PROCHECK is ideal for blister/drape forming of short term Diagnostic check sockets for walking trials due to its good clarity, mechanical strength, excellent vacuum formability and reproduction of detail. It is physiologically safe with crystal clear optical transparency and a shrinkage factor of less than 1%.
Recommended Oven Temperature for blister / vacuum forming is 165 Deg C with an oven cooking time of approx. 2 minutes per mm of sheet thickness, (oven dependant).
ProCheck, if heated above the recommended temperature, will be seriously weakened due to the molecular breakdown that will occur.
Clamp plastic in a frame and allow blister to droop approx. 2/3 to ¾ full length of the model that you are vacuuming over. If you require more droop than this, use a larger frame or a thicker material.
When heating ProCheck in the oven, it is recommended that the plastic be inverted after an initial droop of approx. 15mm has formed, repeat this procedure three to four times. This will assist greatly in producing a good quality socket with very uniform wall thickness and minimal shrinkage of less than 1%.
It is strongly recommended that you drape in an area where the windows are closed and there are no cold draughts that may prevent the material from cooling down slowly and evenly. Avoid uneven cooling which will shock the plastic on one side resulting in differential shrinkage creating residual stresses in the plastic.
Drape by inverting the bubble, (bubble up) on small to medium length casts where the plastic doesn’t have to drop that far.
Drape through the bubble, (bubble down) on long casts because the longer the plastic droops in the oven, the more difficult it becomes to invert over the cast and will sometimes fall back on itself, sticking to itself and rendering the plastic unusable.
The socket geometry can be Thermo-Remodeled by the application of heat, taking care that the plastic is heated slowly, evenly and not overheated.
