  • Method for producing a foam body having an internal structure
    Patent number: 10946569
    Abstract: A method for producing a foam body (10) having an internal structure (100, 200, 300), comprising the steps: I) selecting an internal structure (100, 200, 300) to be formed in the foam body (10), the structure comprising a first polymer material; II) providing a foam body (10), the foam body (10) comprising a second polymer material which is different to the first polymer material; III) injecting, by means of an injection means (20), a predefined amount of a melt of the first polymer material or a predefined amount of a reaction mixture (30, 31, 32) which reacts to form the first polymer material at a predefined location inside the foam body (10), corresponding to a volume element of the internal structure (100, 200, 300); IV) repeating step III) for further predefined locations inside the foam body (10), corresponding to further volume elements of the internal structure (10), until the internal structure (10) is formed.
