Method of producing pulp moldings

A method of producing a pulp molded article, the method comprising:

• joining a first split and a second split, thereby forming a cavity;
• feeding a first diluting fluid into the cavity;
• feeding a first pulp slurry into the cavity;
• and
• sucking the first pulp slurry through suction passageways formed in at least one of the first split and the second split to form a first pulp layer,
• wherein a concentration of the first pulp slurry is greater than a concentration of the first diluting fluid.

• a volume of the first diluting fluid is in the range of:
• (¼)(ρs)·Vc<Vw<8Vc,
• where Vw is a volume of the first diluting fluid, Vc is a volume of the cavity, and ρs is a weight percentage (concentration) of the first pulp slurry.

• feeding a first diluting fluid into the cavity;
• feeding a first pulp slurry into the cavity;
• feeding a second diluting fluid into the cavity after feeding the first pulp slurry into the cavity;
• and
• sucking the first pulp slurry through suction passageways formed in at least one of the first split and the second split to form a first pulp layer,
• wherein a concentration of the first pulp slurry is greater than a concentration of the first diluting fluid.
