    Metal Technology Co. Ltd.’s Shiga plant recently obtained NADCAP certification, which is the certification system for special processing conducted by the international aerospace industry, for HIP (Hot Isostatic Pressing) processing.

    MTC has already obtained and maintained NADCAP certifications for Heat Treating, Inspection, and Pyrometry. HIP, however, is an additional process of Heat treating that mainly performed for defect removal in casting products. Metal Technology Co. Ltd. is the only company in Japan that holds NADCAP certification for HIP, and only one of three companies in Asia including our affiliate company Metal Technology (Suzhou) Co. Ltd.

    MTC continues to challenge areas where it is required to provide products that meet high quality standards. The Aerospace industry is one of the most important industries for MTC and we would like to enhance customer satisfaction through this acquisition of NADCAP certification.
    Due to the National Holiday ‘Golden Week’ our offices and factories will be officially closed during the following times - Monday April 29th 2019 to Monday May 6th 2019
    We will endeavor to answer your enquires and questions as soon as possible on our return on the 7th May 2019.
    We thank you in advance for your understanding.
    In cooperation with Metal technology Co. Ltd. (MTC) Shimoda Iron works Co. Ltd. has successfully obtained NORSOK certification.

    Metal Technology Co. Ltd. (MTC) is proud to announce an addition AM printer to our Technical Centre in Kanagawa. The new unit, which officially started operating on August 1st is a laser based unit made by 3D Systems. This unit has a work zone of around 1.4 times bigger compared to MTC’s existing laser additive manufacturing units. A maximum modeling area of 273mm × 273mm × 390mm when using a 30mm thick build plate. This will enable MTC to manufacture large products or produce multiple parts at the same time leading to cost reductions and enhanced savings for the environment as well as further flexibility in design too.

    Metal Technology Co. Ltd.’s designed and manufactured 8th Mercury Target Container unit, which was delivered to J-PARC (High Intensity Proton Accelerator Facility) in September 2017, has achieved high levels of operation. J–PARC, which is run by the Japan Atomic Energy Agency (JAEA), started the proton beam of around 300 kW after installing the Mercury Target Container (Unit 8) in early September 2017. After gradually raising the output, the unit successfully operated at 500 kW from on April 19, 2018 to June 30th, 2018. On July 3rd, 2018, we achieved our desired goal of operating continuously at 1 MW. This is a fantastic achievement that MTC is very proud to have achieved. We can confidently state that the Mercury Target Container (Unit 8) has displayed a high performance and our thanks go to all of those connected to the project.

    Metal Technology Co. Ltd. employee received the “Award for Excellence” at the 12th Nuclear Fusion Energy Alliance Workshop on June 29, 2018.
    Due to the recent developments in desirable energy for the future this was a wide-ranging academic workshop which aimed at mutual understanding in several related fields. Progress in research utilizing nuclear fusion energy, in fields such as core plasma and nuclear fusion engineering, are developing to support its use in future energy applications. Hironobu Kudo from our fusion group presented "Consideration of a blanket with box type ribs for production of a prototype reactor and concept for manufacturing", gaining high praise and the award at the workshop.

    -Presentation details-
    In the nuclear fusion prototype reactor, a blanket having the function of self-production of fuel, extraction of heat for power generation, and shielding is needed. The blanket requires high robustness (toughness) to allow high temperature/ high pressured cooling water to flow through under tough environmental conditions inside the reactor. Currently, a joint special team for designing a prototype reactor is developing a blanket installing ribs inside a box type casing to meet such demands. However, it has been an issue that this blanket structure was too complicated to manufacture by using general welding methods. Therefore, Hironobu proposed a method using diffusion bonding with Hot Isostatic Pressing (HIP) and proved that it can be manufactured with high accuracy of internal structure by making a partial mockup.

    The Mercury Target Container Unit 8 was delivered to J - PARC (High Intensity Proton Accelerator Facility) on the 22nd of September 2017. Metal Technology Co. Ltd.’s engineering division was responsible for designing and manufacturing the Mercury Target for the 7th time. Under the guidance of the Japan Atomic Energy Agency (JAEA), we thoroughly reviewed the contents of the design and production of Unit 7,the previous product, and applied several improvements to this new Unit. As a result, we were able to complete it after a 2 year design and production period. Currently it is being used for driving proton beam irradiation at J-PARC at about 300KW for most of the day at user operation status.

    ‘Monozukuri’ Subvention aides MTC in driving forward the next generation metallurgical material development.

    In cooperation with the High Energy Accelerator Research Organization (KEK), MTC is conducting powder processing in an ultra-highly pure atmosphere, aiming to produce parts for nuclear fusion or accelerators with high additional value. In order to accomplish this, MTC has created a new type of ultra-high purity glovebox that combines a vacuum chamber and an electric furnace. This project is driving forward the development of the processing of high purity metal powder.

    MTC plans to purchase a new facility that allows the processing of high purity metal powder in order to develop next generation metallurgical material. For that purpose MTC applied for the “Revised Financial Year 2017 Subvention for innovative development in manufacturing, commerce, and service” ①and was chosen by the Ibaraki Prefecture Small and Medium Enterprise Association②
