  1. Re: Which manufacture has the best after sales support in your experience?

    I have had pretty good luck with Arburg service and I like their machines. Sumitomo makes a good machine, but I have had some problems with their service however. Engel's service is a little spotty...

    Re: cashew gate in pc/abs?

    I have run some with PC/ABS. It was a touchy process and once it was running you didn't want to stop it.
  3. Re: Three resin lots required for part qualification

    I have never had to run three lots of resin, but I am guessing it is to prove the process is stable with changing lots of material. If it isn't something that is a super critical part I would just...

    Re: Injection Molding Process Sheets

    Last place we did something similar to what JayDub is saying. They were kept in an access database (controlled) and the part/machine specific spec sheets were printed, laminated, and then put in the...

    Re: Injection Molding Process Sheets

    I know there are some systems. Suhas has an database he sells through Fimmtech that does spec sheets and all the scientific molding worksheets. I have seem them set up in an access database as well....
  6. Re: Designing a low energy plastic "chopper"

    Robert,

    I am not dismissing you from the group, I just said I can not help you. I am not the whole group. What I am saying is I can not help you anymore as I don't know of a single molding machine...
  7. Re: Electrical fault: Cycle stops midway through

    She does look old, but looks in pretty good shape from the outside
  8. Re: Electrical fault: Cycle stops midway through

    Alex,

    Hoping that is the problem and you can get back to molding!

  9. Re: Designing a low energy plastic "chopper"

    Robert,

    You asked three questions. One of them was "1. Will 15mm squares be processed by most injection molding machines ?" I have tried to answer this question for you to the best of my ability...
  10. Re: Designing a low energy plastic "chopper"

    Robert,

    There might be some very large tonnage machines that can possibly "handle" it, but nothing that I know of that was designed to take something like that. May I pose this a different way....
  11. Re: Electrical fault: Cycle stops midway through

    I am not familiar with that machine, but you said you tested the microswitches and they work, but did you test to make sure they are being tripped when the nozzle is all the way forward? I would take...
  12. Re: Designing a low energy plastic "chopper"

    Robert, I understand you are passionate about this, but just trying to help. I appreciate that you are trying to help recycle material, but I am also trying to answer the question you asked. Most...
  13. Re: Designing a low energy plastic "chopper"

    Robert, what I was meaning is exactly what Platt1990 mentioned. It could get hung up in the feed throat of the machine and the issues with the screw as well as there is a finite amount of space...
  14. Re: Designing a low energy plastic "chopper"

    Robert, is this something you are planning to do to recycle material for you to use in a product of yours or for public use? If this is a device you are looking to sell for the general public to use...

    Re: Overmold Possibility

    Unless you did it as a two shot process or secondary process to cover it you will have to have some metal showing. Something needs to hold the metal plate in place in the mold if not it would float...

    Re: Yushin Robots in injetion process

    We use Yushin robots. Some of them you can program on the pendant however I would avoid doing that as it seems to crash them most of the time. Rick is right, contact Yushin. They will send you the...

    Re: Toshiba! Your favorite machine?

    I have horrible luck with Sumitomo as far as service and support. Their machines have some odd quirks as well. Not super fond of Engel's service either. I have had pretty good luck with Arburg. I...

    Re: Proper Short Shot - What do you think

    I am with Chris. Should be 95-98% by weight. Now in the finished product maybe the switchover needs to be adjusted for cosmetics, but the viscosity curve shouldn't be boxed in by cosmetics (other...

    Re: Modified gantry crane

    I have used the moving gantry cranes as well. Better than trying to do it with a forklift, but storage issues and moving them around can be a pain in a tight shop. Usually fairly cheap.

    Re: Nissei Press Training

    There are a lot of guys who train on site for processing. They may be able to teach stuff about the controllers, but my suggestion would be to get the manufacturer to come in and teach it or fly...
  23. Re: Pack and Hold: Van Dorn pathfinder control

    I think half the battle in molding is just figuring out each manufacturers quirks, terms, and where that flipping screen is you need!
  24. Re: Documentation Process for trials/validation of a new mold

    I know the feeling....been there, done that, and got the T-shirt. Only thing I can say is try and knock out the highest runners/problem childs first. If you can run some tests and make the part run...
