I am looking for some information on preform materials for Cad/Cam
systems. Our centre has recently acquired the Seattle Shapemaker
System and my I'm interest lies in finding out what preform material
other centres are using for their Cad/Cam system. Currently we use K.
Resin preforms for check sockets and Duralene preforms for definitive
sockets. The main problem with K. Resin preforms is that it's
difficult to heat and reshape once they have been moulded. With the
Duralene preforms it's not so much the duralene that's the problem but
the Pelite (polyethylene based foam) material that we use for the
liner. We have found that both the high and low density Pelite foams
tend to compress or bottom-out under the extreme heat (220 degrees
Celsius) and pressure they are subjected to in the Thermoformer. We
have already been in contact with the Seattle Limb System and they
don't offer any materials that could be used for liners. Can anyone
suggest a foam based material that would be suitable for this process.
Thanking you in advance for any suggestions.
