Abstract:
1. A method for manufacturing filtration units, comprising a structure having a box-like enclosure and at least one filtration element where said at least one filtration element is locked in a thermoplastic retention element in a seat in said box-like enclosure said method comprises: (a) injecting with injection means, said retention element which is a thermoplastic polymeric material in a fluid state, into a space in said box-like enclosure, which is adapted to engage said filtration element where said space is defined by a seat having a bottom and two side walls and in collaboration with a closure means of an apparatus having hermetic closure means that form a closed volume with said seat in said box-like structure for containing said thermoplastic retention element, said hermetic closure means having a face with at least one non-stick region which contacts a surface of said retention element wherein said apparatus comprises said injection means wherein said injection means has a port for dispensing said thermoplastic polymeric material in a fluid state into said seat in said box-like element to form said thermoplastic retention element; (b) embedding at least one end of said filtration element in at least one portion of said thermoplastic retention element while said thermoplastic retention element is in the fluid state so that said filtration element is locked to said seat of said box like enclosure; and (c) providing a region within said seat where said region is under a vacuum for receiving said retention element in said seat where said retention element is injected under pressure; and (d) solidifying said thermoplastic retention element to form a solidified retention element in order to lock said at least one filtration element in said seat of said box like enclosure.
