placed on its platform.
Heat Foil
An infra-red heater heats the foil to its working temperature, the heater is removed, and the pressure chamber (with foil) is closed down over the model and clamped down tight.
Apply Air Pressure
Pressurized air is blown down over the foil to further distribute the thermoform material over the surface of the working model.
Remove Stent
The pressure is released and the model and stent are removed from the equipment.
