What is "shibo" ?
"Shibo" is the Japanese term
for the crepe or pebbly pattern effect seen in textiles
and in some leathers.The term "Shibo" has been used in
Japanese textiles since approximately the 12th
century,and is most commonly seen today in "Shibori"
crepe textiles. The shibori pattern is achieved by
rubbing, crimping, and gathering a textile or
leather during production or tanning. The Japanese
plastics industry has developed rapidly since 1945, and
new leather texturing methods to be applied in plastics
molding have been desired to further increase product
value. Tanazawa hakkosha identified this need early on.
Leather texturing processes prevent weld lines and sink
marks and also eliminate secondary processing
requirements. Highly decorative texturing precesses have
become an essential element of many plastics molding

reinforcement and safety by reducing slippage.
-The natural-like texture of
raw leather, natural wood, and textiles can be
accurately reproduced, creating materials with high
quality finish and feel.
-Fine patterns can also be
reproduced. The etching depth can be freely controlled
to obtain a special effect.
-Designs can be enlarged and
reduced. Virtually almost metal surfaces can be etched
-A glazed, semi-glazed, or
matte finish can also be imparted as desired.
-Multiple patterns can be
imparted to a signal metal surface.
-Joint-free processing is
possible even in complex 3D sections, assuring a more
aesthetically pleasing effect.
What is etching ?
Etching refers to a group of techniques whereby a
design drawn or applied to the surface of a metal or other
material using a corrosion resistant agent (e.g., paint)
protects the covered design area while an acid or other
corrosive agent engraves the remaining surface metal.
Etching processes are particularly useful in processing
plastic moldings with 3D surface patterns due to the
economy, consistent quality, and processability offered by
etching. Because etching is essentially a process of
chemically engraving the surface, it is also referred to as
"Chemical engraving". This process is also able to impart
much finer patterns and designs than can be achieved with
mechanical engraving processes. Etching is widely used for
texture processing of metals and rolls, in the production of
relief and intaglio printing plates, printed circuit board
wiring, and other applications.
Product textures are determined from the dual
perspectives of functionality and creative design after
accurately identifying product needs. Years of
experience and expertise direct our consulting effort,
while sampling is the basis for a detailed check of
needs and results. The final result is a product that
better meets all requirements.
