Lesson 04: 6 September 2018

Vacuum Forming heats and blows up plastic sheet, stretching out the surface before moulded via vacuum air suction. It is commonly used for product packagings and turnpike signs.

Vacuum machine has to be heated up 20 minutes in advance. Place mold object on the table at the bottom, insert PVC sheet in between the clamps.

Vacuum edges will look wrinkly if suction is not done quickly.
