Polished Metal Sleeves

 

Polished Metal Sleeves

One of our product line up is thin wall metal sleeve.  Thickness 0.1 to 0.3mm.
We can polish its surface up to Rz 0.1μm and less, same as JIS-‘01.
Much higher value of Rz is OK.
Also surface roughness and waves can be discussed.
The picture below is a polishsed Nickel seamless sleeve.

In this picture we can find dots of a surface stone plate,

but those dots are not reflected on the inner surface.

The outer surface is finer than the inner surface

Further polishing is possible on this outer surface.  We also polish stainless steel sleeves.

Our polishing range and specs are flexible.

We can offer various levels of polishing including limited area of polishing.

Cyridical Seamless Replica Mold for the Nano-imprint Stamper

I have been always suffering from a seasonal allergy at this time of year, and I have been spending my days enduring my runny nose and itchy eyes again this year.

The forecast suggests that more pollen is observed this year than average.

The range of pollen's diameter is from 10μm to several dozen μm. It is so fine that they are invisible for human eyes, but, they are spread into the atmosphere.

By the way, we have been introducing this so frequently on our blogs these days though, Dymco is focusing on the production of replica molds for applications such as nanoimprint molds.

This replica mold suggests replacing an expensive master roll by a "disposable" replica which is precisely duplicated from a master mold. The master mold has engraved patterns on its surface. They are several μm to several tens μm deep and wide, which are invisible to human eyes just like the pollen. It is a new technology that can protect the master mold from consumption or damage.

The "disposalable" replica duplicated from the master mold

・The shape of the master mold can be precisely duplicated. (seamless)

・Instability in the quality of the mold can be reduced by duplicating from the best master mold.

・The cost of duplication is reasonable compared to that of producing a new master mold - mass production is possible

Nickel sleeve by electro forming

Here we introduce how our nickel sleeves are made.

First we prepare for a mother roll.

This mother roll is placed in basin so that Nickel ions are accumulated by electrolytic deposition on a mother roll surface.  When accumulation reaches the required thickness, this Nickel sleeve is taken out from the mother roll.
 

Nickel sleeve-fomed process:
Mother roll →　Electrolytic deposition → Detached and separated

 This is completely seamless and a cylinder almost same as the mother roll.  These are unique features of Nickel sleeves that welded endless belts cannot compete.  Electrolytic deposition is being improved and heat restiveness is better than the conventional ones and  sometimes we do no find surface defects.
