Thermoforming result does not satisfy.
There can be different reasons for that, e.g.
-
model has a sharpe
edge (a hole in the foil is resulting)
-
heating unit is too weak (too
old)
-
thermoforming unit is damaged.
With not program-driven units:
overheated foil or heated up too shortly.
Higher models should be embedded into the granules. Compress the
granules.
With not program-driven units:
Foil has to run through
the following different phases: It raises, it lowers, it becomes
wavy, it becomes transparent, it smoothes itself out - time to thermoform.
