Recently, it
is increasing for us to provide moulds for nanoinprint with micro patterned
surface.
Thickness of sleeve is around 0.05mm~0.3mm and
materials are Nickel or SUS.
A process
to make a master mould, sleeve is pressed fit onto an axis and polish as mirror
surface.
After the sleeve is polished, it is curved
micro pattern on the surface.

However, this means needs high precision machine tools and takes much time.
Also, the master moulds have lifetime so it
is necessary to have a few moulds for mass production.
We have invented a new solution to make
copy mould which is totally same as its master with transfer the micro pattern
twice.
It does not cost like making new moulds by
curving.
Example of micro patterned thin metal sleeve
The picture is an example but we could have smaller pattern recently.
We coat electroless nickel plating on nickel sleeve first and curve after press fit the sleeve onto an axis.
The patterned sleeve is used with pressed fit
onto an axis of mass production machine.
To press fit, a specific skill is necessary so
we usually manufacture the axis as well.
