Method and tool for manufacturing a vehicle interior trim part, as well as a vehicle interior trim part
The present disclosure relates to a method for manufacturing a vehicle interior trim part with at least one functional and/or decorative element. The functional and/or decorative element can be additively manufactured from a thermoplastic material and include a structured surface. The present disclosure further relates to a tool including a depositing unit and a receiving device with a receiving surface which is curved or at least partly structured.
1. A method for manufacturing a vehicle interior trim part which comprises a carrier part and a plastic element, comprising the following steps:
providing a tool comprising at least one depositing unit for depositing a fluid, curable plastic and a receiving device with a receiving surface for receiving a carrier part with a front side and with a rear side, wherein the at least one depositing unit and the receiving device are movable relative to one another;
applying the carrier part onto the receiving surface in a manner such that the front side of the carrier part at least regionally lies on the receiving surface;
at least regionally depositing the fluid, curable plastic onto the carrier part surface in a layered manner, such that at least one plastic element which is materially connected to the carrier part is generatively manufactured; and
curing the plastic,
wherein the receiving surface is structured at least regionally and the fluid, curable plastic is deposited at least regionally directly onto the structured receiving surface.
2. A method according to claim 1 , wherein an adhesive is deposited onto the carrier part surface at least regionally, before the depositing of the fluid, curable plastic.
3. A method according to claim 1 , wherein the receiving surface is structured at least regionally and for forming the plastic element which is connected to the carrier part, the fluid, curable plastic is deposited at least regionally onto an outer edge of the carrier part and onto the structured receiving surface in a manner such that the plastic element comprises a structured surface which corresponds to the structured receiving surface.
4. A method according to claim 1 , wherein the fluid, curable plastic is deposited in a layered manner by way of an additive manufacturing method.
5. A method according to claim 1 , wherein the fluid, curable plastic is deposited by a FDM method.
6. A method according to claim 1 , wherein the fluid, curable plastic is deposited in droplets or strands.
7. A method according to claim 1 , wherein the plastic element forms a frame which at least partly peripherally edges the carrier part and/or wherein the plastic element is arranged on the rear side of the carrier part.
8. A method according to claim 1 , wherein the structured receiving surface comprises deepenings in the form of at least one of troughs, grooves and furrows.
9. A method according to claim 8 , wherein the at least one of troughs, grooves and furrows have depths in a range of 10 μm to 500 μm.
10. A method according to claim 1 , wherein the fluid, curable plastic is deposited in a layered manner by way of an additive manufacturing method at least regionally directly onto the structured receiving surface.
