Problem with mold closing. Nissei Injection Molding.

[Techno Plast]

We have a Nissei 200 Ton machine. Two days ago the mold closing side
stopped working. We got the PLC checked and it is working fine.
Solenoids are working fine also. Suspecting problem with the oil seals
on the pressure side, we opened and checked the clamping cylinder.
Nothing there. Can anyone suggest anything else that we might be
missing out?

You got me. I think you covered all the things I usually check. Next step is to call in the Nissei people or somebody that is independent but used to work for Nissei. Bob
