<p>A method for manufacturing foam core materials comprising locating into a mold a solid activatable material, the activatable material being amenable to plastic deformation and pliable enough to take on the general contours and shape of the mold prior to activation of the activatable material. The method may further include simultaneously activating and shaping the material into a foam core defined by the mold wherein the activatabie material conforms to the shape of the mold due to the force of expansion of the activatable material during the activation.</p> |
