General Usage Instructions

Sheet temperature is the most critical element of the vacuum-forming process.

Know Your Temperatures!

  • Uniform Sheet Temp
  • Sheet Core Temp vs. Surface Temp
  • Temperature difference between sheet and mold
  • Temperature Zone Control, profile for the sheet.

Uniform Sheet Temperature

Oven zones may need to be adjusted to achieve uniform sheet temperature. May need to shade the temps across the sheet for certain molds.

The Core Temperature

The sheet core temperature will correspond to the material thickness. On thicker materials, you may need to heat slowly to achieve the correct core temperature.

Temperature Variance Across the Sheet

You should check all four corners and the center of your sheet. The temperature of each area should not vary more than 5 degrees. Don’t just crank up the temps, you should adjust the zone temps.
