Contract services for development, processing, joining, and heat treatment! We can handle prototypes and mass production starting from one piece.
Rare metal materials with characteristics such as heat resistance, corrosion resistance, high strength, and wear resistance. Our company develops and manufactures "functional components" aimed at further enhancing this rare metal-based material with features like low work function, long lifespan, and high-performance stabilization. [Examples of our product applications (one example)] - Analysis - Mass spectrometer (electron gun, electron source) - Semiconductor manufacturing equipment - (ion implantation) (exposure lamp) - Medical - CT scanner (X-ray source) (catheter) - Space - Ion engine, Hall thruster (heater) - Industrial - Magnetron (coil) - High-temperature furnace - (reflector) (structural components) [Material Development] Custom manufacturing of "functional materials" with special functions through years of sintering technology. [Precision Machining] Capable of fine processing of difficult-to-cut materials down to the micrometer level. We offer one-stop service from joining to assembly. [Coiling] Coiling of various sizes and materials from 1.5μm to thick materials is possible. [Thermal Treatment Contract] Our self-developed thermal treatment furnace can handle various atmospheres such as "vacuum, hydrogen, nitrogen, argon" at temperatures up to 2,700℃. [Coating] Functions are added according to purpose, such as insulation treatment and work function reduction. [Joining and Assembly] We propose solutions tailored to your needs, including welding, melting, and brazing.
