Core wire is a single end wire used as a mandrel, or place holder, during medical tubing extrusion. Once the tubing polymer has been extruded, the core wire (often a Silver Clad Copper or Tin Clad Copper wire) is then elongated to decrease the wire’s diameter. The final step of the process is sliding the wire out of its “sheathing,” and leaving a round tube for medicine delivery, guide wire/device insertion, or other technical applications.
The tubing of our Core Wire eliminates the potential for flaking and contaminating equipment or finished product, while being a cost-effective solution to demanding Medical industry needs.
Why Choose Stainless Steel Over Silver Clad or Bare Copper?
Our annealed stainless steel wire carries nearly identical physical properties to a Silver Clad or Tin Clad Copper wire. Elongations well exceed the 30% necessary in most extruded tubing applications, while our surface finish allows for adequate friction during the extrusion process.
As solid material, we’ve eliminated the potential for flaking and contaminating equipment or finished product, while greatly decreasing the production time to make custom sizes.
Our ELASTICORE® medical extrusion wire adds value to your medical tubing by:
- Reducing lead time
- Reducing cost
- Eliminating potential contamination
