Abstract
A method of manufacturing a foam component includes generating, via a computer aided design (CAD) software, three-dimensional data corresponding to the foam component. The method further includes scaling, using the CAD software, the three-dimensional data to correspond to a preform. The preform is smaller than the foam component based on a scaling factor. The method further includes fabricating the preform from a thermoplastic elastomer and adding a foaming agent to the preform. The method further includes foaming the preform by exposing the preform to a target temperature for a target time via a heat generating device.
Claims8
A method for manufacturing a foamed sole with a target density for an article of footwear, the method comprising:
- determining a geometry of the foamed sole;
- determining the target density;
- determining a scaling factor corresponding to the target density;
- fabricating a preform of the foamed sole based on the scaling factor, via an additive manufacturing device;
- adding a foaming agent to the preform;
- and
- foaming the preform to expand the preform to match the determined geometry.
