In-Line Real-Time Surface Roughness Measurement of Insulated Wires and Cables and How Manufacturers Can Use It for Improved Product Quality and Increased Production Output

摘要

This paper discusses how surface roughness of an extrudate depends on extrusion processing conditions. Results from experimental test runs with varying barrel temperature, screw speed and pull tension are presented. A new in-line roughness measurement technology is introduced and its use in the production of insulated wires and cables is explored. This paper also discusses how real-time roughness monitoring can be used as an efficient tool in optimizing cable extrusion processes resulting in improved quality and increased production volume. This paper is applicable to manufacturing of all types of insulated wires and cables, from thin wires to consumer electronics cables, telecommunication cables and high-capacity power transmission cables.
