Abstract: A method for coating products is provided. The method includes the steps of applying a coating liquid to a product and removing excess coating liquid from the product. It is desirable to provide a method for efficiently and reliably coating delicate or easily deformable products, such as products molded from a pulp fiber slurry. The method includes fixing the product to a receiving portion of a product carrier that is configured in the same shape as the product, such that an exterior surface of the product abuts the interior concave surface of the receiving portion of the device. A coating liquid is applied to the product in the product carrier. The product carrier is affixed to a centrifuging device and the coating liquid is dispersed over the surface of the product using centripetal force.

Abstract: The present invention is directed to a 3D printed mold for creating three dimensional pulp products from a fibrous pulp slurry. Transverse filaments are integrated into an infill structure with an open-cell pattern. The transverse filaments form channels through the interior matrix of the mold. The open cell infill pattern and channels allow for the movement of vacuumed materials through the interior matrix of the 3D printed mold when vacuum pressure is applied. The product surface of the mold comprises an array of beads formed from the over-extrusion of melted material at the ends of the transverse filaments. The beaded array narrows the opening of the channels created by the transverse filaments, preventing the fibers from entering the matrix of the mold and clogging the flow of materials. This causes the fibers to aggregate on the product surface of the mold, forming the three dimensional pulp product.

Abstract: The present invention is directed to methods and systems for manufacturing molded fiber products using a pulp slurry and apparatus submerged in pulp slurry. The system utilizes a vacuum and mesh shaping of the product to pull fiber from the pulp slurry to the mesh shape while sucking the water through the mesh shape. The molded fiber product is then pressed to bolster the strength and structure of the product. The product is then coated using centripetal force to uniformly spread the coating across the selected area of the product. After coating, the product is pressed again to ensure the waterproof and airproof structure of the product. The materials used in manufacturing the molded fiber product are biodegradable, and the apparatus to form the molded fiber product is shaped according to the desired shape and size of the product.

Abstract: The present invention includes a system of multipart devices for the formation, pressing, and coating of molded pulp fiber articles. The system includes a mold device, a pressing device, and/or a coating device. Each device comprises a screen fastened or otherwise connected to the housing unit. The housing unit is a solid, non-porous housing element, and multiple housing units are configured to be reversibly connected to form a single device. When joined together, the screens of each housing unit form a continuous cavity for the molding, pressing, and coating of the product. The housing unit of a mold device comprises one or more vacuum systems which direct vacuum pressure to the product surface of the mold screen to form a pulp fiber product from a pulp fiber slurry. The pulp product is operable to be dried in the mold device, resulting in the formation of a stable, thin-walled pulp product.
