An efficient lamination presses can rapidly provide both heating and cooling, as well as pressure to resin sheets to create a laminate end-product. Specifically, an efficient lamination press can comprise one or more components and apparatus that can apply uniform fluid pressure across one or more platens. The one or more platens, in turn, can flex about one or more contours in a layup assembly. For example, an exemplary platen can comprise a plurality of coupled platen extensions, which can flex or otherwise adjust about each other to help create flexibility in the platen, and thus, uniform pressure across a laminate assembly.

1. A lamination press configured to apply heat and uniform pressure to laminate assembly to rapidly and efficiently form a laminated product, comprising: an upper press component and a lower press component, each press component having a corresponding first or second flexible platen moveably coupled
1. A lamination press configured to apply heat and uniform pressure to laminate assembly to rapidly and efficiently form a laminated product, comprising: an upper press component and a lower press component, each press component having a corresponding first or second flexible platen moveably coupled thereto;one or more fluid actuators configured to pressurize one or more of the press components with fluid and apply uniform fluid pressure to one or more of the first and second flexible platens;wherein one or more of the first and second flexible platens are configured to move toward the other of the first and second flexible platens and apply substantially uniform pressure to a laminate assembly as one or more of the upper press component and the lower press component are pressurized; andone or more heat sources configured to heat the first flexible platen and the second flexible platen;wherein: at least one of the first flexible platen or the second flexible platen comprises a plurality of platen extensions that are flexibly coupled together; andthe plurality of platen extensions are configured to directly contact a surface of the laminate assembly to provide heat and pressure to the laminate assembly. 2. The lamination press as recited in claim 1, wherein the one or more fluid actuators comprises an air pump configured to pressurize the upper press component and the lower press component with air. 3. The lamination press as recited in claim 1, wherein the one or more heat sources comprises radiant heating elements positioned in the upper press component and the lower press component. 4. The lamination press as recited in claim 3, wherein the radiant heating elements comprise halogen lamps. 5. The lamination press as recited in claim 1, further comprising a plurality of linear fluid channels within the first flexible platen and within the second flexible platen. 6. The lamination press as recited in claim 5, further comprising a cooling source configured to cool the first flexible platen and the second flexible platen by pumping a cooling medium through the plurality of linear fluid channels. 7. The lamination press as recited in claim 1, wherein the first flexible platen and the second flexible platen are each comprise aluminum and have a thickness of between about ⅛ inch and about ½ inch. 8. The lamination press as recited in claim 1, wherein one or more of the first flexible platen and the second flexible platen comprises a plurality of ridges extending from a surface thereof. 9. A flexible platen for use in a lamination press for applying uniform pressure to a laminate assembly to form a unitary product, comprising: a plurality of platen extensions, each comprising a first surface, an opposed second surface, and a thickness extending therebetween;wherein: the plurality of platen extensions is flexibly coupled together pivotably, so that the first surfaces of the plurality of platen extensions comprise a substantially planar, flexible surface configured to apply uniform pressure directly to a surface of a laminate assembly;the flexible platen comprises part of at least one press component that is configured to press against an opposed press component comprising an opposed flexible platen; andthe flexible platen and opposed flexible platen cooperate to apply pressure directly to opposing surfaces of the laminate assembly. 10. The platen as recited in claim 9, wherein each platen extension in the plurality is configured to pivot or flex relative to each adjacent platen extension. 11. The platen as recited in claim 9, wherein the thickness of each platen extension comprises between about ⅛ inch and about ½ inch. 12. The platen as recited in claim 9, wherein each platen extension comprises aluminum. 13. The platen as recited in claim 9, further comprising a plurality of linear fluid channels extending linearly through the thickness of each platen extension of the plurality of platen extensions. 14. The platen as recited in claim 9, further comprising a seal extending between adjacent platen extensions of the plurality of platen extensions. 15. A method for applying heat and pressure to a laminate assembly to form a unitary product comprising: placing two or more layers between opposing platens of a lamination press, wherein at least one of the opposing platens comprises a plurality of flexibly coupled platen extensions configured to provide heat and pressure directly to the laminate assembly;pressing the laminate assembly together by applying substantially uniform fluid pressure across at least a majority of the opposing platens to close a distance between the opposing platens, wherein at least two of the platen extensions pivot relative to each other during pressing;heating the laminate assembly by heating the opposing platens; andcooling the laminate assembly by cooling the opposing platens of the laminate assembly. 16. The method as recited in claim 15, wherein the substantially uniform fluid pressure causes one or more of the opposing platens to flex about one or more contours in one or more surfaces of the laminate assembly thereby applying substantially uniform pressure across the one or more surfaces of the laminate assembly. 17. The method as recited in claim 16, wherein flexing of the one or more opposing platens comprises two or more platen extensions of one or more of the opposing platens pivoting relative to each other about a contour in the laminate assembly. 18. The method as recited in claim 15, further comprising pumping cold water through one or more linear fluid channels extending within and along the length of one or more of the opposing platens. 19. The method as recited in claim 15, wherein heating the opposing platens comprises radiating the opposing platens with one or more radiant heating elements. 20. The lamination press as recited in claim 1, wherein the platen comprises a plurality of joints that enable the plurality of platen extensions to pivot relative to each other. 21. The lamination press as recited in claim 20, wherein the plurality of joints comprise a tongue and groove configuration.
