Supports positioning accuracy with water jet processing.
■Overview of Processing Example Product Name: Washi Adhesive Gasket Dimensions: As specified in the drawing This processing example involves the production of a washi adhesive gasket used for sealing applications in equipment housings. The outer and inner periphery processing in a frame shape was specified, requiring positioning accuracy and stable reproducibility during assembly. To avoid thermal effects and material deformation, water jet processing was selected, achieving a balance between dimensional accuracy and assembly compatibility.

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 primarily excels in indoor hydraulic and pneumatic equipment. ■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. 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 cut surfaces from press processing can also be improved with water jet cutting.

Applications/Examples of results
■Q&A Q: Can dimensional accuracy be maintained with adhesive rubber? A: Due to non-contact processing, stable processing that minimizes the impact on the adhesive layer is possible. Q: Do you accommodate prototypes and small lots? A: Since no die is required, we can accommodate prototypes, small lots, and custom shapes. Q: Can I consult from the shape consideration stage? A: We respond from material selection and shape consideration based on usage conditions and installation environment. ■Processing of washi adhesive gaskets at Daiko At Daiko, we provide comprehensive support from material selection to processing method proposals and shape considerations, primarily for gaskets for industrial machinery. Utilizing water jet processing, we can flexibly accommodate prototypes, small lots, and custom shapes.
