What is the reason for the low pressure of the aluminum profile extrusion machine?
During the extrusion process, the extrusion force is mainly affected by deformation resistance, processing rate, ingot length, die angle, extrusion speed, friction conditions, extrusion cylinder temperature and other factors. First, determine whether there is a problem with the hydraulic pump. If not, check the relief valve and tighten the pressure adjustment handwheel. Manually open the relief valve spool to see if there is pressure. The pressure should be set to 21Mpa.
