basic information
■Product Features (NBR Rubber) NBR (Nitrile Rubber) is a synthetic rubber with excellent oil resistance, making it ideal for seals in fuel oils and lubricants. It also boasts superior mechanical strength and abrasion resistance, and is widely used in O-rings, gaskets, hoses, and more. However, its weather resistance and ozone resistance are low, making it unsuitable for outdoor use; it is primarily utilized in indoor hydraulic and pneumatic equipment.

Applications/Examples of results
■Processing Method (Water Jet Cutting) Water jet cutting is a hydraulic cutting machine that uses high-pressure water to cut materials. It processes by spraying high-pressure water. By changing the injection nozzle according to the processing material, high-quality products can be produced in a short time. Additionally, the dimensional tolerances that were significantly affected by traditional manual processing are greatly improved, resulting in stable processing accuracy. The taper on the cutting surface from press processing can also be improved with water jet cutting. ■Q&A (Frequently Asked Questions) Q. Can you handle outer R shapes and tape application simultaneously? A. Yes. We can provide a consistent service from water jet cutting to tape application. Q. Can I consult even if I don't have a drawing? A. We can accommodate handwritten sketches and dimension confirmation from actual items. Q. Can I request small lots? A. We are flexible in accommodating requests from a single prototype to mass production. ■Daiko's Capability At Daiko, we consider the characteristics of various rubber materials, including NBR rubber, and can handle complex specifications such as frame shapes, outer R shapes, and tape application. We also welcome inquiries for prototypes, small lots, and custom dimensions. For gasket processing that takes assembly and workability into account, please consult Daiko.
