Abstract
A monolithic drain body including a base wall defining an outlet and a periphery, a side wall extending from the periphery of the base wall to produce an open end opposite the base wall, and a ledge formed into the side wall and extending inwardly therefrom to at least partially enclose a first volume between the ledge, the side wall, and the base wall.
Claims20
A method of manufacturing a drain having a monolithic body, the method comprising:
- forming a first monolithic piece of sheet material over a first exterior surface of a die to produce the monolithic body, wherein the monolithic body has an internal volume having a first cross-sectional shape accessed via an aperture having a second cross-sectional shape that is smaller than the first cross-sectional shape;
- and
- removing the die from the internal volume via the aperture.
A die having an external surface configured to at least partially form an internal volume, the die comprising:
- a head unit defining a die axis, wherein the head unit includes a first end and a second end opposite the first end;
- a first die segment removably coupled to the head unit, wherein the first die at least partially forms the external surface;
- and
- wherein when the first die segment is coupled to the head unit the resulting assembly produces an assembled cross-sectional shape taken normal to the die axis and passing through the first die segment, and wherein the first die segment can be completely detached from the head unit without extending outside the assembled cross-sectional shape during the detachment process.
