Seals

Oil seals

Main Products

Oil seals are functional parts used to seal

NOK CORPORATION (NOK) was established as Japan’s first oil seal manufacturer in 1941. It manufactures sealing devices (oil seals, O-rings,
packings, etc.) used in a variety of machines, including automobiles. Through tireless research and development efforts undertaken since
its foundation, the company has successfully grown to be a leading company in the oil seal field.

oil. Composed of synthetic rubber, metalrings, and springs, they prevent oil fromleaking from gaps in machine shafts.
They also prevent the entry of dust fromthe outside.

O-rings

O-rings are O-shaped rubber ring packings. They are appropriately compressedby fitting into grooves of machinery, andprevent leakage of various fluids, including oil, water, air, and other gases.

Main applications
Automobiles, construction machinery, agricultural
machinery, railroad vehicles, steel mills, industrial
robots, aircraft, marine vessels, office machinery,home electronic appliances, etc.

Main applications
Automobiles, construction machinery, agricultural machinery, piping joints, water-proof cell
phones, etc.

Iron Rubber products
Iron Rubber (polyurethane elastomer),an intermediate product between rubber
and plastic, demonstrates excellent performance in resisting abrasion and absorbing
shock/vibration. We provide a wide rangeof products, including gaskets for machinery pistons and traffic signs & safety devices
that require superior durability.

NOK's history with oil seals is, in effect, Japan's history with oil seals
Producing Rubber Oil Seals

Technological Partnership

NOK Outpaces Competitors

Around the time when NOK was established,leather packings were commonly used in Japan forpreventing oil leaks from machinery. These packings did not provide stable sealing performance,
and automobile garages were always filled with thesmell of leaking oil. Responding to this problem,in 1942, NOK began producing rubber oil seals withsuperior sealing performance. In 1954, the company’s head office factory was constructed in Haneda,
and mass production was begun to enable the supply of products with uniform quality. We also began
conducting independent research into oil seals andannounced a lubricant principle with regard to thefriction and sealing of oil seals in 1959. Throughthese and other efforts, the foundation for NOK
was built into its present form.

In 1960, NOK began a new chapter througha technological partnership agreement with
Carl Freudenberg KG (CF) of the former West
Germany. Moreover, in the same year, the company started construction of its Fujisawa Plant
and expanded the production system by constructing other plants in Shizuoka, Fukushima,
and Kumamoto. NOK has successfully established a system for the stable supply of quality
products.
Through these measures, NOK has developed its foresight and technologies to create
products that accommodate market demand,
built a successful track record within and outside Japan, and developed into a leading oil
seal manufacturer in Japan.

In 1979, when only one Japanese automaker
had a production base in the United States,
NOK built a manufacturing plant in the country
ahead of others and began supplying oil seals
to local automakers. This achievement would
not have been possible without NOK’s outstanding technologies, stable supply, and the trust it
has built over the years.
Since then, we have established our production bases in such countries as Singapore,
China, Thailand, Indonesia, India, and Vietnam.
We have thus built stable supply systems tomeet the needs of our customers not only inJapan but around the world.

MEKTEC CORPORATION Electronic components
MEKTEC CORPORATION (MEK) was founded as a company responsible for the electronic components business of the NOK Group. MEK develops andmanufactures thin, lightweight, and super flexible electronic circuit boards called flexible printed circuits (FPCs). MEK keeps up its efforts for the researchand development of FPCs that are used for a variety of electronic devices, and aims to realize more convenient and comfortable living.

Single-sided FPCs

Main Products

FPCs with circuits on one side are

Double-sided FPCs

structured to best exhibit their thin andflexible characteristics. Durable against
repetitive bending, single-sided FPCs
can be mounted on moving parts andtake up little space. They are also
suitable for multi-dimensional wiring in
narrow gaps.

These have circuits on both sides.
Compared to single-sided FPCs, they
allow more complex wiring, andcontribute to downsizing and weight
reduction through the mounting ofparts on both sides. They can also be
used for various designs because they
are freely bendable.

Main applications
Automobiles, HDDs, digital cameras, media players,
game consoles, medical and healthcare devices, etc.

Main applications
Smartphones, digital cameras, automobiles, medical
and healthcare devices, etc.

Precision rubber andplastic components

Multi-layer FPCs

These FPCs have realized higher
functionality, smaller size, and lighter
weight through multi-layered circuits.
Integrated boards and cables contributeto downsizing, as they require noconnectors.

Endeavoring to be a Global Company that Supports an Electronic Society
Earliest Days of FPCs

In 1969, NOK concluded a technologicalassistance agreement on the manufacture ofelectronic circuits with Rogers Corporation of
the United States. MEK was founded on thisoccasion, and the full-fledged manufacture of
FPCs had begun. At that time, FPC technology
was a leading-edge technology that was not wellrecognized. This changed dramatically with thesubsequent release of the fully electronicallycontrolled single-lens reflex (SLR) camera, whichis recognized as an excellent product that has
made its mark on the history of cameras. Since
FPCs were adopted as one of the core electronicparts used in SLR cameras, they attracted theattention of engineers. Indeed, the practical use
of FPCs was a sign of what was to come in termsof new-generation electronics.
7

Realizing Flexural Resistance

Supporting the Ever-Evolving

Since FPCs were adopted for SLR cameras,
their research and development has madefurther progress, opening up more possibilities
for the products. In particular, it is noteworthy
that FPCs were adopted for computer harddisk drives (HDDs). The arms of HDD heads,
which read signals from disks that revolve at asuper-high speed, also operate at a high speed.
Therefore, FPCs used in the arms are required
to have flexural resistance exceeding 100
million bends. MEK has met this requirementwith its materials technology. MEK’s FPCs arehighly reliable and usable under very severe
conditions, thus garnering the full attention of
the computer industry.

Being key contributors to the downsizing
and weight reduction of electronic devices,
MEK’s FPCs now support everyday life throughout society, ranging from indispensable
smartphones to next-generation vehicles.
Also, MEK has introduced a global brand,“MEKTEC,” supplying a variety of FPCs globallyfrom its manufacturing sites and sales offices
around the world. MEK has been building asystem to respond to a variety of needs, frommaterial development to the manufacture of
FPC modules, in a flexible manner.
We will continue to pursue our goal of becoming
a global company to support an electronic-basedsociety with untiring efforts for technologicalinnovation and strict quality control.

FPCs are very thin films and therefore
require a special mounting process.
MEK not only manufactures FPCs alone,
but also fulfills requests for FPC module
units by mounting semiconductors,
microchip components, and connectors
on them.

Fitted inside HDDs and smartphones
or on their exterior, these products
are sealing parts that prevent theentry of water and dust . Utilizing thetechnologies fostered in development
and manufacturing processes, Mektron
also offers products with additional
waterproofing functionality and ananti-shock mechanism (protection) bymolding rubber or resin to FPCs.
