    Re: Viscosity Study

    For me, a press of this vintage has wear in the pumps, bleed off of pressure through manifold blocks and valve stacks, not to mention leakage of hydraulic oil across the injection cylinder(s). Hence...

    Re: Color Shift

    Colorant probably has the wrong carrier resin in it. Most likely, they're using HDPE and its not liking the base resin. Either that or they used a pigment package in the color that isn't high heat...
  6. Re: “Splay” issue on PA66 GF30% with UV stabiliser.

    So your 'splay', should be the UV stabilizer being damaged or consumed in the barrel due to the high barrel temps, mold temps, and residence time. I've seen this many times when running UV or FR...
  7. Re: Creaking Sound and tool to platen wear, Engel Tie Bar Less.

    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...

    Re: preform tail breakout

    Maybe you have molded in stress causing the issue? A polarized light source and filter inspection could point out high molded in stress levels. I have also used chemicals like mold cleaner to...

    Re: Insert molding metal terminals

    I believe you will need to tweak the terminal design to ensure the melt flow and cavity pressure doesn't damage them. But, if not properly supported in the mold; they can move and may get twisted or...

    Re: M.F.R. Question

    I remember a resin supplier at one time would pull samples and watch the MFR of the resin. Typically you get low at the start- of a production run and high at the end. So they would go back and post...

    Re: Back Pressure

    Do you have a shut off nozzle? Without it, and without the proper software in some machines, you cannot continue to recover the screw while the mold opens and the parts are ejected; for the absolute...

    Re: Shop recommendations

    You also need to discuss the tolerances because that will dictate final costs. Also, can you use UHMWPE instead to save money on the parts? Even machining for those small quantities will be hard for...
  14. Re: Round pieces injection resulting squared problem

    Where is the gate? Gate size? Gate style? Mold and melt temps? What's the part length? Normally these are extruded due to these reasons.

  15. Re: Intermittent screeching noise during plasticising stage

    Does the press have a high torque screw plasticizing settings? If so I would turn it on. I would see if you can see the actual screw drive pressure/energy while plasticizing. I would bet that the...

    Re: Problem during TPE processing

    I would lower the barrel settings slightly as I believe the barrel capacity is low enough to cause cooking out of some of the additives in the resin. Also what size are the resin purchases? I ask...

    Re: Unsolved ınjection problems

    I suspect your barrel settings are too high for UV package in resin. Hence to odd locations. Need to reduce the barrel sertings, screw rpm and back pressure.
