Abstract
A method for determining the dimensions of plunger blank for die casting machines based on the
strength calculation of the plunger simultaneously affected by force loads, high temperature and friction forces is
proposed. The calculation of the minimum permissible wall and bottom thickness of the plungers having different
external diameters is made on the bases of the obtained results in case when the plunger is made of a heat and wear –
resistant volumetric nanostructured material of Cu-Al-C-O system.
