Our Micro-Precision
Machining Supports Information Technology

We make micro-parts such as pins and tubes used in the
battery sections of mobile phones.
Using micro-precision technology, we have realized mass
production machining of detailed sections, a task that was
impossible using conventional cutting techniques. Backed
by this technology, our micro-parts have won general approval
and are widely used by IT manufacturers both in Japan and
throughout the world.
It goes without saying that this technology has made a
considerable contribution to cost reduction and compactization,
thereby accelerating the popularization of mobile phones.
Micro-parts represent a field that is helping to drive
Fuserashi forward in the 21st century. Such parts are employed
not just in mobile phones but also in a wide diversity of
IT-related products including information equipment and
audio/ video equipment, etc.
One method of tackling the reduction of C02 emissions,
which are a major cause of global warming, is to put HEVs
(Hybrid Energy Vehicles) into practical use. The on-board
batteries that provide power to these vehicles around the
world contain Fuserashi HEV-use parts.
We developed these HEV-use parts in-house by making use
of technologies such as cold pressing and cold forging.
At present, we are carrying out joint studies with our customers
concerning the choice of shapes, materials, etc., used for
these parts so that further rationalization of production
and higher battery performance can be attained. Moreover,
we are verifying the cost benefits of full-scale mass production
of these batteries. We will also continue conducting research
with the aim of making our batteries compatible with the
zero-emission vehicles (vehicles that reduce the environmental
load to virtually zero) that will be developed in the future
Ideal for battery- powered bicycles, cordless vacuum cleaners,
electrical tools, etc., batteries produced using Fuserashi's
technology are making an invaluable contribution to everyday
life and are helping to improve the environment as substitutes
for lead batteries.
Among the many attributes required of the buildings and
materials used in urban construction, the most important
factors are safety and executability.In particular, the
joints that secure the steel frames and beams, etc., used
in reinforced concrete construction can only be fixed in
place from one side. So despite the need for connection
work to be carried out with maximum safety and executability,
until now the only practical method has been welding. However,
because welding requires skilled technique, doesn't produce
uniform finishing, and has to be inspected using X-ray photography,
etc., it is not a particularly efficient method.
In order to overcome these problems, Fuserashi has made
it possible to execute joints from one side through the
use of one-side bolts, an established technique that even
people with little experience can perform relatively easily.
Using this technique brings many benefits including improved
vibration resistance of the joint sections, reduced execution
cost, shorter construction time, significant labor saving,
etc. At present, one-side bolt joining is being employed
in numerous locations for tasks related to urban infrastructure
such as strengthening bridges and preventing the collapse
of expressway side walls, as a joint technology that combines
both of the two vital factors of safety and executionability.
