Title: Enhancements to Downstream Extrusion Water and Vacuum Tanks to Facilitate a Higher Level of Precision and Repeatibility.

Description:

Micro-bore tubing used for medical applications continues to require ever tighter tolerances and more consistent properties, leading to controlling more of the variables, which typically have been left to the operator.  The feature we will discuss in this presentation will allow the extrusion process to become more of a “science,” and eliminate the “art” which is difficult to repeat and validate.

Type: Pipe, Profile & Tubing

Abstract:

Micro-bore tubing used for medical applications continues to require ever tighter tolerances and more consistent properties leading to controlling more of the variables, which typically have been left to the operator.  

With water and vacuum tanks, the last of these variables to be totally controlled is the linear movement of the tank position in relation to the hot die.  This hot gap distance is now being recorded, but with totally manual controls (hand wheel).  But, as I will discuss in this conference, with the integration of a servo-driven linear actuator, this can be totally automated, and thus far more repeatable.  This is obviously a very important factor in validation, as this can affect the initial heat transfer and draw down, which can affect material properties.

With these simple updates, the extrusion processing of micro-bore medical tubing can be far more repeatable, which will lead to tighter tolerances and more repeatable and scientific end-results.
