Supports large and multi-hole shapes with water jet processing.
Processing Case Overview Product Name: CR Rubber Frame-Shaped Gasket Dimensions: Outer dimension approximately 330 square / Inner diameter with opening / Multiple mounting holes This case is an example of processing a CR rubber frame-shaped gasket used for openings in equipment. The shape includes corners on both the outer and inner perimeters, with mounting holes arranged around it, requiring dimensional reproducibility and assembly compatibility. By adopting water jet processing, which allows for machining according to the drawings without using a die, stable quality manufacturing has been achieved. Product Features (CR 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 coatings, and industrial components.

basic information
Processing Method (Water Jet Cutting) A water jet is a hydraulic cutting machine that uses high-pressure water to cut materials. It processes by spraying high-pressure water. By changing the injection nozzle according to the processing material, high-quality products can be produced 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 cutting surface from press processing can also be improved with water jet cutting.

Q&A Q: What is the purpose of the frame shape and multi-hole specification? A: It is to ensure secure fixation to the equipment opening and to maintain uniform fastening force. Q: Is it possible to accommodate small lots or prototypes? A: Yes, we can flexibly accommodate this due to the use of water jet processing, which does not require molds. Q: Is it possible to consult about materials and shapes? A: Yes, we respond by considering the usage conditions and installation environment for material selection and shape design. CR Rubber Processing at Daiko At Daiko, we provide comprehensive support for CR rubber gaskets, from material selection and processing method proposals to the production of custom shapes. We utilize water jet processing, allowing us to flexibly accommodate prototypes and small lots.
