Vacuum Forming Machine

It is not very often I find myself in the position to collaborate on extracurricular creative endeavors. When the chance presents itself to do so I generally jump on the opportunity. With Halloween around the corner a crazy talented friend of mine has decided to create a custom made costume for his daughter. Only one thing stood in his way, the ability vacuum form plastic sheets over his solid sculpted costume parts.


After doing a little research on the subject and deciding on the size of the apparatus I went to work. I made a wooden box using scrap wood from around the workshop. The box has a hole cut on two sides for the insertion of vacuum hoses. The vacuumed air is pulled through perforations in the top of the box where the sculpted costume pieces are placed.


A separate wooden frame holds a sheet of plastic which is put in the oven. The heat softens the plastic and a soft belly is formed thanks to gravity. The soft plastic in the frame is removed from the oven and positioned over the vacuum form box while the vacuums are running. Vacuum action sucks the soft plastic down and around the items placed on the perforated surface. When we tested the apparatus it worked wonderfully. With my portion of the project complete I look forward to see the completed creation of my friend.
