Description

Wire coating extruders are often asked to handle several polymers and/or a wide range of operating conditions in production. Selecting the proper screw to optimally handle the requirements set forth is important to maximizing performance and profitability. Screws over the years have evolved and today’s barrier screws are widely used, but the simpler screws of the past still fit well in some applications. This paper covers screw and extruder performance features for many of today’s wire and cable applications.
