Sales of processed (with etching, press and laser) stainless steel parts
Sales of cobalt-chrome electrolysis/polishing liquids
Name & Brand of the Products, etc.
Aspects and/or features of the product Using our expertise in surface treatments of stainless steel as base technologies, we add functionality and artistic quality to stainless steel products. We can solve various problems based on electrolytic coloring treatment developed on our own and electrolytic polishing for which we have been reputed for a long time. Although we may primarily be characterized as an R&D enterprise, we can consistently provide high functionality and quality products via a quality control system accredited with ISO9001.
Information of the main materials, costs and filed of use
Products or parts name Stainless steel with black-colored appearance, Super Black
Products or parts description Black coloring of stainless steel, different from coating or plating, is achieved by growing an oxidized membrane on the surface of stainless steel.
Features Black coloring is applied to super-thin components such as 0.015-mm thick etching sheets and precision-processed camera parts for preventing reflections of light. Since the thickness of the surface membrane is less than 1 micrometer, even the toughest tolerance conditions can be cleared. The membrane is heat resistant and can accommodate reflow soldering.
Field of use Reflection prevention treatment of light shielding plates in the camera module of cell phones, in digital cameras, projectors etc.
Products or parts name Decorative technology for stainless steel products, Piano Black
Products or parts description Providing sheen like urushi lacquer's that is impossible with plating or coating! Mirror-surfaced black stainless steel
Features Superior decorative treatment that can provide beautiful, deep black appearances while preserving the metallic feels of the mirror surface. Leaving metallic feeling of mirror surface as is, we gave our additive decoration of velvety black treatment for its good aesthetics. Satinless electro coloring appearance can appeal the good finish in preserving of those basic materials, which can not materialized by ordinal painting or coating methods.
Field of use Decorative treatment added to the chassis of audio-visual and mobile devices
Products or parts name Super Black + laser marking
Products or parts description Markings with superior anti-corrosiveness and anti-weathering which are resistant to corrosion, fading and peeling
Features By applying lather markings to stainless steel parts treated with our Super Black processing, highly-contrasted and textured markings that are uniquely different from printed ones can be realized. Since these markings are applied to an inorganic oxidized membrane, they can weather outdoor conditions.
Field of use Decorative treatment of name plates, markings for traceability (bar codes etc.) and information home appliances
Products or parts name Stainless steel black coil (stainless steel with colored appearance)
Products or parts description A new material endowed with varieties of functionality such as prevention of reflected light, enhanced appearance as a quasi-exposed component and enhanced anti-corrosiveness
Features Black-colored stainless steel coils are being developed. This product's surface is treated with our proprietary electrolytic coloring technology to clad it with a Super Black precision oxidized membrane with less than 1 micrometer thickness. This technology is to be applied to SUS coils with 0.05 to 0.4 mm thickness and up to 300 mm diameter.
Field of use Exterior components of audio-visual, communications and IT equipment
Products or parts name Stainless steel mirror-surfaced coil
Products or parts description Coil made of stainless steel thin plate treated with mirror polishing
Features SUS coils with 0.2 to 0.3 mm thickness and up to 600 mm diameter can be treated. The minimum production lot is 500 kg (built-to-order product requiring prior consultation with customer). These coils can be used in progressive pressing and etching.
Field of use Dial plates of watches, decorative exteriors of AV, communications and IT equipment
Products or parts name Stainless steel for use as a building material, Piano Black
Products or parts description Providing sheen like urushi lacquer's that is impossible with plating or coating! A mirror-surfaced black stainless steel material
Features Stainless steel plates on which a less than one micrometer thickness oxidized membrane of neither plating nor coating is formed, effecting a colored appearance. These are a mirror-surfaced black stainless steel material that has urushi lacquer-like sheen and deep colored texture without losing the original metallic feels. Since no organic solvents are used at all in their production, these are an eco-product friendly to the global environment.
Field of use Exterior and interior decorations of shops
Products or parts name Electrolytic polishing of stainless steel
Products or parts description Burn traces on stainless steel welds are removed by polishing them electrochemically thus removing a layer of materials modified in welding
Features A treatment in which stainless steel is polished electrochemically Burn traces in welds are removed with shinning surface recovered. Since a layer of materials modified in welding is removed, the anti-corrosiveness of the surface is enhanced and a higher resistance to corrosion can be realized.
Field of use Semiconductor and liquid crystal equipment, heat exchanger, medical and food equipment
Products or parts name Chemical polishing of stainless steel
Products or parts description Components with a nested structure or shape made complex due to attachments, which are beyond the capability of electrolytic polishing, can be polished.
Features A treatment in which stainless steel is treated chemically Components with a nested structure or shape made complex due to attachments, which are beyond the capability of electrolytic polishing, can be polished.
Field of use Semiconductor and liquid crystal equipment
Products or parts name Electrolytic removal of stainless steel burrs
Products or parts description Minute burrs generated in etching and pressing are removed by electrolytic polishing.
Features Micrometer-size burrs cannot be removed by mechanical means. This is possible, however, with electrolytic polishing in which burrs are melted away.
Field of use Removal of minute burrs generated in etching and pressing
