Mp#6- The technician Charlie Pack indicated that the press was stopping because the ejectors kept "bouncing" off the rear limit switch. He asked me to replace the switch and it did appear busted so I did. The problems still remained. I then attempted to adjust the EV2 potentiometer to "slow ejectors backs speed". Charlie also indicated that no control over ejector back speed was the problem. The EV2 pot changes did allow control over eject back speed, but the "bounce" problem remained still yet.

 Next, I discussed this with the supervisor Roger who thought the mold needed to have return springs in it. I mentioned that if I could find one, I could install a flow control with one way check valve in line with the hose and that would probably remedy this situation, but, I could not locate one anywhere. He also wanted to change the seals in the ejector cylinder.

The rod seal was not visibly leaking, but to be sure, I went ahead and tore it down and replaced the inside o-rings, rod seal, and both the piston seals. The problem of "ejector plate "bouncing" after retract still remains. The valve was my next choice, as I suspected drifting. It appears to still have the original valve on it. It was 12:00a.m. at this point so I went ahead and left. I will resume on it tomorrow when I come in.

Additionally, I would like to add that we could use some more seal kits for 360 ton Nissei presses as I had to re-use the external wiper rod seal because there was not one in the kit I found in MRO.

MP#8- The fan housing press was over-pressing the push-nut rivet assembly on the service parts they were running. I adjusted the positive stop to meet quality approval. I found out later that the process techs came back and adjusted it several more times. I think there may be some operator error being introduced to this operation. Check it out if anyone gets a chance. There could also be problems that have been overlooked with this process. Thanks.

Give me a call if you have any questions.
