Simulation of Coextrusion Process of Cladded Finned Tube by Plasticine

동시 압출법에 의한 핀형 튜브 Cladding 공정의 Plasticine 압출 모사

In this study an attempt was made to simulate the coextrusion process of the cladded finned tube manufacturing by extrusion of plasticine. The effects of the billet and the plate inserted between the ingot and extrusion die on the variation of clad thickness of the extruded tube were studied. The results showed that cladded tube with uniform thickness can be obtained by a proper combination of clad thickness of billet and the plate. The relative strength of the billet and clad materials did not affect significantly on the variation of the clad thickness of the extruded tubes.
