Analysis of product defect made by continuous metal extrusion

Continuous metal extrusion may be used to produce the external conductor of coaxial cable and outer sheath of optical fiber cable and telecommunication and signal cables for railway application. The method features seamless and water tight product, high utilization of materials, high production speed and low production cost. This articles makes a though analysis on the quality of raw materials, pre treatment of semi finished product, extrusion process, die construction and die adjustment in a view to remove the quality defects associated with continuous metal extrusion.
