圧脱水及び加熱乾燥の２工程を要していた。Conventionally, as a method for manufacturing a valve molded product having a certain thickness, a slurry-like suspension of pulp in water (hereinafter referred to as pulp liquid) has the shape of an object to be molded. A male or female adsorption mold with many fine holes on the surface is immersed, and a vacuum is applied from inside the mold to adhere pulp to the surface of the mold until the adhesion layer reaches a predetermined thickness. When this is done, the mold is removed from the pulp liquid, and then a pressing mold and a heating mold having male and female shapes corresponding to the molds are placed therein, and the desired molded product is obtained by dehydration and drying. In other words, when using the above method, two steps of press dehydration and heat drying were required.
