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.
