Supports high-precision hole processing with water jet machining.
■Overview of Processing Example Product Name: CR Rubber Soft Gasket (with Single-Sided Tape) Dimensions: 125W × 180L × φ111.1 Specifications: Thickness 3t / φ10 holes × 4 This product is a single-sided tape gasket made from CR rubber soft material. It has a rectangular shape with outer dimensions of 125mm × 180mm, featuring a central opening of φ111.1 and four φ10 holes. Soft rubber has a tendency to stretch and contract during processing, but by adopting water jet processing, we achieved high-precision machining without thermal impact, while maintaining the material properties. The single-sided tape specification improves workability and contributes to the efficiency of positioning tasks. This is a processing example that can stably handle mass production of 100 pieces per lot.

basic information
■Product Features (CR Rubber) Chloroprene rubber (CR rubber) is a synthetic rubber that excels in weather resistance, ozone resistance, and oil resistance. It has a good balance of mechanical strength and flexibility, and is excellent in vibration absorption and cushioning properties. It is widely used for outdoor applications and general industrial purposes, making it suitable for gaskets, packing, and vibration-damping materials. ■Processing Method (Water Jet Cutting) Water jet cutting is a hydraulic 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.

Applications/Examples of results
■Q&A Q1. Is dimensional accuracy stable even with soft rubber? A. By using water jet processing, which has no thermal effects, we can suppress expansion and distortion, achieving stable processing accuracy. Q2. Is it possible to process with adhesive tape on one side? A. By adjusting the processing conditions, we can accommodate specifications with adhesive tape. Q3. How accurate can the hole position be? A. By processing based on CAD data, we can consistently ensure uniform placement and positional accuracy. Q4. Can you handle both small lots and mass production? A. We flexibly accommodate everything from prototypes to mass production. ■Daiko's Capability We provide consistent support from material selection to processing method proposals, including soft materials, tape specifications, and special shapes. High precision and short delivery times are achieved through water jet processing. We have established a stable supply system for prototypes, small lots, and mass production.
