Description

These parts involving:

1.Copper tube expanding, also known as swaging of copper tube. This is a process that involves increasing the diameter of a copper tube by compressing its walls with a specialized tool. This kind swaging of copper tube makes the tube fit snugly onto another component to ensure a secure and leak-free connection.

2. 2 step bending process that involves two distinct angles, typically performed with a tube bending machine. This technique is commonly used to create complex bends or shapes in copper tubing.

3. A twist angle, on the other hand, refers to the degree of rotation that occurs during the bending process. This is important to consider when designing or bending copper tubing. Too much twist can cause kinks or deformities in the tube that may compromise its integrity.
