Thanks again Paul and Pud.
I do not have a mold base yet and I think I will go with bolting the cavities on the plates and eliminating the pockets. As you say Paul, there is no reason for pockets if the cavities can have some kind of alignment feature. I love gaining a different perspective...
Thanks for the responses Mike and Paul,
My experience is with steel cavities in standard steel mold bases. My customer is looking for cheaper cavities and this is a low volume project with 3 pretty big parts (9" diameter) thus my thought was to make aluminum cavities that would be...
We are going to make some aluminum cavity inserts for 3 different molded parts that will be interchangeable in a single cavity mold base. I am most comfortable with a steel mold base but am concerned about thermal expansion. The inserts will be about 10" square. The material we will be running...
Thanks guys for the responses. You confirm my thoughts that these voids are probably unavoidable. They are very small so what we are getting is actually quite good. My customer machines a lot of small quantities of parts so a mold is typically not justifiable if they can get material and machine...
We have built a cavity to mold a 6" X 6" X 1/2 thick plate of Fortron with 40% glass (similar to ryton R4. We are having trouble with some slight porosity in the center of the parts. We then made the cavity smaller in steps to the point that the cavity is now 3" X 3". The runners are 5/16...
I must be misunderstanding the question but if you just want to add a revision to an existing table all you have to do is RMB on the table and select Revisions - Add Revision. This will add a line to the table with the next rev level and you maintain the previous revisions without having to...
dpackard,
We run this material a lot with subgates. The only mold we have trouble with is one where the gate comes in on a fairly shallow compound angle. I can definitely avoid this on this part since there is plenty of depth to gate into.
cpretty,
Good to hear. I have gotten advice that this...
patprimmer,
I don't know what you mean by straight shot and hot shots. I like the idea of a tab or a ring gate as long as it can be broken off close before machining. We currently mold this part with a diaghram gate which makes for an extra machining step to cut it out.
Thanks for the advice...
cpretty,
That is what I was envisioning with the three plate mold. We should have room for subgates there. As I said, I am a little concerned about dropping sizes in the flow of the plastic. I would be very interested to hear if you have any problems filling the parts.
Thanks,

We would like the part to degate. If there is some vestige that would be ok because the customer has to cut a groove on the ID anyway, but we don't want a separate operation for just the gate.

I am designing a 4 cavity mold. The parts are rings that are 1.5" OD, 1.25 ID by .375 thick molded of 325 valox (PBT). My customer would like to see the gates on the ID of this part. He machines these and from his experience if we were to subgate on the OD there can be a visual mark where the...
There is some of this functionality in SW. If you have some items hidden in an assembly you can RMB on the assembly in the feature manager tree and select Show with Dependents. This will show all items in that assembly. This works on the top level assembly as well as subassemblies.
The context...
I changed my views to use different configurations instead of different display states and everything seems to work fine. This is probably the best solution to the problem of disappearing balloons.
I like display states because they are so easy to create using the isolate command, but the...
Another factor in this is that I am using a custom property (det #) in my BOM and in the balloons. I just tried a simple assembly using the item number to populate the bom and the balloons and the display states did not affect them. When I changed to the custom property in the balloons then they...
Alright, I will upgrade to 3.0 and see if that helps, but at least I now know how to make them show up.
Thanks for your help CBL,
