Creaking Sound and tool to platen wear, Engel Tie Bar Less.

[Suhas]

Hi,
That is an interesting observation. I have not seen that but I have always heard the large machines creak and make noise during injection.
Sorry, not of much help.

Not sure about your side to side measurements, but with horizontal witness lines across the middle of the tool I would suspect that the machine is out of level

Hi ijchan23, thanks for your reply, the machine was set up by our local Engel agent on a quality 6 inch concrete floor. If you look at my CAD drawing you will note that from the dial gauge readings it shows that the fixed platen is flexing vertically through the centerline of the fixed platen and this is why it appears we are seeing the distance between the tool to edge of the platen reduce on both the front and back causing the metal fretting and creaking sound. This isn’t happening on the moving platen and hence no metal fretting.

One question: Does this press have the 'scroll block' deflection system or the newer one looking two or more blocks?
I have never seen this on the scroll block style but with the newer ones I have and its an issue with the pre-load applied to the moving platten. I also have seen this when the stationary platten is loose, damaged, or someone drilled a platten or frame and it has propagated a crack.
