Laminate plates are used to help make laminates with your existing mold. They simply clamp to one side of your mold (2 clamps) allowing you to inject half a bait. You then remove the plate and runner and inject the other side of your bait.
I inadvertently made 2 different molds from an alignment pin perspective. The cavities themselves are identical, but the alignment pin is reversed on some of them. This is irrelevant to the baits, until you put a laminate plate on the mold. Please look at your mold, spru up, and see if your alignment pin is on the left or right side of the mold. If you can select which side the pin is on (left or right) from the drop down above, this will ensure you get the correct laminate plate. Sorry for the inconvenience.
