Shrinkage for plastic part

Shrinkage for plastic part

Shrinkage for plastic part

(OP)
Hello,

  I have a already finished plastic part (PPA). But shrinkage is not considered in the design. How to compensate now. Or normally, how it is done in catia. Should we consider in product design stage itself. I am new to CAD design. request you to explain in detail.Material has different shrinkage in flow direaction and other direction.

Any help would be nice.

Thanks

RE: Shrinkage for plastic part

I only have a couple of years on CATIA 5 but I have done some cast parts and hot sized parts both have shrink predictability requirements.
CATIA has a scaling factor that is based on a centroid point this is a little of a black art if the part is complicated like the engine head I just completed.

So check it out @ insert+transformation features+scaling
Make sure you are in part body and that you have a established point..

Cheers

I don't know anything but the people that do.
