Beginners' Guide to Melting HDPE - How to Make a Recycled Plastic Pen

I love this process...melting (technically it's softening not melting) HDPE on a panini press between parchment paper (they call it greaseproof, but that's parchment in the US)  and pressing it into a mold looks like something I could maybe actually do.

So I started collecting lids since the beginning of the year. I don't have nearly enough, though, so I'm going to have to expand my collecting efforts.

Clearly their processing has gotten much, much fancier as the jewelry making video shows. They're on to injection molding, oven melting, and machined aluminum molds.

I'm thinking I'm a ways away from that, but I want to try this next year with my students.
