Process Makes Perfect – Melt Extrusion Saves Time and Money

Although commonly used in the manufacturing process of aerospace data cables, PTFE ram (formally known as PTFE paste extrusion) extrusion of inner conductors has a number of negatives. The nature of this process and its start-and-stop production method causes ram extrusion to have longer lead times, shorter average lengths leading to greater scrap.  Finally, the very nature of PTFE leads to problematic downstream process handling- cutting and stripping during connectorization as each cut may often need custom hand trimming.
