Vacuum Casting

Using a vacuum pump and a bag filled with polystyrene beads, negative and positive molds could be readily created for final socket production. Our team focuses particularly on testing different materials to make the polystyrene bag component of the system more durable. Our goal is to make very comfortable sockets from accurate molds with the cheapest and most effective materials possible.

The present Vacuum Casting System uses vacuum created about a bag containing polystyrene beads to produce the negative mold of a stump.

In addition, we aim to make the whole process more self-contained and thereby reduce the amount of plastic bags used every time. This must be done without jeopardizing the effectiveness and hygiene of the socket. Our team is working to optimize the system in an effort to reduce inefficiencies caused by the loss of vacuum around the negative and positive molds.
