Title: Moulding PVC
Post by: R.O.B. 2.0 on June 09, 2008, 01:58:35 PM

I've searched on google 'how to mould pvc' but I did'nt come up with any good answers. Is there any way to mould a PVC sheet besides vacuum forming for a small robot I am making?

Errr I wouldn't recommend applying a flame or anything, because I remember reading somewhere that the fumes given off by PVC are extremely toxic.  :o

Are all plastics like that, or are there a few that are different?

There are two types of plastic Thermoset and Thermoplastic. Thermoset burn when heated. Once they are formed they cannot be melted again. Thermoplastic can melt if the temperature is right. They can also burn if to much heat is applied. The reason PVC is toxic is the C in PVC. The C stands for chloride. That is a very bad gas to breath. I can't remember off the top of my head which classification PVC falls in but not all plastics are created equal.
