CHEAP Vacuum Forming With Plastic Bottles




This is a cool project you can do with a vacuum former and a few milk bottles,

I will make an Instructable on how to make a former but for now look at others there are some great ones,

you can checkout how to make this with free plans here

Step 1: Gather Your Quipment

I have here a ;

  • Home made vacuum former
  • heat gun
  • toy figure(I got mine from Mc Donalds)
  • And a vacuum

Step 2: Making Stuff..

Plastic from the bottle is then stapled onto a frame.

Step 3: Vacuum Forming..

The frame is then pressed when hot from the heat gun and the vacuum is turned on ,the plastic gets pulled around and sucked down creating an object from the mould.

    What a wonderful instructable. I used what I had on hand: cut a whole in a plastic box, used a vent cover (screen over louvres) for the top/base. Worked like a charm! Since I don't have a heat gun, I popped the plastic (in the wood frame) into a toaster oven at 450 until the bottle plastic became clear and started drooping. I've also substituted cheap, thin plastic cutting boards from the dollar store. Works well.

    If this plastic is food-grade to start with, would it still be food grade after heating it to reshape it or would it be a bad idea to use with food?
    This would be a great way to make your own unique candy/chocolate molds but I wouldn't want to make anyone sick.

    Have a look here:

    I think the main problem with this (vacuum forming) is that there may be bacteria etc. on the plastic from the previous product, handling, contact with the former (toy from McDonalds?) etc. So you'll have to be careful but I guess you would wash whatever you made before anything edible. Just make sure you don't try to sell anything made using these moulds, you should be OK :)

    Oh, by the way, don't try washing your formed shapes in the dishwasher, they'll end up as flat plastic again!!
