There are also vertical machines, of which I have worked on. The moving

Vertical machines are a lot easier to work with when you have to do insert
stuff as the bottom half of the mold doesn't move and can have parts put on
it to be molded into the plastic with no fear of the part falling out and
being crushed into the mold as the mold closes.

From what I've seen, they also tend to have much lower injection and
clamp pressure (and thus more suited for injecting the plastics used
for molding cables onto connectors and such like).

Yeah. And what is going to keep the tool lined up? In order to get
the part out after ejection, the tool will have to open beyond the
proposed "skirts" pl;us enough for drop-out , and as soon as the
edges clear there will be no alignment. Besides, there will be either
extreme wear or extreme lube all over the place. Guide pins have
multiple purposes.

Take care.
