Rolling technology by RIKAZAI
Depending on the raw material being used, the thick material is first reduced to a thickness of about 1 mm using our newly-introduced warm-rolling mill, after which the metal plate is turned into foil by being passed repeatedly through the cold-rolling mill, which allows for precise rolling without oxidisation of the metal surface.
To a thickness of 0.001mm［1 micron］
A team of two works
in harmonious coordination
From Inserter to Receiver, again and again
This work requires intense concentration
The rollers are polished
after every few inserts
Making subtle adjustments to the roller spacing
Peeling off the ultra-thin foil takes special skill
『Feeling the thickness of the delicate foil』
This is how ultra-thin foil is made
