Process for manufacturing a lightweight retractable shower door enclosure and a lightweight shower door enclosure manufactured thereby

Abstract

A method of manufacturing a lightweight, plastic shower door enclosure for enclosing a shower in a limited space environment includes providing a supply of a plastic polymer material for each part of the shower door enclosure to be manufactured, feeding the plastic polymer material to a rotating screw arranged within and along a central axis of a barrel feeder, controlling a rotation of the rotating screw to mix the plastic polymer material while compelling the mixed, plastic raw material forward through a heated portion of the barrel, ejecting the mixed, heated, plastic polymer material through an adapter and/or die as an extrudate supply for forming the each part and cutting the extrudate to the dimensions of the each part of the shower door enclosure.
