Materials
A wide variety of materials are used in thermoforming, each having its unique capabilities, advantages, and tolerances. As you begin the process of deciding which material is correct for your next project, the information below should help you decide.
Tolerances
Over a period of time, accepted tolerances become industry standard. Should you need better-than-standard tolerances, just let us know. We’re happy to help.
As mold and part dimensions increase in size, so must tolerances.
| Activity | Tolerance | Guideline |
|---|---|---|
| Formed Measurements | +/- .020” | Additional .001 Per Inch Beyond 12” |
| Drilled Hole Diameters | +/- .005” | Holes Equal or Lesser than 1” |
| Drilled Hole Diameters | +/- .010” | Holes Greater Than 1” to 5” |
| Slots | +/- .010” | Slots Equal or Lesser Than 1” in Any Direction |
| Slots | +/- .020” | Slots Greater Than 1” |
| Robotic Trimming | +/- .020” | Includes Hole Diameters Greater than 5” |
| Robotic Trimming | +/- .020” | Trim Feature to Trim Feature Distance is Greater than 5” |
