Cincinnati Milacron 3-542-1130A is a vintage printed circuit board that functions as a control module in Cincinnati Milacron injection-molding machines. Marketed across distributors as a memory expansion board or control card, this PCB is part of the machine’s control electronics and is typically sold as a used replacement pulled from decommissioned equipment. Listings note provenance from Milacron machines in the VSX family, including an example removed from a VSX 55-1.08, and some suppliers record a Rev B revision of the part. As a used Milacron control module, it is commonly sought for replacement in aging equipment and for restoring vintage Milacron controllers.
