Processing examples of neoprene rubber (CR rubber) irregular parts | Shape adaptation through water jet processing
■Overview of Processing Example Product Name: Irregular Rubber Parts Dimensions: 1t × 70W × 600L Material: CR Rubber This case involves the production of irregular rubber parts with an asymmetrical shape that includes width variations and diagonal cuts, based on a long, strip-like form, using water jet processing. The structure is equipped with multiple through holes, intended for positioning and fixing applications within equipment and devices. Stable shape reproduction was achieved through data processing for shapes that cannot be accommodated by standard products, contributing to a reduction in adjustment work during assembly.

basic information
■Product Features (Material: Neoprene Rubber) Neoprene rubber (CR) is a rubber material that has a well-balanced combination of weather resistance, oil resistance, and heat resistance. It is particularly excellent in aging resistance and ozone resistance, making it strong for long-term outdoor use. It also possesses flame retardancy and mechanical strength, and is used in a wide range of applications such as construction gaskets, wire insulation, and industrial components. ■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 were significantly improved by traditional manual processing can achieve stable processing accuracy. The taper of the cut surface from press processing can also be improved with water jet cutting.
