This looks like a jetmaster controller (Chensong) ?

Not too much experience with Nylon but it is a hygroscopic material - wont this perhaps cause some of your issues? The longer the part is out the mould the more moisture it absorbs. When we pack our...

Could have some blockage in the nozzle, small piece of steel, just small enough to allow material through but cause plenty of shear heating. I had an issue once where the screw tip broke off and was...

I have experienced this before - The issue for me was Degradation of material. I lowered TEMPS and also in my case lowered the dose on the Masterbatch.

There is no short cut to leveling a machine. The torque wrench will help with the leverage when adjusting the nuts and the also the ratchet function will help but once the nuts go under strain you...

I think they work on 10V. you could try and shift the potentiometer so that it uses a different position, in other words it shifts the wear marks. It means you will have to recalibrate your...
