Standard ports make every hookup a five-minute job.
Why standardise ports
Mixed thread types and port sizes across a mold fleet multiply connector stock, hose confusion and mis-connection risk. A house standard for port thread, size and location makes molds interchangeable between presses.
Consistent port placement also protects them from fixture and clamp collisions.
Details that prevent leaks
Machine O-ring seats to the specified finish and inspect them at maintenance — a scratched seat leaks slowly and wets surfaces that then corrode.
Keep channels clean and tagged; document the circuit layout so future maintenance does not guess.
FAQ
Which thread standard should we adopt?
Adopt the one your plant and suppliers already support; the benefit is uniformity, not the specific standard.
Why do ports leak after many cycles?
Usually worn O-rings or damaged seats — both are consumable details to inspect at PM.
Should circuits be labeled on the mold?
Yes — inlet/outlet labels and a circuit diagram prevent mis-connection and speed troubleshooting.
