5.1 Fabricating the thermoplastic socket

A prosthetic socket made of thermoplastic synthetic material is fabricated either as a check sock­
et or the inner layer of the definitive socket, sealing the definitive socket. The difference between
the two prosthetic sockets is the choice of material.
Required materials: 616T283* ThermoLyn clear or 616T252* ThermoLyn rigid for a check
>
socket, 616T183* ThermoLyn PETG clear for a definitive socket, wet sanding paper, degreas­
ing cleaner (such as 634A58 isopropyl alcohol)
1) Vacuum form the prosthetic socket using thermoplastic synthetic material.
2) Check socket only: Roughen the distal end of the prosthetic socket from the outside with
wet sanding paper.
3) Definitive socket only: Roughen the entire prosthetic socket from the outside with wet sand­
ing paper.
4) Degrease the outside of the prosthetic socket.
5) Glue the lamination disc to the prosthetic socket (see Page 18).
