A representative of high-performance machinable ceramics with excellent machinability in all aspects!
"Hotobear" is a machinable ceramic with excellent electrical insulation and thermal insulation properties. It has versatility and outstanding performance, making it suitable for a wide range of processing from simple shapes to complex shapes, fine and high-precision machining. Its machinability also provides delivery advantages, making it effective for small-scale prototypes starting from one piece to urgent projects. In the case of fine ceramics, which are difficult to machine, there are many situations where they are over-specified, and our product is well-suited as an alternative in such cases. Due to its heat resistance and extremely low thermal conductivity, it is also used as an insulating material in high-temperature environments where conventional insulation materials cannot be applied. Moreover, the processing precision that cannot be achieved with conventional insulation materials is made possible with ceramics, allowing our product to be utilized as a high-precision insulating material. [Features] - Fast processing speed due to machinability, providing delivery advantages - Low cost - Low thermal conductivity with insulating properties - Excellent electrical insulation - Superior thermal insulation [Application Examples] - Insulating materials for semiconductor manufacturing equipment - Insulating components - Vacuum device components - Heat treatment jigs *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Overview】 This is a machinable ceramic, a cutting-friendly material, with a glassy matrix and uniformly precipitated fluorine mica and zirconia microcrystals. Since it is a material that can only be processed from sheets, there are shapes that cannot be reproduced. There are also limitations on the maximum manufacturing size, but production of long and large parts is possible depending on the content. We also offer special grades, such as those with added silicon nitride or in black for optical inspection equipment. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Narasaki Sangyo Co., Ltd. "Functional Materials Division" specializes in high-performance material contract processing. The materials we handle fall into "five categories": 1. Ceramics/Glass 2. Metals 3. Engineering Plastics 4. Carbon 5. Surface Treatment We offer a wide range of services, and if you provide us with a single production drawing, we can deliver various materials and surface treatments as a one-stop solution. We cater to everything from general-purpose to specialty materials, including high-precision, fine, electrical discharge, laser processing, as well as surface treatments such as coating, precision cleaning, and blasting. Our particular strength lies in high-precision and short-lead-time processing of ceramics. By machining from pre-fired materials, we achieve short lead times for ceramics that traditionally take several months. We handle a wide range of ceramics, including machinable ceramics like Hotovel, as well as fine ceramics such as alumina and zirconia, and non-oxide ceramics like silicon carbide, silicon nitride, and aluminum nitride. We are also actively engaged in proposing cost reductions for overseas ceramics and other international materials. We can accommodate various contract processing projects, from prototype development starting with a quantity of one to mass production.
