Processing examples of NBR rubber uneven hole gaskets
Examples of processing uneven hole gaskets | Responding to multiple holes and irregular arrangements with water jet processing
■Overview of Processing Example Product Name: Uneven Hole Gasket Dimensions: t1 × Outer Diameter φ80 × Inner Diameter φ45 (P61 - Uneven Holes) Material: NBR Rubber Processing Method: Water Jet Cutting This processing example involves the production of an NBR rubber gasket with multiple holes arranged unevenly. It is used as a component part for industrial machinery, requiring dimensional accuracy to ensure reliable assembly even with non-uniform hole diameters and positions. By using water jet cutting, it achieves the reproduction of the hole arrangement and shape as per the design without the use of molds.
basic information
■Product Features (Material: NBR Rubber) NBR (Nitrile Rubber) has excellent oil resistance and is an ideal synthetic rubber for seals in fuel oils and lubricants. It also boasts superior mechanical strength and wear resistance, making it widely used in O-rings, gaskets, hoses, and more. However, its resistance to weather and ozone is low, making it unsuitable for outdoor use; it primarily excels in indoor hydraulic and pneumatic equipment. ■Processing Method (Water Jet Cutting) Water jet cutting is a water pressure cutting machine that uses high-pressure water to cut materials. It processes by spraying high-pressure water. The injection nozzle can be changed according to the processing material, allowing for the production of high-quality products in a short time. Additionally, the dimensional tolerances achieved through traditional manual processing are significantly improved, resulting in stable processing accuracy. The taper of the cutting surface from press processing can also be improved with water jet cutting.

■Q&A (Frequently Asked Questions) Q. Can you process gaskets with uneven hole arrangements? A. Yes, we can accommodate that. With water jet processing, we can manufacture uneven hole shapes with different hole diameters and arrangements according to the drawings without using molds. Q. Can I consult even if the drawings are not finalized? A. Yes, that is possible. After discussing the intended use and installation conditions, we will propose materials, shapes, and processing methods. Q. Can you handle prototypes or small lots? A. Yes, we can accommodate prototypes and small lots. By utilizing processing methods that do not require molds, we can flexibly produce even small quantity projects. Q. Is it possible to change to other rubber materials? A. Yes, we can discuss material changes according to the usage environment, such as EPDM or fluorine rubber. ■Daiko's Capability | For Processing Uneven Hole Gaskets, Choose Daiko At Daiko, we handle gaskets with uneven holes and special hole arrangements, from material selection to processing method consideration and shape proposals.
