At Niimi Sangyo Co., Ltd., we offer contract processing of "high-precision clearance parts made of ceramics," such as air bearing and valveless piston pumps (piston/cylinder). Since it is an air bearing, there is no wear during operation due to non-contact, but there is a risk of wear when not in operation. With Niimi Sangyo's ceramic "air bearings," the wear resistance is superior compared to metals, which reduces the risk of wear. Additionally, one of the features is the ability to create grooves at the micron level. 【Main Features】 ■ Surface characteristics suitable for the intended use ■ Excellent wear resistance ■ Excellent heat resistance ■ Excellent chemical resistance *Please check the PDF for various ceramic parts available for download.

Our company specializes in the manufacturing of a wide variety of small ceramic components, including "ceramic parts for medical devices" that are highly resistant to corrosion, high quality, and low cost due to our unique manufacturing methods. We also produce "micro ceramic screws" such as M1 and M2, which are essential components in medical devices, as well as medical pump shafts and "thin-walled pipes." In our catalog, we showcase various products along with their materials and features, while also introducing "points for reducing the cost of ceramic parts." We can bring to life the ideas from manufacturers like "it would be great if we could make something like this." Please feel free to consult with us! 【Examples of Ceramic Parts Applications】 ■ Plunger for piston pumps ■ Piston and cylinder for valve-less piston pumps ■ Electrostatic nozzle that solved electrostatic issues in high-pressure spraying ■ Carbon dioxide laser tip ■ Slim nozzle tip with a tapered inner diameter for medical devices *If you have an idea for something that may not be possible to create, please contact us, and we will respond smoothly.

Our company specializes in the manufacturing of "ceramic pump components" that achieve high quality at low prices through our unique production methods. We have been responding to the production of various small ceramic parts, including rotating sliding components, for many years and have a wealth of experience in the medical industry.

We offer "ceramic plungers and ceramic pistons/cylinders for valve-less pumps" that achieve high quality through precise manufacturing technology for metering pumps. Plunger-type metering pumps are a type of pump that delivers fluid in accurate amounts, and our ceramic plungers are used in metering pumps for applications such as biochemical automatic analyzers and artificial dialysis machines. Additionally, valve-less piston metering pumps are used in applications requiring precise fluid control, and our ceramic pistons and cylinders achieve precise fluid control by strictly managing the clearance between the piston and cylinder to below 5μm. They are adopted in valve-less piston metering pumps used in artificial dialysis machines and biochemical automatic analyzers. *For more details, please download the PDF or feel free to contact us.

Our company offers ceramic plungers and cylinder ceramic valves for metering pumps, utilizing advanced precision machining technology. By employing alumina-zirconia ceramics, we achieve excellent wear resistance, chemical resistance, and smooth sliding properties. With high dimensional accuracy and reliability that support precise fluid control, these components are used in metering pumps for medical devices such as specimen testing equipment and artificial dialysis machines. Furthermore, our integrated production system, from raw materials to precision machining and inspection, ensures high quality and stable supply. *For more details, please download the PDF or feel free to contact us.*
