Abstract
A method of manufacturing a product, dispenses, through a tool with an aperture sized to match an overall perimeter of a product, a molten thermoplastic resin. The tool generates a plurality of strands through the tool aperture while maintaining the plurality of strands within the overall perimeter of the product. The strands are buckled by resisting a flow of the plurality of strands. The buckled strands intersect as a unitary non-woven body in a shape of the overall perimeter of the product.
Claims9
A method of manufacturing a vehicle seat cushion, comprising:
- providing a tooling plate on a vehicle seat manufacturing system, wherein the tooling plate is selected from a plurality of tooling plates, based on a desired shape of a vehicle seat bottom cushion, wherein the tooling plate is replaced with another tooling plate according to the desired shape of the vehicle seat bottom cushion;
- dispensing, through the tooling plate, a plurality of strands of a molten thermoplastic resin, wherein the tooling plate is a 3-dimensional shaped mold comprising a plurality of cooling passages and an aperture formed through the three dimensional shaped mold of the tooling plate, and wherein the aperture of the tooling plate is of a shape that matches a contour of an overall perimeter of the vehicle seat bottom cushion;
- facilitating a flow of the plurality of strands through the tooling plate while restricting the flow of the plurality of strands within the contour of the tooling plate that matches the overall perimeter of the vehicle seat bottom cushion and shaping the plurality of strands into the contour of the tooling plate;
- and
- passing a coolant through the plurality of cooling passages after shaping the plurality of strands into a meshed shape corresponding to the shape of the contour of the tooling plate, wherein the plurality of cooling passages extends towards the aperture of the tooling plate to cool the plurality of strands within the contour of the tooling plate,
- wherein the plurality of strands is buckled by resisting the flow of the plurality of strands within a profile defined by the contour of the tooling plate, the buckled strands intersecting as a unitary non-woven body in a shape of the overall perimeter of the vehicle seat bottom cushion.
