Post Treatments for black oxided parts

Letter 10033

I'm interested in learning about how black oxide parts are finished-off.

From what I understand some companies use a synthetic vinyl or rubber material (similar to pencil erasers) to smooth the edges of finished parts. I'd like to know more about this.

Is this a common practice used throughout the industry or does it just pertain to certain types of applications?

I have never heard of this. What kind of parts are you referring to?

Hi, John. I agree with Tom. I have never seen anything like that. Please tell us what kind of edges of what kind of parts would benefit from this kind of process. Thanks.
