Title
(EN) USING FILM TO PROVIDE A PREFORM FOR MICRO INJECTION MOLDING PROCESS
(FR) UTILISATION D’UN FILM DESTINÉ À PRÉPARER UNE PRÉFORME POUR UN PROCÉDÉ DE MOULAGE PAR MICRO-INJECTION
Abstract
(EN)
A mold assembly 100 for forming a microneedle array, wherein the mold assembly facilitates expulsion of trapped gasses from the molding system. The mold assembly may comprise a first mold portion 102 comprising a plurality of recesses 104 formed therein, a second mold portion 106 disposed adjacent the first mold portion, wherein a surface of the second mold portion and the plurality of recesses of the first mold portion define a mold cavity, a mold film insert 112 disposed within the mold cavity between the first mold portion and the second mold portion of the mold assembly, the mold film insert comprising a plurality of perforated layers 114, each of the perforated layers comprising a plurality of perforations.
