挤压复合材料可以提供很大的优势。本文研究了在单一生产步骤中制造混合金属型材的方法。使用舷窗模具，从而生产具有挤压缝的型材。沿着接缝可以看到混在一起的材料。采用有限元方法对挤压过程进行了模拟，研究了模具和焊接腔内的材料流动情况，了解了焊缝缺陷产生的原因。
Extrusion of composite materials can offer big advantages. In this work the manufacturing of a hybrid metal profile in a single production step was investigated. A porthole die was used, thus producing profiles with extrusion seams. Along the seams a material mix up was visible. The extrusion process was simulated with the Finite Element Method to investigate the material flow in die and welding chamber in order to understand the cause for the defects at the seams.
