27) Trim the mould so that the prosthetic socket and the footplate can be reinserted and are held
firmly in place.
28) Deburr and clean the mould.
Preparing the prosthetic socket and the footplate for gluing (photos see 646T113*, Sec­
tion 3.4.2)
1) Use a band saw to cut the glued joint.
2) Cut within the 3 mm gap between the prosthetic socket and footplate in order to avoid dam­
age.
3) Completely remove the putty from the prosthetic socket.
4) Avoid grinding the resin of the laminate as far as possible during this process, so that fibre
exposure is minimised.
5) Remove the putty from the footplate by grinding.
Avoid grinding or damaging the epoxy facing and the carbon.
6) If fibres are exposed during grinding or too much acrylic resin has been removed from the
acrylic resin prosthetic socket, clean the affected area thoroughly and then apply a thin coat­
ing of sealing resin.
Allow the material to dry fully for at least 24 h prior to further processing.
7) If too much epoxy resin has been removed from the epoxy resin prosthetic socket or the foot­
plate, or if fibres are exposed, clean the affected area thoroughly and then apply a thin coating
of epoxy resin.
Allow the material to dry fully for at least 24 h prior to further processing.
8) CAUTION! Only for acrylic resin prosthetic sockets, use the primer as a bonding
agent.
NOTICE! Shake the container with the primer thoroughly so that all components that
may have settled are dissolved and mixed.
9) Clean the prosthetic socket with isopropyl alcohol and allow it to dry.
10) CAUTION! Risk of falling – Do not apply the primer to the Chopart footplate and an
epoxy resin prosthetic socket, as the polyurethane bond will not be durable enough
and will break.
Apply a thin coat of primer to the acrylic resin prosthetic socket on the surfaces being glued.
11) The primer has to dry for 15 ‑ 20 min before gluing.
12) Cut a piece (approx. 1/4) from the rubber ring.
13) Clean the mould with isopropyl alcohol.
14) Roughen the footplate with the sandpaper.
15) Clean the footplate and sides with isopropyl alcohol in the area being glued, and do not touch
it again.
16) Insert the footplate in the mould.
17) Insert the prosthetic socket into the mould without touching the areas being glued.
18) Push the piece of the rubber ring under the centre of the prosthetic socket using a clean stir
stick.
INFORMATION: This ensures that the original 3 mm gap is maintained between the
footplate and the prosthetic socket.
19) Secure the position of the prosthetic socket relative to the footplate in the mould using adhes­
ive tape.
20) Clamp the assembled components facing down at an angle of approximately 45°, with the
dorsal area (toes) pointing up.
Casting the polyurethane (photos see 646T113*, Section 3.4.3)
1) Add the entire contents of component B to the container with component A. Slowly and thor­
oughly stir the polyurethane to mix it (2 – 3 min).
2) Trapped air bubbles must be avoided.
