A method of forming a component (28; 50) from a part in a green state through a powder injection molding process, the method comprising: forming the green part having an initial planar shape including: injection-molding at least one first portion of the green part in the initial shape of the flat panel with a first feedstock; and injection-molding at least one second portion of the green part with a second feedstock to obtain the component, wherein: the at least one first portion has a first volume of powder material V P1 and a first volume of binder V B1, the at least one first portion having a first solid loading defined as V P1 /(V P1 + V B1); and the at least one second portion has a second volume of powder material V P2 and a second volume of binder V B2, the at least one second portion having a second solid loading defined as V P2 /(V P2 + V B2), the first solid loading greater than the second solid loading, wherein a difference between the values of the first and second solid loadings is at least 0.01; and curving the green part having the initial planar shape by debinding and sintering the part to obtain the component (28; 50), wherein the curving includes obtaining a final desired shape of a curved panel after the sintering by having the first and second solid loadings producing a different local volume reduction in the at least one first portion with respect to the at least one second portion (46, 60d, 62), wherein sintering the green part is performed with a surface of the green part placed against a shaping surface of a setter, the surface of the green part not conforming to the shaping surface, the surface of the green part defined by the at least one second portion, and the first solid loading being greater than the second solid loading causing the at least one first portion to undergo the smaller local volume reduction than the at least one second portion during sintering to deform the part to conform the surface to the shaping surface of the setter. forming the green part having an initial planar shape including: injection-molding at least one first portion of the green part in the initial shape of the flat panel with a first feedstock;
