Abstract

See full text

An injection mold and a method for ejecting, from the mold, a molded product having an array of integrally molded fastener elements extending from a base are provided. In some embodiments, the mold includes a series of ejector pins which progressively eject the product. In other embodiments, the mold includes moveable parts which pull fastener elements out of mold cavities without the use of ejector pins.
