5.2.3 - Repeat item 5.2.2, now rotate the larger ring clockwise to the return the fixing system (04) to the normal position
and the plate to the initial position. Leave heating for a few more seconds the same side of the plate that initiated the
process.
5.2.4 - After the heating process is complete, follow the steps of the conventional process from item 5.1.9, until the
process is finished.
Attention:
Never lower the plate fixation unit set (04) when the larger ring is rotated 180º counter-clockwise direction, photo 24.
6 - SAFETY AND FUNCTIONALITY PRECAUTIONS
6.1 - A very porous plaster should be used since the air will pass through the model to provide a more efficient vacuum.
6.2 - Trim the model to avoid big deformations of the plate (20mm maximum, or use cup model holder and glass beads).
6.3 - When working with the flat part of the model holder leave the plaster model base flat to stop the blank from
penetrating the gaps between the plaster model and the model holder.
6.4 - The heating on both faces of the blank is ideal for two different types of materials and for traditional
blanks with thickness higher than or equal to 3mm.
6.4.1 - The heating system of both faces of the blanks must follow the heating process according to the characteristics
of the materials used in the manufacturing of the blanks. This information should be obtained from the blank
manufacturer.
6.4.2.1 - For traditional blank thickness equal or higher than 3mm we recommend heating in two (2) phases. First the
side of the blank that will stay in contact with the model (internal side of the blank). To do that, rotate the blank fixation
unit (04) directing this face to the heating unit (02). After this pre-heating, rotate the blank fixation unit (04) to the
original position to heat the external side of the moulder.
6.4.2.2 - For double strip blanks* that have a soft material face of low softening temperature and the other face of a
stiff material of high softening temperature, we recommend heating in three (3) phases initiating the heating from the
stiffer face, then from the softer or soft face and finally the stiffer face again until the plastic point according to item
5.1.8.1, this way the double strip blank* should be mounted on the machine with the stiffer face upwards to the heating
unit direction and, consequently, the soft face will conform the model.
6.4.3 - Due to the diversity of blanks and jobs that can be done, we suggest a careful previous analysis of the process
before starting each job .
Note*: Double Strip are blanks made from two (2) different types of materials.
Example: Blanks with one stiff face and the other soft.
