  • Molding apparatus and process
    Patent number: 10889026
    Abstract: A molding process (100) comprising the step of inserting an uncured blank (102) in a mold cavity (14) formed in a mold system, the uncured blank including fiber and uncured binder, transferring heat from the mold system to a cool pressurized gas (108) to establish a hot pressurized gas, injecting the hot pressurized gas into the mold cavity (110), and transferring heat (112) from the hot pressurized gas to the uncured blank to cause the uncured binder to cure and establish a cured product (114).
