ナラサキ産業 List of Products and Services

This is an introduction to overseas carbon contract processing through our Chinese subsidiary (Shanghai). Our standard lineup includes Chinese-made fine carbon that is equivalent in grade to Japanese manufacturers. It is high-purity, dense carbon that has passed rigorous inspections compared to Japanese carbon. It demonstrates performance that is equal to or exceeds in terms of physical properties and purity. While maintaining high quality, we achieve low costs, and many Japanese companies are using our products. It is particularly optimal for cost reduction in medium to large lot parts and consumables related to carbon. Additionally, we have a wealth of manufacturing equipment with over 100 machining units and well-equipped inspection facilities, including 3D measuring instruments. As a cutting-edge carbon processing manufacturer, we receive many orders from around the world. We specialize in precision processing and have a track record in various fields such as semiconductors, solar cells, fuel cells, office automation equipment, electrodes, and other general industries. The materials we handle are not limited to Chinese products; we also stock Japanese and Western-made carbon, and we can propose various materials according to specifications. If you have any issues with carbon, please feel free to contact us.

This is an introduction to overseas fine ceramics through our Chinese subsidiary. In addition to oxide-based materials such as alumina and zirconia, we have recently expanded our offerings to include non-oxide ceramics such as silicon carbide and silicon nitride. In particular, our general-purpose alumina is available in a wide range of grades, from high-purity grades suitable for semiconductor applications with a purity of over 99.5% to general-purpose grades aimed at cost reduction with a purity of 96% or lower. We can propose purity and grade options tailored to your specifications. We also handle a variety of zirconia with a wealth of experience. Regarding manufacturing methods, we employ a low-pressure injection method that minimizes mold costs, and we excel at creating three-dimensional structures that can only be reproduced through molding, making it especially suitable for cost reduction in medium to large lots. We also offer post-sintering polishing, and mirror finishes are possible. Additionally, due to high demand, we produce a significant amount of non-oxide hard materials such as silicon carbide and silicon nitride. Depending on the application and needs, we can propose various purity and grade options, so please feel free to inquire.
