Just to build on Parik's assessment….
I agree that "Sandblasting" is just one option. It's typically used as a surface preparation step to remove surface oxidation before polishing.
A couple other more commonly used process to remove oxidation are chemical etching and media tumbling.
I 100% agree with Parik that, "It really depends on what process flow works for them. There is no one desired way to get to the end goal but there are options with different advantages and challenges."

Subject: Is Sandblasting Essential for Making Nitinol Stents?
Per Dr. Dr. Parikshith K. Kumar - Media blasting is a typical processing step leading up to electropolishing of laser cut stents. This is one option available in the manufacturing of braided stents. Other options may include braiding the stent with oxide free wire (e.g. straight annealed mechanically polished wire) and thereby forgoing the need for polishing altogether as long as there is no heat treatment involved. It really depends on what process flow works for them. There is no one desired way to get to the end goal but there are options with different advantages and challenges.

Subject: Is Sandblasting Essential for Making Nitinol Stents?
I'm seeking advice on whether sandblasting is a necessary step in the manufacturing process of Nitinol braided stents. I understand that sandblasting is essential before polishing in the laser cutting of stents.
How do the world's leading companies handle this process?
