Laminating the Prosthetic Socket
Required materials:
>
640Z5* Plaster Insulating Cream, 623T3* Perlon Stockinette, 616G13* Woven Fibreglass
Stockinette, 616G12* Carbon Fibre Cloth, 617H19* Orthocryl Lamination Resin, 617H17*

1) Apply plaster insulating cream to the plaster positive.
2) Cut a piece of Perlon stockinette to twice the length of the plaster positive and pull on one
half.
3) Twist the Perlon stockinette on the distal end and pull on the other half.
4) Cut a piece of woven fibreglass stockinette to the corresponding length and pull on the length
equal to two-thirds of the prosthetic socket.
5) Tie off the woven fibreglass stockinette on the distal end and pull on the length equal to half
the prosthetic socket.
6) INFORMATION: For stability, a different alignment of the carbon fibres and an overlap
of 3 cm to the edge of the lamination anchor are important.
Cut two pieces of carbon fibre cloth to size as a mat according to the edge of the lamination
anchor.
