Membrane Press Forming

Membrane press forming may be considered a type of “drape” forming, however this process requires the use of a vacuum. In our case, we heat a sheet of material, drape it over a mold which is usually made of wood, epoxy, or aluminum and then a vacuum is pulled between the mold, which has the material and the membrane on it. As the vacuum is pulled, the membrane is able to push the material in the configuration of the mold.

Membrane Press Forming in Action

1

Pliability

Material is being heated in an oven to it’s specific forming temperature, also known as pliability.

2

Press

The heated material is then transferred and pressed onto the tool, which forms to the shape of that specific tool.
