Re: Thermoplastics in FIRST

my team has a sort of jury rigged method for molding plastics as well as mold abilities for smaller parts. we made several attachments for a soldering iron to melt plastics together, basicaly the two strips op plastic are put on either side of a high heat brass plate on a soldering iron, held there until tacky, then the soldering iron is pulled out and a heat gun is used to keep the plastic as sticky as possible while it is pressed together very tightly, we also use a heat gun to heat lexan up to near melting point and then put it on a sheet metal break, this makes bending thicker plastic with a break easier, as well as makes the whole thing cleaner.
