Hi folks,
Thanks for all the tips and ideas.
potteryshard: That's something I was reading up too. Is there a way to test that?
TurbineGen: No, the temperature is relatively constant and the motor is not contantly in use (> 10% duty rate).
I called the distributor last week - not only do...
Thanks a lot for your reponses.
I really thought that the reason why the original design used steppers what that overloading them will not cause damage.
What can I do to verify the intergrity of the magnets?
Hi folks,
I have a strange noobs problem that I can not wrap my head around. I have a plastic tubing stretcher that uses a stepper motor (Minebea 23KM-K709-07) to precisely do the stretching without going through any gearboxes etc.
It was working just fine for a long time, until one day, the...
Hi folks,
I'm making some thin-walled containers via stretch blow moulding out of clear PEBA and Nylon 12. On some runs, some of the parts have silvery-white patches on them, especially around bends and edges (ex: where the side wall meets the bottom).
Any ideas on what might be the cause...
I'm using PA12. The weird thing is that I've done it before for a part at 25mm diameter. Our customer now wants a different model at 29mm, which so far has been eluding us.
Hi folks!
I'm running into this problem that I'm having issues wrapping my head around, and I hope that someone will have some ideas to inspire me.
I was wondering if anyone has faced a problem where the preform used in SBM blows up 1/2 way during the stretching/inflation process. Tried...
Hello,
I'm currently looking into a material that can be blown into strong, (almost optically) clear films.
We're currently doing some stretch blow moulding for a client on transparent bag-like food containers with very thin walls (.0025" in thickness) and have been experimenting with some...
