Top Seiko is a company that handles various brittle materials products such as ceramics and glass, as well as high melting point metal products like tungsten and molybdenum. For customers who value speed in launching new products, our company supports the development and mass production startup by providing a wide variety of tool inventory, numerous processing machines, and rapid processing based on the experience of skilled technicians. Additionally, depending on the processing requirements, we conduct test processing when necessary. We repeat test processing multiple times until satisfactory results are achieved, determining the best processing conditions. 【Features】 ■ Support for mass production and development startup ■ Implementation of test processing ■ Material selection ■ Selection of optimal processing machines ■ Attachment of measurement data *For more details, please refer to the PDF materials or feel free to contact us.

We perform grinding, cutting, and polishing of various ceramics, quartz glass, and difficult-to-machine materials such as tungsten and molybdenum. With the motto "If it can be processed in iron, there is nothing that cannot be processed in other materials," we have accumulated technology over the years. We primarily use machining centers, owning over 70 three-axis machines and more than 15 five-axis machines, as well as ultra-high precision machines with linear specifications. Additionally, we have a comprehensive range of measuring equipment, including three-dimensional measuring machines, image measuring instruments, and laser microscopes. We have established a quality assurance system, and we can perform cleaning and drying in a clean room, as well as vacuum packaging. Even if there is little experience with ceramics or high melting point metals, we consider factors such as heat resistance, low expansion, high hardness, wear resistance, and electrical insulation to select and propose materials that meet your requirements. If you have new materials or are struggling with processing materials, please feel free to consult with us. 【Business Activities】 ○ Processing and sales of various ceramics and brittle materials such as quartz glass ○ Processing and sales of high melting point metals such as tungsten and molybdenum ● For more details, please download our catalog or feel free to contact us.

We are currently offering the "Material Processing Guide & Success Case Collection," which is helpful for material selection in research and development as well as product manufacturing! This guide condenses data on major materials, from high melting point metals like tungsten and molybdenum to common metals like stainless steel, ceramics, metal composites, and glass. It compares items such as heat resistance temperature and thermal conductivity in graphs, making the differences in physical properties immediately clear. We are also providing case studies on productivity improvements through material changes as a set! [Contents of the Material Processing Guide] ○ High melting point metals ○ Common metals ○ Semi-metals ○ Ceramics ○ Glass and more We provide introductions and the latest information on precision cutting products made from hard and brittle materials like ceramics and glass, as well as high melting point metals like tungsten and molybdenum. *We updated our "Company Profile" in December 2022. Please download the "Material Processing Guide" and "Successful Material Change Cases" from the link below!
