Method for producing a composite profile

A method for producing a composite profile extending in a longitudinal direction, comprising

• providing a first profile part extending in a longitudinal direction, made from a first plastics material, with a profile region, wherein the profile region of the first profile part is produced from a second plastics material that is thermally plasticizable at a first temperature T1,
• providing a second profile part extending in a longitudinal direction, which is produced from a material that is not thermally plasticizable at the first temperature T1, wherein the second profile part has a receiving structure formed along the longitudinal direction of the second profile part, to which the profile region of the first profile part is connectible by positive engagement,
• bringing the profile region of the first profile part into contact with the receiving structure of the second profile part,
• plasticizing the second plastics material of the profile region of the first profile part by heating to the first temperature T1 and
• deforming the plasticized second plastics material of the profile region of the first profile part while forming a positive engagement between the profile region of the first profile part and the receiving structure of the second profile part, wherein the receiving structure has a geometry that remains substantially unchanged during formation of the positive engagement.
