Finite Element Simulation of a Porthole Die Extrusion Process for Manufacturing Aluminum Heat Radiation Pipe

알루미늄 방열 파이프의 생산 목적의 포트홀 금형 압출공정의 유한요소해석

We carry out non-steady state finite element simulation of a porthole extrusion process for manufacturing a radiation pipe under isothermal assumption. It is assumed that welding takes place at the moment that the material contacts the plane of symmetry. Welding phenomena are revealed by observing the contacting mechanism of the material passed through the portholes. It is emphasized that mesh density control and intelligent remeshing during welding process govern the solution accuracy and the program applicability. AFDEX 3D is employed.
