Howdy guys,

hope this question is not too far out of the scope of this newsgroup, but it
appears to be the best newsgroup for working with delrin discussion.

I have a pile of used acetal/delrin scrap that I've collected. All the same
item, from the same manufacturer, so no blends of brands/types.

I've googled acetal/delrin to death and cannot find any mention of
recycling it into new items. Is it safe/easy to melt and pour into a simple
cast? I want to make it into 4" x 4" x 2" blocks to then machine

I'm aware that melting starts at 180 deg c and Formaldehyde is released at
230deg c.

Any suggestions on making a simple mold? Will a machined out block of
aluminium with a bolted on bottom (think of a tube with a cap at one end)
that can be disassembled be good enough for mold release?

Any help is greatly appreciated,

Regards,
Mark
