PETG (Polyethylene terephthalate) is a transparent thermoform plastic that offers cost-effective vacuum formed parts with deep draws and precise details. PETG is significantly less prone to cracking than acrylic (Plexiglas). It is used for vacuum forming all kinds of clear plastic parts - especially blister and clamshell packaging and point-of-purchase retail displays. PETG is also FDA food safe and is commonly used to make molds and other kitchen products. See our Common Thermoform Plastic Questions & Answers Section below for more details.

How To Vacuum Form Plastic At Home in 3 Easy Steps
  1. STEP 1: Secure your thermoform plastic between the Hobby Vacuum Former's metal clamping frames with the provided spring clips. Attach your Shop-Vac (not included) to the vacuum former. Place your model on top of the vacuum formers perforated aluminum platen.
  2. STEP 2: Place the thermoform plastic in your kitchen oven and watch as it begins to sag. When the plastic becomes soft, remove it from the oven. Align the metal clamping frames with the Hobby Vacuum Former's guides and lower the plastic over your model.
  3. STEP 3: The hot thermoform plastic forms an air tight seal around the edges of the aluminum vacuum platen. Vacuum pressure pulls the hot plastic down around the model. After cooling for a few seconds the thermoform plastic part hardens and is ready to be removed.

Common Thermoform Plastic Questions & Answers

What Kinds of Plastic Can You Vacuum Form?

What Else Do You Need To Get Started Vacuum Forming?
  • Hobby Vacuum Former made by WidgetWorks Unlimited LLC.
  • Kitchen oven
  • Shop-Vac style vacuum cleaner with 1 1/4" hose (or larger vacuum with 1 1/4" adapter)
  • Leather gloves to protect your hands while holding the hot plastic / metal clamping frames
  • Model or mold to form the hot plastic around

Will Your Kitchen Oven Work With Our Thermoform Plastic Sheets?
  • Thermoform plastics become soft and formable when heated to 250-350 F. Most kitchen ovens are perfectly suited for the job. Both electric and gas ovens can be used with good results. If you have an "efficiency" kitchen or live outside the USA, we recommend that you measure the inside of your oven to verify that the plastic sheets can fit inside.

Will Your Shop-Vac Vacuum Work With Our Thermoform Plastic Sheets?
  • Most vacuum cleaner motors produce 4 to 5 in Hg (inches of Mercury) vacuum pressure, which means that most vacuums are equally suited for vacuum forming, regardless of their size. Larger vacuums with higher horse power will remove air from the former a fraction of a second faster than small vacuums, but their forming pressure (the force that pulls the plastic tight against the mold) will basically be the same.

What Materials Can You Use to Make Vacuum Forming Molds / Models?
  • Molds can be made out of any material that will not deform under vacuum pressure: wood, metal, plastic, plaster, and clay are all good choices. Choose a material that is easy to work with using the tools at your disposal.
