BUSINESS Business

We provide a large number of high-performance, high-quality key components such as piston rings, camshafts, valve seat inserts, cylinder liners, and other parts for internal combustion engines, as well as casting parts for car bodies and seal rings for transmissions, for which we have earned a solid reputation both in Japan and abroad.
We will continue to develop our proprietary technologies and actively contribute to the development of next-generation automobiles, including internal combustion engines using hydrogen and synthetic fuels and parts for electric vehicles.

Piston rings used in the main engines for propulsion of ultla-large container vessels with 400 meter length have a diameter of approximately 1 meter.
The seal rings for generator facilities and industrial equipments are also some of our main products, some of which are as large as 1.5 meters in diameter.
These products are manufactured applying the latest technology in terms of materials, surface treatment and machining, etc. to support the foundation of our societal infrastructure.

Piping products play a major role in industrial fields such as lifelines, disaster prevention systems, and plants that support a comfortable and safe urban life.
We provide piping products that our customers are happy with through technological innovation under a variety of brands including the highly reliable "Koma Zirushi," which has been certified and accredited by JIS, JWWA, JPF, the Fire Equipment and Safety Center of Japan, and the Japan Stainless Steel Association.

When using metal materials to manufacture products with fine and complex shapes, precision machining is difficult and costly. Metal injection molding technology is the solution to such problems. Metal powders are molded and sintered to produce products that meet specifications and requirements in order to create a resource and energy-saving production environment. We work to support people's daily lives in various fields not only for automotive components such as steering parts but also robotics, communications and office automation equipment, precision medical equipment, and leisure goods.

In the Thermal Engineering field, we design, develop and manufacture our own heating elements and performs heating equipment integration for various industrial furnaces. We have a lineup of products designed for various needs, such as "PYROMAX™," a metallic heating element with excellent durability and "PYROMAX SUPER™," a superior and advanced ceramic heating element with a maximum operating temperature at 1800°C. Our thermal control technology and product quality has been tested and evaluated over many years and is highly evaluated in a wide range of industrial applications.

EMC (Electro-Magnetic Compatibility) refers to both EMI (Electro-Magnetic Interference), in which radio waves emitted by electronic devices do not interfere with other devices, and EMS (Electro-Magnetic Susceptibility), in which they are not affected by interference from other devices.
We develop and sell "anechoic chambers" and other products for measuring electromagnetic waves as part of our EMC-related business.

NiFreeT™, a proprietary titanium tantalum alloy, has strength similar to that of human bones and high biocompatibility, making it suitable for use in bio-implantable devices. We are currently working with leading manufacturers and research institutions in Japan and abroad to jointly develop products.
Normeca Asia, a trading company specializing in emergency medical products for use during disasters, provides comprehensive solutions for all types of disasters, including infectious diseases and natural disasters, to support the BCP of medical institutions and companies.

In addition to the products manufactured by us, we handle a variety of products in our function as a trading company. Demand for RVs has been increasing amid a recent boom in outdoor activities, and there are many who wish to lead a lifestyle more in line with all the outdoors has to offer. In collaboration with leading international brands, we offer a diverse lineup of products, including exterior parts for RVs and infrastructure products such as generators, toilets, and air conditioners. In addition, we are also meeting the needs of parts related to semiconductor manufacturing and industrial equipment products that provide support for various industries.
