Processing examples of natural rubber inspection port gaskets
Supports various shapes with water jet cutting.
■Overview of Processing Example Product Name: Inspection Port Gasket / Dimensions: 146.37W × 270L × 5t, Hole Diameter φ9 × 4 Locations (with R) / This processing example is an inspection port gasket made from white natural rubber (hardness 40). It is used as a sealing material between the inspection port cover and the frame of the equipment. It has a complex shape with an irregular outer contour and four bolt holes, but it was cut with high precision without the need for a mold using water jet processing. There was no thermal impact on the rubber material, and it was finished without compromising the flexible properties of natural rubber. ■Product Features Natural rubber (NR) is made from the sap of rubber trees and boasts 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).
basic information
■Processing Method 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 were significantly affected by traditional manual processing are greatly improved, resulting in stable processing accuracy. The taper on the cut surface from press processing can also be improved with water jet processing. ■Q&A Q: Can I choose the hardness of natural rubber? A: Yes, we can accommodate various hardness levels starting from hardness 40. We will suggest the optimal hardness based on your application. Q: Can you provide natural rubber in colors other than white? A: We also handle black and various colored rubbers. We will provide a quote based on your requests. Q: Can dimensional accuracy be maintained even with irregular shapes? A: With water jet processing, high-precision processing of approximately ±0.1mm is possible, even for complex shapes.
