A uniform cooling of the part is important in the injection molding process in order to reduce shrinkage and warpage.
Especially in long and narrow areas, the cooling layout is often difficult.
This is because the space is insufficient to drill holes next to each other.
Therefore, when there is only enough space for one hole, it is recommended to use a baffle.
It is inserted into the hole and redirects the coolant from one side into the hole and out on the other side.
Injection Molding: The baffle consists of a drilled hole with an inserted divider plate.
