Abstract
A modular plastic floor tile has a body of a first polymer compound and at least one upper feature overmolded onto an upper surface of the body from a second polymer compound which is injected from a gate adjacent the lower surface of the body. At least one through-hole communicates the gate to the upper feature. At least one vent hole, spaced from the through-hole, communicates the upper feature to the lower surface of the body. The vent hole allows any gas in the polymer flow path to be displaced from the upper feature, thereby preventing or minimizing defects that can affect adhesion and appearance.
