[Product description] [Micro reactor system] Our micro reactor systems can generate chemicals with high efficiency. Up to 20 kinds of reaction conditions can be programmed, so it is easy to optimize them. Systems can be customized as needed for multi-stage continuous reactions, photoreactions, and gas-liquid mixtures. [Micro mixers] We use a unique design to reduce low-pressure losses while achieving the highest level of mixing efficiency. We can also provide products made of acid-resistant Hastelloy materials.
[Company strength] We possess precision processing technologies for cemented carbide, diamond, and other very hard materials. Our technologies are reflected in tools, parts, and molds in various fields, such as machine tools, industrial machines, and the energy and chemical industries. We extend the life and functions of tools and parts to help customers improve production efficiency and quality, reduce running costs, and raise product power. We develop new products and make various proposals to meet customer needs by actively promoting R&D. [Business description] Our company provides tools, parts, devices, and consignment processing services to various industries with precision processing of cemented carbide, diamond, and other very hard materials as our core business. (Examples) Machine tools: abrasion-resistant diamond parts. Industrial machines: suction nozzles for mounters. Energy industry: slicing of electronic materials and diamond tools for slicing. Chemical industry: micro reactor systems for chemical synthesis. [Industry] Parts processing [Strength of products/technologies] The life and functions of tools and parts are extended by using cemented carbide, diamond, and other very hard materials for high-precision parts and tools. This is done to help customers improve production efficiency and quality, reduce running costs, and raise product power. We aim to reduce environmental burdens and improve production efficiency, so we are also promoting products such as diamond wire saws, micro reactor systems, and nozzle washers. [Representative's message] Our company has been meeting daring challenges to continue creating new Monozukuri craftsmanship required by the times ever since its foundation in 1954. As a result, we have acquired ultra-high-precision processing technologies for very hard materials that evolved from cemented carbide to diamond. Our motto is “Deep cultivation of diamond applied technologies.” We are continuing our innovative creation and aggressive challenges in new business fields, based on continuous R&D with full industry-academia-government collaboration. We are endeavoring to raise our presence in the world with our unique technical power as the market further globalizes. [Company structure for market development/overseas expansion] We have sales staff capable of attending to customers in English, Chinese, and Korean for inquiries from overseas companies. We established a local corporation in Shanghai, China in April 2013. Japanese and Chinese staff are stationed there to attend to customers at any time. We are also actively conducting transactions with major companies. We place and receive orders online and have established a fully satisfactory system for environmental friendliness and quality. Technical staff are available for consulting to solve technical issues.
