You think that is bad, I have been practically exploding my brain trying to
work out how the heck they injection mold the chains.
Each link is a single piece, so all the links must be molded in place. I
can't imagine that they mold the entire thing in one go (imagine how complex
and precise the mold would need to be) and the best method I can come up
with is that each alternate link is molded in the first pass, and then the
rest of the links are molded in a second pass.
I don't know - I've been trying to visualise the mold, be cant! (and I have
done injection molding during my university days!) At the VERY least it
would need to be a four part mold.
