What type of plastic should I use for heat forming?? Answered
I need help selecting a type of heat-forming plastic. Can any plastic experts offer advice?
I'm nearing the end of the design phase of a project, and I need some help selecting the right material with which to make it. I'll essentially be building a solid, 3-dimensional form by setting a plastic sheet over the form and hitting the plastic with a heat gun, and then trimming.
Are there any plastics that would "droop" onto the form when heated, but stiffen up again properly when they re-cooled? A pliable, but still fairly rigid plastic that resembles the stuff those cheap black plastic oil receivers are made out of would be ideal.
If this type of plastic exists, where would I get it? Also, what thickness would be best? I would like it to be as thin as possible, but still function as described above. I have looked into vacuum forming, and while AMAZING, it is too expensive/difficult for my purposes.
