Optimization analysis on gap size of molding for Pb-GF composite wire

Abstract

Under the condition of equal flow, the maximum and minimum theoretical values of gap size were studied and an estimation equation was established for the clad extrusion of the brittle core cladded by plastic metal materials. The results show that the gap size is a key parameter for the continuous clad extrusion and the molding speed. Its maximum value (H_max) is 0.24 mm and the minimum one (H_min) is 0.12 mm. At a gap size of 0.18 mm, the maximum of metal extrusion per unit of time and the optimal coating speed can be obtained.
