Old post share.
Diffusion welcome.

Although our company that is usually remodeling a motorcycle, we spend a technique seriously and make a duralumin cutting ballpoint pen.
The name of the ballpoint pen “is MechaSEA”.

We have experimented to see if two color alumite can be made.
We can not think about the order of cutting process unless we confirm it now.
So, we did homemade alumite.
We did it using the temperature controller and electric stove which we made before.

We used dilute sulfuric acid, dye, sealant, lead electrode and pure aluminum wire at that time.
That is “Let’s alumite kit” I bought at Yahoo auction.

The way to do it is written in detail in the manual. Great.

I not made black dye before.
So, we compounding newly.

Process is degreasing → energization in sulfuric acid → water → dye → water → sealing agent → water.
The electricity is OK with a battery battery charger.

This time, we wanted to know if we could do two color alumite.
So, we cut off the alumite part of the item on which alumite is already done with milling cutter or belt cutter and do the alumite.

When I write more than this, it will be long.
It will continue to the next…

Araki F Machine seriously introduced technology and made it.
It’s all made with cutting of the aluminum.
It’s extremely mechanical ballpoint pen, MechaSEA.
