CSWPA MOLD MAKING EXAM

Maximum Mold Opening, as it applies to the actual mold, is:

The maximum distance the mold can be opened.

It is generally measured from the top of the mold to the bottom of the mold, with the mold in it's max open position.

For most molds the max mold opening is infinity, because the cavity & core halves of the mold are not connected to each other. But some molds can only be opened a certain distance, because they are interconnected and thus limited with regards to how far they can be opened.
