Hi kenny, and welcome to the forum.
Personaly i think you would have to be very very carefull in trying this, as with most dart flights been plastic it would be vital to have the right settings on.
As there is nothing more anoying when you have to try clean your heat platen with any melted plastic ect.
On a personal way that i would do this, is that i would set the platen to no more than 9 seconds on a medium to heavy press.
If needed you could press again for another 9 seconds, but i would also use two pices of grease papper or teflon sheets and put the flights in between them.
This way you would save any issues or problems of the flights geting over heated and god for bid melting onto the platen.
With this type of help you are asking for on this subject, i would say its best to try some tests and then work from there what settings are best suited to you and your system you are useing.
Personaly m8 i would use m8 vinyl cutter and vinyl ect but then again it would put more weight onto the overall weight of the darts.
(yes as you have probs gathered i play darts lol)
Have a go at some tests m8, and i hope it all goes well for you
