Abstract
A molded fiber part former includes a first forming mold defining a first mold area and at least one fluid inlet. The molded fiber part former also includes a wall substantially surrounding the first mold area. The molded fiber part former includes a fluid channel disposed adjacent to and surrounding the wall, wherein the channel is fluidically connected to the at least one fluid inlet and defines a fluid channel outlet.
Claims9
A method of producing a molded fiber part, the method comprising:
- disposing a first forming mold into a slurry tank comprising a plurality of fibers and a liquid, wherein the first forming mold comprises a first mold area, at least one fluid inlet, and a plurality of vacuum channels;
- actuating a vacuum communicatively coupled to the plurality of vacuum channels to draw at least some of the plurality of fibers onto the forming mold to form a partially-formed molded fiber part;
- removing the first forming mold from the slurry tank;
- applying a compressive pressure to the partially-formed molded fiber part with a second forming mold;
- separating a waste trim from the partially-formed molded fiber part substantially simultaneously with applying the compressive pressure;
- and
- subsequent to separating the waste trim, transferring the partially-formed molded fiber part to a downstream station,
- wherein separating the waste trim comprises receiving a fluid from the at least one fluid inlet and ejecting the fluid from a fluid outlet at least partially defined by the first forming mold.
