The purpose of the study of Teflon 6 extrusion, sometimes referred to as paste extrusion, for insulating wire with Teflon was to determine the effect of each of the operating variables in the quality of the wire insulation. The die design, guide tip clearance, and the oven temperatures were found to be the most critical variables. For optimum machine performance the ram displacement rate and the wire speed should be controlled as accurately as possible. The extrusion process in its present stage of development is a suitable means for the commercial production of wire insulated with Teflon. It enables the use of the excellent properties of the Teflon insulated wire in many commercial applications.
