Abstract

A mold is provided for forming a grommet element. The mold includes a stationary portion and an axially movable portion. The grommet element is formed by the steps of installing respective connecting terminals on conduits; forming a conduit assembly from a plurality of individual conduits, and banding together two proximal points of the conduit assembly; introducing the conduit assembly into the lower part of the mold; closing the mold; moving the two proximal points closer together to produce flexural buckling of the conduits in the conduit assembly; introducing an adhesive mass into the mold, under pressure, at an elevated temperature, during a predetermined period of time; injecting the hot adhesive between the conduits of the conduit assembly; cooling the mold to solidify the adhesive; and molding PVC or another thermoplastic elastomer over the adhesive-sealed conduit assembly, to form a grommet element, and joining the thus sealed conduit assembly to a flange or dividing wall.
