A Pinnacle of
Technology and Quality

Products produced by
Sabae's technology

Sabae technology

Sabae is full of traditional making
and one of Japanese leading technology
industrial city:
eyeglasses that have
the largest production share in Japan,
Echizen lacquerware,
which accounts for 80% of
the domestic production share of
lacquerware for business,
textile of Sabae, known as the center of
textile kingdom FUKUI.

Sabae has become a major
production area that produces
about 90% of eyeglasses
frames manufactured in Japan by
the success of world's first
productization of eyeglasses frame
made of titanium, establishment
of mass production system,
improvement of quality and
design and planning of
internationalization strategy.

In recent years,
Sabae aims to revitalize
it’s industry by trying to expand
into different fields
with our advanced
processing technology.


Precision special processing
of hard-to-work materials
such as titanium


production and small
lot production


Technology utilization
to many fields like as
medical industry

Round wires are bent in three dimensions and coiled into complex shapes using original technologies.

Precision Machining

In precision cutting, metals are processed using lathes, cutting equipment and dedicated processing machinery. Parts with diameters as small as 1.6mm can be processed using this approach.

video image

In this technology, metal is cut using dedicated processing equipment. It is applied to serve a wide range of applications, including medical components, painting equipment and industrial equipment requiring high-precision suction nozzles.

Laser cutting
This technology uses laser processing equipment to cut and form holes. Laser cutting delivers smooth cut lines even with the most complex shapes.

Water-jet cutting
This technology uses nothing but jets of super-pressurized water to cut soft, flat materials into the desired shapes. NC is used to cut even complex shapes with high precision.


Laser micro welding

An advanced technology developed in collaboration with the Joining & Welding Research Institute of Osaka University.Microscopic irradiation allows fine welding of extremely small components.

video image

In this technology, laser light is focused on metal work pieces to perform local joining. Unlike welding with a soldering iron, no flame is used. Oxidation is thus eliminated, reducing postprocessing after welding.

Ion plating, Electro Corting
Ion plating is a technology in which the surface of a titanium alloy or the like is coated under vacuum conditions. This processing makes the surface of the metal resistant to scratches, abrasion and tearing, enhancing corrosion- and weather-resistance.

Laser marking
This process technology is an environmentally friendly direct-marking method that uses no ink or printing materials. Marking is contactless, preventing degradation of materials.

Color laser process
A nanometer-level oxidized film is formed on the surfaces of metals such as titanium. The oxidized film reflects incident light to cause interference, generating a wide variety of colors on the surface.
