A Step-by-Step Guide to Moulding a Flexible Prosthetic Socket
Pull the perfect prosthetic sockets
The soft and supple Orfitrans thermoplastic sheets are ideal for the fabrication of flexible prosthetic sockets and can be used as a comfortable lining material.
In this guide, we explain how to expertly mould our flexible thermoplastic sheets for smooth and soft sockets. We show how to prepare the sheet, optimize your positive mould and share some general moulding tips.
Follow the steps and pull the perfect sockets time and time again.
Remove the protective film on both sides of the sheet.
As an optional step, you can cut the sheet to the shape of the supporting frame. The excessive material could otherwise get in the way during the moulding process.
Wedge your thermoplastic sheet firmly into the supporting frame.
4. Position the positive mould:
Pull a piece of stockinette over the base of the positive mould to aid in the removal of the socket later. Just make sure it does not cover the actual socket area, this will result in a rough inner surface.
Position the positive mould on the vacuum pump. You can lightly spray the mould with a silicone de-moulding spray to aid in the socket removal afterwards. Note: silicone de-moulding spray can be used for all Orfitrans sheets, except Orfitrans Excel.
Look at the long and short edges of your positive mould and picture how you will be placing the bubble. Make sure you have enough material to cover the long side of the mould.
