Produce More Precise, Distortion-Free, and Repeatable Microbore Medical Tubing

April 10

Understanding Hot Die 

The gap between the hot die face and the initial contact of cooling process water is known as the hot gap in microbore tube processing. This distance can directly affect the tube OD, wall thickness, ovality, and material properties. In this webinar, you will gain a thorough understanding of hot die gap and how it impacts your ability to produce a repeatable process for making the most precise microbore medical tube. 

You’ll learn: 
- The definition of hot gap and how it impacts your process. 
- How material properties can be affected by the hot gap. 
- How tube sizing and stability can be affected by the hot gap. 
- Why the hot gap is a critical validation point. 
- A new and unique method of adjusting the tank with improved precision. 

The Importance of Puller Belt Gap 

Most processors fully understand the importance of the puller in making precision medical tubing. It is widely known that it requires precise speed control to pull the tube through the cooling medium at a consistent speed to attain optimum OD, ID, and wall tolerances. But, a lesser known variable is the gap between the belts or pinch rolls on the puller. In this portion of the webinar, you’ll learn why belt gap is a critical consideration in eliminating variable slippage and tube distortion. 

You’ll learn: 
- How belt gap settings can mean the difference in processing a round versus a partially distorted tube. 
- How belt gap can affect slippage between the belts and the tube causing variable pulling speeds. 
- How belt material and belt types affect slippage and the potential for bowing or twisting of the tube, and particulate generation. 
- Why belt gap should become a validation point and a novel solution.
