Processing examples of natural rubber white inspection port gaskets.
Supports curved shapes with water jet processing.
■Overview of Processing Example Product Name: Inspection Port Gasket Dimensions: 146.35W × 270L (Opening Angle 176°, Plate Thickness 5t, Mounting Holes φ8・φ10) This processing example is for a gasket designed for the inspection port of equipment. To ensure dimensional accuracy and shape reproducibility for the specifications that include curved contours and mounting holes, water jet processing has been adopted.
basic information
■Product Features (Natural Rubber) Natural rubber (NR) is a material derived from the sap of rubber trees, boasting excellent mechanical strength, elasticity, and abrasion resistance. While it is strong against tearing and bending, it is inferior in oil resistance and weather resistance. Therefore, it is widely used in environments that are not exposed to oil or direct sunlight, such as vibration-damping rubber, cushioning materials, and tires (blends). ■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 cut surface from press processing can also be improved with water jet cutting.
