Hello, all.
Is Delrin (Acetal) able to survive vulcanization? Thanks in advance.

No, nor should this be attemted. Delrin has a low melt point of 275-280F over 395F delirin gives off formelahyde gas, which is highly toxic & dangeruse.

Trials so far a failure!

NO,
mechainical fasteners only. IE: botl or screw from behind, or a groove & clamp. Delirin is a popular bushing surface, used in electronc such as VCRs, DVD players and so fourth. Where a steel plate with have molded features for shaft support.

I thought that Loktite had a product that could glue delrin.

I do not agree with Mark,
There are low temperature vulcanized rubbers
that are ok with Derlin, they just need 60-70°C for vulcanization. This
is a lot under the Derlin melting point.
Another good material for
tooling can be ureol.
Hope it helps

I have had some success in reattaching Delrin only where there is
absolutely so stress on the joint (appearance only item, for
instance).
What I had to do was to drill a hole(s) in both pieces and install a
piece of wire, kind of like they install a short length of Rebar when
replacing a section of concrete roadway. In order to keep proper
alignment, it is necessary to clamp the pieces together and drill in
from the outer surface of one of the pieces. Drill from a spot that
is hidden if possible. If the piece is large enough, use more than
wire connector. Use as many as possible. Rough the mating surfaces
slightly and assembly with epoxy. If a long enough piece of wire is
used, you can then file down the end that would stick out to plug the
hole.
I would think that this would work for a mold master although I have
never tried it.
