A new structure named covering type for the semi-hollow Al-profiles was present. through a common actual case, the determination of structure parameters was introduced in detail. Mainly including the arrangement of portholes, the structure design of chamber and the selection of bearing. The method of checking the die strength was introduced. According to the extrusion results, the structure of the traditional solid die and the covering type structure were compared. The characteristics of the latter structure were simple and easy to process. The practical application shows that the new die structure can enhance the die life, improve the production efficiency and reduce the cost. The high precision and the surface brightness of the profiles were obtained. The structure is worth promoting. The aim is to provide reliable data and reference for the further research and development on the structure for semi-hollow Al-profiles.
