Fabrication of the post coping:
Soldering Technique
| The coping after casting and finishing (FIG
1). Use the (RE)
P4 mandrel for positioning the base ring. Thread the Pallax base ring onto the
mandrel (FIG 2). Reduce the cast coping to 0.3mm. Position the base ring in direct
contact with the post coping. The base ring will be surrounded with solder (FIG
3). |
| Parallel the base rings and secure with sticky wax (FIG
4).
The RE H4 and H4 soldering accessories for base rings
(FIG 5). Apply
liquid colloidal
graphite, or anti flux, to the threaded areas to assure easy removal
after soldering.
Maintain horizontal position during investing to assure a proper flow of solder
(FIG 6). |
| Boil out after 45 minutes setting time (FIG
7). Ceka Sol is
recommended for soldering (FIG
8). Do not use any anti flux, as Ceka Sol contains its own
flux. Evenly apply the solder. Slightly heat the soldering accessory for
easier removal (FIG 9). |
