1. A method for coating molded fiber products, comprising:
placing a molded fiber product in a product carrier, wherein the product carrier has a shape identical to the molded fiber product;
conveying, via a first conveyor belt, the product carrier to a first coating station;
coating a circumferential lip of the molded fiber product with a coating liquid;
filling a concave section of the molded fiber product with the coating liquid;
attaching the product carrier to a centrifugal axis;
rotating the product carrier around the centrifugal axis, wherein an excess portion of the coating liquid is removed from a surface of the molded fiber product; and
removing the product carrier from the centrifugal axis.
 
10. A method for coating molded fiber products, comprising:
placing a molded fiber product in a product carrier, wherein the product carrier has a shape identical to the molded fiber product;
weighing the product carrier with a first weighing device, wherein the first weighing device obtains a dry weight of the molded fiber product within the product carrier;
conveying, via a first conveyor belt, the product carrier to a first coating station;
coating a circumferential lip of the molded fiber product with a coating liquid;
filling a concave section of the molded fiber product with the coating liquid;
attaching the product carrier to a centrifugal axis;
rotating the product carrier around the centrifugal axis, wherein an excess portion of the coating liquid is removed from a surface of the molded fiber product;
removing the product carrier from the centrifugal axis; and
weighing the product carrier with a second weighing device, wherein the second weighing device obtains a coated weight of the molded fiber product within the product carrier.
 
16. A method for coating molded fiber products, comprising:
placing a molded fiber product in a product carrier, wherein the product carrier has a shape identical to the molded fiber product, wherein at least a portion of the product carrier is created using an additive manufacturing method;
weighing the product carrier with a first weighing device, wherein the first weighing device obtains a dry weight of the molded fiber product within the product carrier;
conveying, via a first conveyor belt, the product carrier to a first coating station;
coating a circumferential lip of the molded fiber product with a coating liquid, wherein a flat dish containing the coating liquid is raised to the product carrier, wherein the product carrier is lowered and the circumferential lip of the molded fiber product is submerged in the coating liquid;
filling a concave section of the molded fiber product with the coating liquid;
attaching the product carrier to a centrifugal axis;
rotating the product carrier around the centrifugal axis, wherein an excess portion of the coating liquid is removed from a surface of the molded fiber product;
removing the product carrier from the centrifugal axis;
weighing the product carrier with a second weighing device, wherein the second weighing device obtains a coated weight of the molded fiber product within the product carrier, and
removing the molded fiber product from the product carrier, wherein the product carrier comprises an air conduit port and a plurality of flow channels, wherein a vacuum system is coupled to the air conduit port, wherein the vacuum system is configured to apply positive pressure to the product carrier.
