Claims12
A molding process for molding a cured product, the molding process comprising
- providing an uncured blank including fibers and uncured binder,
- inserting the uncured blank in a mold cavity formed in a mold,
- closing the mold to trap the uncured blank in the mold cavity to cause the uncured blank to assume a molded shape,
- transferring a shaping heat to the uncured blank to cause a portion of the binder to be cured so that the molded shape is retained after the removal from the mold and a shaped product is established,
- opening the mold to release the shaped product,
- inserting the shaped product in a heater, and
- transferring a curing heat to the shaped product to cause a remainder of the uncured binder to cure so that a cured product is established,
- wherein curing of the binder consists essentially of a Maillard reaction.
