The template (dummy) provided is inserted before vacuum forming or
laminating, making it possible to accurately install the valves into various
socket materials.

Saturate a 99B25 Nylon Sock with N-Wax=1 and pull it on the plaster positive.
Attach the 21Y157 Vacuum forming template to the plaster positive using
the 503S3 Screw provided (fig. 3).
After vacuum forming the test socket or the ThermoLyn definitive inner
socket (fig. 4), smooth the vacuum forming template by grinding it until it
is flush with the ThermoLyn material (fig. 5).
Attach the lamination dummy to the vacuum forming template using the
501T19=M5×18 Countersunk Head Screw provided (fig. 6).
For frame reinforcement, the 5Z1 Lamination Kit with the aid of the Technical
Information Booklet 2.3.5 or the 5Z4 Lamination Kit for CAT-CAM can be used.
After lamination, evenly grind off the excess lamination around the lamina-
tion dummy and remove the countersunk head screw.
Remove the socket frame and inner socket from the plaster positive.
