Re: Heat set press
Whenever I have used PVA for laminating it has been dry mainly because it
prevents curling due to the fact the moisture and therefore shrinkage
and expansion is long gone.
Using wet PVA may in some circumstances cause blackening or your
laminates still to curl after pressing.
As far as temperature ranges are concerned (not knowing what
materials you use) I would experiment with scraps and start with a
fairly low temp. and try increasing gradually. This can also be
inversley proportional to the time the objects are in the press so
try adjusting times as well! (for cartridge we tend to operate at
around 100 C for 1 minute)
Hope this helps.
PS have we any clever uses no-one knows about for these machines?
