14) Cut off a piece of carbon fibre woven hose (1.3 times the length of the
plaster model).
15) Pull the carbon fibre woven hose over the plaster model to the edge (see
fig. 18).
16) Tie off the excess carbon fibre woven hose at the distal end and pull it
over the plaster model (see fig. 19).
17) Tie off the carbon fibre woven hose tight in the distal groove of the cylin­
der body.
18) Tie off the carbon fibre woven hose tight in the undercut of the cylinder
body using a perlon string.
19) Expose the valve dummy.
20) Pull a tube sock over the plaster model.
Prosthetic socket with carbon finish
1) Cut a piece of carbon UD hose (2 times the length of the plaster model).
2) Pull the carbon UD hose over the plaster model up to the edge.
3) Tie off the excess carbon UD hose at the distal end and fold it over the
plaster model.
4) Pull a tube sock over the plaster model.
5) Soak the longer PVA bag and pull it over the plaster model.
6) Perform the casting process with Orthocryl. Because of the 6 layers of
perlon stockinette, approx. 30 % more Orthocryl is needed.
7) Once the lamination resin is sufficiently distributed: Displace
excess lamination resin in the area of the cylinder body to the distal end
by wrapping with polyethylene adhesive tape. Wrap tightly so the system
becomes airtight.
8) Allow lamination resin to cure.
9) Finish the prosthetic socket (see Page 27).
Prosthetic socket without carbon finish
1) Cut a piece of carbon UD hose (1.5 times the length of the plaster mod­
el).
2) Pull the carbon UD hose over the distal half of the plaster model (see
fig. 20).
3) Tie off the excess carbon UD hose at the distal end and fold it over the
plaster model (see fig. 21).
4) Tie off the carbon UD hose in the undercut of the cylinder body (see
fig. 22).
5) Cut a piece of perlon stockinette (2 times the length of the plaster mod­
