What Metal Technology does
Metal Technology Co. Ltd. (MTC / 金属技研株式会社) is a Tokyo-headquartered, private precision metal manufacturing services provider founded in 1960, operating 501–1,000 employees across facilities in Himeji, Ibaraki, Shiga, Toki, and Ebina (Japan), plus a wholly-owned Swedish subsidiary (MTC Powder Solutions AB). Its core technology portfolio spans Hot Isostatic Pressing (HIP), metal and resin additive manufacturing, heat treatment, vacuum brazing and diffusion bonding, superplastic forming, electron beam irradiation, and in-house non-destructive testing and 3D metrology. MTC operates more than 20 HIP units including the world's largest Giga-HIP (φ2050 x 4200 mm) and integrates these processes under one roof to deliver defect-free, near-net-shape, and complex-geometry metal parts.
The company's primary customers are government research institutions and large enterprises in nuclear fusion and accelerator science (ITER/QST, J-PARC/JAEA, KEK, RIKEN, Helical Fusion), aerospace and space (JAXA, ALE), semiconductors and LCD, oil & gas (Shimoda Iron Works), and medical/research applications. Revenue is generated through custom, project-based contract manufacturing with no public pricing and multi-year programs; sales run through a 6-step direct enterprise process (inquiry → technical meeting → quotation → ordering → processing+inspection → delivery) supplemented by trade-show presence, technical webinars, and Japanese/English digital content. Geographic reach is anchored in Japan with European coverage via the MTC-PS subsidiary (Hallstahammar, Sweden; new factory opened December 2024 with tripled capacity), and the company is pursuing further international expansion under a recently installed president. Quality and qualification moats — JIS Q 9100, ISO 14001, NORSOK M-650 (first in Japan for HIP-NNS duplex flanges, 2019), and an ITER Industry Wall plaque — underpin access to safety-critical programs in fusion, aerospace, and offshore energy.
