Abstract
A coextruded polymer molding product includes a notched structural carrier and a polymer seal material over the structural carrier. The structural carrier has notches along its length A first plurality of specific regions of the structural carrier have notches. A second plurality of specific regions of the structural carrier are relieved from having notches. The notched regions and relieved regions are arranged with respect to each other such that consecutive notched regions are spaced apart at non-uniform intervals to provide desired bending characteristics for conforming to a specific molding application.
Claims22
A method of making a coextruded polymer molding product, the method comprising:
- extruding a polymer core material to form a structural carrier;
- determining a desired notching pattern for notching the structural carrier along its length to form a notched structural carrier wherein a first plurality of specific regions have notches, wherein a second plurality of specific regions are relieved from having notches, and wherein the notched regions and relieved regions are arranged with respect to each other based on desired bending characteristics for a final coextruded product such that the final coextruded product conforms to a specific molding application;
- selectively notching the structural carrier in accordance with the desired notching pattern;
- and
- extruding a polymer seal material over the notched structural carrier to form the coextruded product.
A molding product, the product comprising:
- a structural carrier having notches along its length, wherein a first plurality of specific regions of the structural carrier have notches, wherein a second plurality of specific regions of the structural carrier are relieved from having notches, and wherein the notched regions and relieved regions are arranged with respect to each other such that consecutive notched regions are spaced apart at non-uniform intervals to provide desired bending characteristics for conforming to a specific molding application;
- and
- a polymer seal material over the notched structural carrier.
A structural carrier for use in a molding product, the structural carrier comprising:
- a structural carrier having notches along its length, wherein a first plurality of specific regions of the structural carrier have notches, wherein a second plurality of specific regions of the structural carrier are relieved from having notches, and wherein the notched regions and relieved regions are arranged with respect to each other such that consecutive notched regions are spaced apart at non-uniform intervals to provide desired bending characteristics for conforming to a specific molding application.
