Processing examples of natural rubber gaskets for light valves | Responding to complex shapes with water jet processing
■Overview of Processing Example Product Name: Natural Rubber Gasket for Light Valve Dimensions: As per drawing This processing example involves the fabrication of a natural rubber gasket used in light valves. The structure features bolt holes for mounting on the outer perimeter and an arc-shaped opening on the inside, requiring reliable sealing performance while following the opening and closing motion of the valve. The client's industry is related to industrial machinery dealing with valves and piping equipment. This product is a natural rubber gasket used for light valves, designed with an emphasis on compatibility and resilience at the valve seat. Water jet processing was employed for fabrication. Since natural rubber is prone to deformation during cutting, a non-contact processing method was chosen to achieve shape reproduction as per the drawing and stable processing accuracy. This helps minimize positional misalignment during assembly, leading to stable assembly characteristics and reproducibility.
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 that are typically achieved through 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.
