[Object] To provide a fiberboard manufacturing method that is suitable for efficiently manufacturing a fiberboard in which warpage is suppressed, and to provide a fiberboard that is obtained by such a fiberboard manufacturing method.

[Solution] The fiberboard manufacturing method of the present invention includes the following pulp crushing step S1, mat forming step S2, and hot-pressing step S3. In the pulp crushing step S1, pulp dispersed in water is beaten in a gap between opposed blades to thereby produce a plant-based fiber material that has a particle size D50 of 50 to 110 μm and a freeness value of 150 to 300 ml and that contains an adhesive component. In the mat forming step S2, a mat is formed from the plant-based fiber material. In the hot-pressing step S3, by hot-pressing the mat, a fiberboard is formed from the mat through a process of plasticizing the adhesive component in the mat.

A single-walled disposable cooler is provided and generally includes a body and a lid. The body is generally made from a pulp-based material or fiber-based material and includes a base and a plurality of support walls coupled to the base. At least one of the plurality of support walls includes a substantially planar surface. The plurality of support walls and the base define an interior cavity of the body, while the plurality of support walls extend upwardly from the base to form an opening at an upper terminus of the body in fluid communication with the interior cavity. The lid is also made from the pulp-based material or fiber-based material and corresponds with the body. The lid is shaped to cover the opening of the body.

According to examples, an apparatus may include a processor that may access information about a screen device having pores, in which the screen device is to be employed to filter liquid from a slurry composed of the liquid and material elements to form a part from the material elements. The processor may also access information about a main body, in which the main body is to support the screen device during formation of the part and has a plurality of openings that are larger than the pores in the screen device. The processor may identify, based on relative locations of the pores and the openings, pores that are to be removed from the screen device to increase uniformity of liquid flow through the pores across the screen device and may modify the accessed information about the screen device to remove the identified pores from the screen device.
