Mold testing

This is the core side of the tool, it creates the inside of the parts. This is also the side that the ejector pins are on.
The pins push the part out of the tool and they also leave the small round dots you see on the inside of a molded part.
The hoses are used to move water through the mold base and keep everything at a constant temperature.

This is the cavity side of the tool, it creates the outside or "show side" of the parts.
On opaque parts this is the half that gets polished.
*Unless your part is clear then the core and cavity will have the same finish.
Once we get the tool installed we create our test shots.
They are typically clear, it makes it easier to see whats happening during fit tests.
