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, Carl Dell M70 SW...

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. Carl Dell M70 SW 2008 SP3.0

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, Carl Dell M70 SW 2007 SP1.0

I just found that what happens is that when I have my EJ Half display state active in the assembly then those balloons are fine and the Hot Half balloons disappear in the drawing. Same thing the other way. But if I have the Complete cavity display state active in the assembly then they all show...

My video card is certified but the driver is not the certified version for my card. It instead is the nvidia latest version. I used the Solidworks version for a while, but had several crashes (blue screen) which were caused by the video driver. Dell recommended that I use the later nvidia...

I am having trouble with balloons. I have two views on an assembly view drawing sheet. I use one for the hot half of my mold cavity and one for the ejector half. These views are of the same assembly, but are different display states to show the appropriate components.After I create my BOM, I...

Thanks for the reply Jeff. I don't get surfaces, just faces and the only option I can see is to delete the face not to hide it. There are no extra solid bodies, but I have run into that before. I apply my shrink to the part as well and use the combine (subtract) feature in a multibody part...

When I create a mold cavity and then extract out a corepin using the core function, I end up with separate faces at the area where the core is extracted from the steel and the area where the core is part of the mold cavity. This shows up on the drawing as a line that is misleading because it...
