chip card, and an injection molding device for the implementation of the process, wherein a mold in the injection molding device includes a minimum of one mold space and mold parts which are movable in relation to each other, whereby: a first injection nozzle is provided for injecting a first plastic material into a first mold compartment in the mold space; a second injection nozzle is provided for injecting a second plastic material into a second mold compartment in the mold space, and; in a preferred embodiment, the first injection nozzle is positioned vertically to the second injection nozzle. ## Claims ### Claim 1 A process to manufacture a chip card by injecting a molten plastic material into a mold and subsequently cooling down the plastic material, comprising the steps of: injecting a first plastic material into a first mold compartment while a second mold compartment is closed off with a slide gate; moving the slide gate that closes off the second mold compartment from the first mold compartment out of the mold space; and while maintaining the mold and the injected first plastic material stationary, injecting a second plastic material into the second mold compartment. ### Claim 2 (depends on 1) A process according to claim 1, wherein said injecting steps comprise the first plastic material and the second plastic material being injected at right angles towards each other into the corresponding first mold compartment and the second mold compartment, respectively. ### Claim 3 (depends on 1) A process according to claim 1, wherein the second plastic material injecting step comprises injecting the second plastic material into the second mold compartment after the first plastic material injected into the first mold compartment has shrunk. ### Claim 4 (depends on 2) A process according to claim 2, wherein the second plastic material injecting step comprises injecting the second plastic material into the second mold compartment after the first plastic material injected into the first mold compartment has shrunk. ### Claim 5 (depends on 1) A process according to claim 1, wherein the second plastic material is shrunk after injection, with its border surfaces contacting a first body formed by the first plastic material in such a manner, that the first body is held positively interlocked by the second plastic material forming a second body. ### Claim 6 (depends on 2) A process according to claim 2, wherein the second plastic material is shrunk after injection, with its border surfaces contacting a first body formed by the first plastic material in such a manner, that the first body is held positively interlocked by the second plastic material forming a second body. ### Claim 7 (depends on 3) A process according to claim 3, wherein the second plastic material is shrunk after injection, with its border surfaces contacting a first body formed by the first plastic material in such a manner, that the first body is held positively interlocked by the second plastic material forming a second body. ### Claim 8 (depends on 1) A process according to claim 1, wherein said moving step comprises simultaneously with an outward movement of the slide gate, moving at least one additional tool part towards the mold space. ### Claim 9 (depends on 2) A process according to claim 2, wherein said moving step comprises simultaneously with an outward movement of the slide gate, moving at least one additional tool part towards the mold space. ### Claim 10 (depends on 3) A process according to claim 3, wherein said moving step comprises simultaneously with an outward movement of the slide gate, moving at least one additional tool part towards the mold space. ### Claim 11 (depends on 5) A process according to claim 5, wherein said moving step comprises simultaneously with an outward movement of the slide gate, moving at least one additional tool part towards the mold space. ### Claim 12 (depends on 1) A process according to claim 1, wherein said second plastic material injecting step comprises the step of injecting the second plastic material in correspondence with the direction of movement of the slide gate relative to the second mold compartment. ### Claim 13 (depends on 2) A process according to claim 2, wherein said second plastic material injecting step comprises the step of injecting the second plastic material in correspondence with the direction of movement of the slide gate relative to the second mold compartment. ### Claim 14 (depends on 3) A process according to claim 3, wherein said second plastic material injecting step comprises the step of injecting the second plastic material in correspondence with the direction of movement of the slide gate relative to the second mold compartment. ### Claim 15 (depends on 5) A process according to claim 5, wherein said second plastic material injecting step comprises the step of injecting the second plastic material in correspondence with the direction of movement of the slide gate relative to the second mold compartment. ### Claim 16 (depends on 8) A process according to claim 8, wherein said second plastic material injecting step comprises the step of injecting the second plastic material in correspondence with the direction of movement of the slide gate relative to the second mold compartment. ### Claim 17 (depends on 1) A process according to claim 1, wherein the slide gate moving step comprises bringing the slide gate into a first position, in which it closes the first mold compartment off against the second mold compartment completely, and is then moved into a second position, in which the slide gate, which further comprises a cavity shaper, creates a recess in a mini chip carrier to be formed in said second mold compartment during said second plastic material injection step. ### Claim 18 (depends on 2) A process according to claim 2, wherein the slide gate moving step comprises bringing the slide gate into a first position, in which it closes the first mold compartment off against the second mold compartment completely, and is then moved into a second position, in which the slide gate, which further comprises a cavity shaper, creates a recess in a mini chip carrier to be formed in said second mold compartment during said second plastic material injection step. ### Claim 19 (depends on 3) A process according to claim 3, wherein the slide gate moving step comprises bringing the slide gate into a first position, in which it closes the first mold compartment off against the second mold compartment completely, and is then moved into a second position, in which the slide gate, which further comprises a cavity shaper, creates a recess in a mini chip carrier to be formed in said second mold compartment during said second plastic material injection step. ### Claim 20 (depends on 5) A process according to claim 5, wherein the slide gate moving step comprises bringing the slide gate into a first position, in which it closes the first mold compartment off against the second mold compartment completely, and is then moved into a second position, in which the slide gate, which further comprises a cavity shaper, creates a recess in a mini chip carrier to be formed in said second mold compartment during said second plastic material injection step. ### Claim 21 (depends on 8) A process according to claim 8, wherein the slide gate moving step comprises bringing the slide gate into a first position, in which it closes the first mold compartment off against the second mold compartment completely, and is then moved into a second position, in which the slide gate, which further comprises a cavity shaper, creates a recess in a mini chip carrier to be formed in said second mold compartment during said second plastic material injection step. ### Claim 22 (depends on 12) A process according to claim 12, wherein the slide gate moving step comprises bringing the slide gate into a first position, in which it closes the first mold compartment off against the second mold compartment completely, and is then moved into a second position, in which the slide gate, which further comprises a cavity shaper, creates a recess in a mini chip carrier to be formed in said second mold compartment during said second plastic material injection step.
