Improvement of plasma resistance in semiconductor manufacturing processes, setters for molten metals, crucibles, rollers, etc., enhanced wettability for longer lifespan, and coating on graphite is also possible!
Various setters for firing such as MLCC and ferrite components, plasma-resistant materials for semiconductor manufacturing equipment, crucibles for various metal melting, transport rollers, and various quartz components. We have developed a dip coating technique for ceramics that was generally considered difficult, enabling thick film coatings on various fine ceramics, quartz, isotropic graphite, and refractory materials that are hydrophobic. Features: 1. Unique dipping technology provides: - High freedom of shape, strong adhesion to substrates, uniform film thickness, and high surface roughness. - While the design freedom for the coated object increases, consultation is required based on the shape. 2. Wide range of coating materials and target substrates: - Coatable ceramic materials: Most oxides and non-oxides (BN, SiC, Si3N4, etc.) - Target substrates: General fine ceramics, isotropic graphite, glass such as quartz, refractories, and metals (heat resistance temperature confirmation required). 3. High advantages of dipping over other coating methods: - Low cost (mass production effect) - Capable of handling three-dimensional structures, hollow shapes, and large sizes (size confirmation required). Film Thickness: Standard target film thickness: 50μ±5–10μ We optimize the use of composite ceramic films according to applications. Please feel free to contact us.
Inquire About This Product
basic information
We can respond after discussions based on a trial production of one piece. 1. Specify the product drawings and the type of ceramics to be coated. 2. For the product drawings, only the substrate is specified, and the ceramics to be coated will be discussed according to the desired performance. 3. Verify from scratch, including the substrate and coating types, based on the current theme. 4. Discuss coatings for complex shapes that are difficult with conventional methods. The unique dipping technology allows for high freedom of shape and adhesion, enabling discussions on various themes beyond thick films. In particular, with SDGs and carbon neutrality as paramount issues, improving the product lifecycle is an urgent theme. By effectively utilizing the dipping technology we are developing, we can greatly expect to extend the lifespan of components.

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.
