Rear foamed composite component manufacture, involves coating the rear side of the decorative facing layer to prevent foam penetration of stitched seams and appearance on the visible face

摘要

A stitched outer skin (12) is placed in a tool and foamed plastic molded onto the rear side. Foam penetration through the seams (14) or other defects is prevented by forming a barrier layer (30) in the mold either before or after laying the skin. The barrier layer is applied to the non-visible side (26) of the skin by spraying (28).
