Abstract
Injection molding fastener element products employing a series of laterally moveable mold plates that define, in part, mold cavities for fastener elements. The laterally moveable mold plates move into open spaces provided by mold plates that retract or project in a direction normal to the base of the fastener product. This at least partially opens the fastener cavities to release the fastener elements.
