  7. 7. Procedure Step 1 • Insert selected sheet resin material into the clamping frame. The S or screw-handle clamps allow adjustment of the frame according to the thickness of the material used.
  8. 8. Step 2 • Place model or cast on vacuum plate.
  9. 9. Step 3 • Slide clamping frame upward until it locks into position. Turn main switch on.
  10. 10. • Allow appropriate time (usually 2-4 minutes) for the material to heat sufficiently to achieve optimal sag for vacuum forming. Wait 2-4 minutes!
  11. 11. • Most other materials are heated until they sag 0.5-1 inch
  12. 12. • Milky, semi- transparent coping material should be formed when it becomes clear and barely begins to sag.
  13. 13. Step 4 • When the desired sag has been achieved, lower the clamping frame over the model. Activate the vacuum. A smooth, controlled lowering is recommended forthin materials.
  14. 14. Step 5 • Run vacuum motor for 10-20 seconds for thin plastics and 20-40 seconds for thick materials to ensure adaptation. Turn off main switch. Allow material to cool until it is comfortable enough to handle.
  15. 15. Step 6 • Trimming of the appliance.
