TOMBO No.1993 Gasket Processing Example
High-precision circular processing with water jet cutting!
■Overview of Processing Example Product Name: TOMBO No.1993 Gasket Dimensions: 3t φ220×φ166 This processing example involves the production of a circular gasket used in electric furnace-related equipment. It features a circular structure for both the inner and outer diameters, with evenly spaced bolt holes. It is designed for use in high-temperature environments, requiring stable sealing performance and assembly accuracy. To ensure dimensional accuracy and reproducibility, water jet cutting was employed, finishing the shape as per the design while minimizing thermal impact on the material.
basic information
■Product Features (TOMBO No.1993) TOMBO No.1993 is a joint sheet made from a special blend of rubber, aramid fibers, and inorganic fillers. It excels in heat resistance and steam resistance compared to TOMBO No.1995, making it suitable for high-temperature steam lines, hot water, and oil-based fluids. It is used for sealing pipes and equipment in more demanding conditions such as petroleum refining, chemical plants, and power stations. ■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. 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 of the cut surface from press processing can also be improved with water jet cutting.

■Q&A Q. Can you accommodate gasket processing for high-temperature applications? A. We utilize the characteristics of TOMBO No.1993 to support gasket processing designed for high-temperature conditions. Q. Can you ensure precision even for small diameter and multi-hole shapes? A. Through water jet processing, we can achieve high reproducibility for inner and outer diameters as well as bolt hole positions. Q. Is it possible to accommodate prototypes and small lots? A. Since we use a processing method that does not require molds, we can flexibly respond to prototypes, small lots, and custom shapes. ■Daiko's Capability At Daiko, we provide comprehensive support from material selection of joint sheets, including TOMBO No.1993, to processing method proposals and shape considerations. We can also accommodate prototypes, small lots, and custom projects.
