Vacuum forming is used for molding thin sheets of thermoplastic material, typically seen most often in packaging applications.
Frequently Asked Questions
What is a thermoformer?
Sheets of thermoplastic are heated and pulled over a pattern using a vacuum.
What materials can I thermoform?
ABS (Acrylonitrile butadiene styrene) up to 1/4″, GTT* 260 – 280 °F
PETG (Polyethylene terephthalate glycol) up to 1/4″ – GTT 260 – 270 °F
HIPS (High Impact Polystyrene Sheet) up to 1/4″ – GTT 260 – 270 °F
Sheets should be cut to 20 x 18″
*GTT stands for Glass transition temperature, use an IR thermometer to measure the temperature before forming
How do I make a pattern?
Patterns can be made from a variety of materials. Commonly used materials for patterns include 3D printed parts, machined HDPE or Aluminum, and wood. Note, we do not work with wood in EPIC.
What is the maximum build volume?
19 x 17″ forming area
Max draw 11.5″
What are the limitations of Thermoforming?
No overhangs
Max depth of draw ~11.4″
No sharp corners
What tolerance should I use?
N/A. Not very accurate
