Hi All, I have a question for CSWPA mold making ? Shrink rate : scale up or scale down ? I do not know when to decrease and when to increase.

Think about it from a temperature perspective. When the part is in a mold, it is hot. A hot part is bigger than a cold part. If a customer provides a fully designed part to a mold maker, the mold maker will have to scale it up larger by some factor in order to design their mold. This way, when the finished part comes out of the mold and finally cools down, it will shrink to the designed dimensions as provided by the customer.
