Driven by the trend of industry 4.0, most industries began to introduce automation equipment. The automatic solder machine has also become a hot topic in the hearts of major bosses i
MORE+There are many factors that affect extrusion pressure, such as deformation disturbing force, deformation degree, external friction state, shape and size of die, angle of die, extrusi
MORE+In the process of extrusion, due to the friction between the inner wall of the extrusion barrel and the die section, the metal flows unevenly, which makes the middle metal flow faste
MORE+The non-uniform flow of metal has a great influence on the quality of products, which is mainly manifested in the non-uniformity of microstructure and properties before and after ext
MORE+When die angle a increases, the height of dead zone increases and the friction between metal flows increases. When die angle a = 900, the metal flow is the most uneven. Therefore, th
