5.1 Fabricating the prosthetic socket
INFORMATION
The layup described in this document was approved for the maxim­
um product user body weight. The prosthetist assumes full respons­
ibility for any change to the layup.
5.1.1 Preparing for socket fabrication
> Required tools and materials:
6A43 Lamination Adapter, 501T28=M6X8 Cap Screws, Vacuum
forming dummy, 503S3 Screw, 633W8 Wax, 636K8=* Plastaband
1) Isolate the cap screws (thread and head from the outside) with
wax.
2) Screw the cap screws into the lamination adapter (see fig. 2).
3) Fill the heads of the cap screws with Plastaband (see fig. 3).
4) Position the lamination adapter on the plaster positive along the
longitudinal axis of the residual limb.

Reference 5) Place the vacuum forming dummy into the round opening of the
number lamination adapter and secure the two parts to the plaster positive
with the flat head screw (see fig. 4).

6) Isolate the head of the flat head screw with Plastaband.
501T28=M6X8
7) If there is an undercut between the lamination adapter and
plaster positive: Fill the undercut with wet plaster.
5.1.2 Fabricating a Check Socket
> Required tools and materials:
755T4=360 Outer Ring, 755X104=360 Vacuum Tube (with vacu­
um sealing ring), 755E9 Vacuum Pump, 756D2, 756B12=* or
756B20=* Oscillating Saw, 616T52=* ThermoLyn rigid or
616T83=* ThermoLyn clear, string
1) Prepare for fabrication of the prosthetic socket (see page 14).
2) Position two pieces of string crosswise on the lamination adapter
(see fig. 5). The pieces of string form air channels that make it
easier to mould the vacuum forming material to the contours.
3) Complete the vacuum forming process with ThermoLyn.
4) Finish the prosthetic socket (see page 16).
5.1.3 Laminating the transtibial socket
> Required tools and materials:
99B81=70X19X5 and 99B81=100X19X5 PVA Bag, 623T3=8 or
623T3=10 Perlon Stockinette, 81A1=8 or 81A1=10 Tube Sock,
616B1=25x* Carbon Fibre Cloth Strap, 616G2 Carbon UD Hose,
616G15 Carbon Fibre Woven Hose, 617H119 Orthocryl Lamina­
tion Resin 80:20 PRO, string
1) Prepare for fabrication of the prosthetic socket (see page 14).
2) Soak the shorter PVA bag and pull it over the plaster positive.
3) Pull a tube sock over the plaster positive.
4) Place a layer of carbon fibre cloth strap circularly around the MPT
(middle patellar tendon) point (see fig. 6).
5) Position a layer of carbon fibre cloth strap medially and laterally
from the shuttle lock up to the condyles (see fig. 7).
