To increase strength and toughness of metals.A technique used for metal optical frame, medical devices and fashion accessories.
Swaging is used to beat and stretch round wire into any shape under room-temperature conditions without scraping it.This technique stretches thick wires into thin ones, so it is useful in producing integral pieces with both thick and thin parts.
To form components, using metal mold. Accurate dimensions and configuration can be created by the computerized pressing processes.

To form a shape of rim wires that hold the lens of eyeglass, various configuration can be made by 3D bending processes.
Round wires are bent in three dimensions and coiled into complex shapes using original technologies.
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.
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.
Precision metal processing is a cutting technology that uses numerically controlled (NC) lathes. It is used to produce small-diameter parts from 1mm to 20mm.
This technology uses laser processing equipment to cut and form holes. Laser cutting delivers smooth cut lines even with the most complex shapes.
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.
An advanced technology developed in collaboration with the Joining & Welding Research Institute of Osaka University.Microscopic irradiation allows fine welding of extremely small components.
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 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.
This process technology is an environmentally friendly direct-marking method that uses no ink or printing materials. Marking is contactless, preventing degradation of materials.
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.
A coating technique that electrically applies to protect the product.
