Yes, those imperfections of the Aluminium on Todd's headband is indeed correct.
There is a story behind it though, mid-way in our production our Anodizing guy decided to go rogue. The finished parts weren't dark enough and for some reason he was not able to rectify it.
We were left with some inventory that was fair but far from perfect and as a small Manufacturer, we couldn't afford to scrap it. Eventually, we did find a reliable Anodizing company and have been working with them since December albeit, they are interesting to deal with as well.
This leads me to believe either there is some money to be made in the Anodizing industry or the entire industry has undercut itself beyond sustainability.
Furthermore, we made some changes to our tool-paths as well and have added an additional facing operation on all sides to improve the surface finish without needing additional processes like brushing or sand-blasting. This may seem like something to do since the beginning but since we don't have a 5-Axis that we own, it adds more machining time and lowers our output even more. Every single part is made in-house.
We also have transitioned from 3D Printed Earcups to full Injection Earcups. Again, to improve our production rates so we can focus on things that are more delicate and intolerant.
Anyway, I do take the responsibility but just wanted to share why. With vertical integration although QC is in our hands, it is challenging to be this stringent at this price point especially when you are running out of Capital.
