Abstract
A method and means for attaching flexible, low density or compressible structure such as foam to injection molded parts, wherein a mold has a recess shaped for a corresponding flexible, low density or compressible structure. A valve plate made of injected material is placed against the foam structure to compress and protect the foam structure from molten injected material. The valve plate has through apertures for limited access of the injected material to predetermined surface portions of the foam. The molten injected material forms an adhesive between the foam structure and valve plate to adhere the foam structure to the valve plate, and the resultant final component assembly.
