We would like to introduce a processing case where a large product measuring 310mm × 1466mm was created from a special material made by bonding a PTFE sheet to an EPDM rubber block with a thickness of 55mm. This product is a high-performance composite that combines the elasticity and weather resistance of EPDM rubber with the chemical resistance and slip properties of PTFE. The part in contact with liquids is made of PTFE, which is strong against chemicals, while the main body is made of EPDM, providing a solid elastic sealing function. Using our water jet cutting machine, we achieved high-precision cutting of bonded materials with different hardness levels without delaminating the adhesive surfaces.

■Overview of Processing Example Product Name: Natural Rubber Gasket for Light Valve Dimensions: As per drawing This processing example involves the fabrication of a natural rubber gasket used in light valves. The structure features bolt holes for mounting on the outer perimeter and an arc-shaped opening on the inside, requiring reliable sealing performance while following the opening and closing motion of the valve. The client's industry is related to industrial machinery dealing with valves and piping equipment. This product is a natural rubber gasket used for light valves, designed with an emphasis on compatibility and resilience at the valve seat. Water jet processing was employed for fabrication. Since natural rubber is prone to deformation during cutting, a non-contact processing method was chosen to achieve shape reproduction as per the drawing and stable processing accuracy. This helps minimize positional misalignment during assembly, leading to stable assembly characteristics and reproducibility.

In plant and building construction, the insulation of equipment with "curved surfaces," such as piping, air ducts, and tanks, has always been a challenge for contractors. If flat board insulation materials are forcibly bent during installation, cracks and gaps (heat bridges) can occur, significantly reducing insulation performance. On the other hand, blanket rolls can sometimes make it difficult to maintain the shape during installation. To meet these seemingly contradictory demands of "perfect conformity to curved surfaces" and "ease of installation," Nichias Corporation has developed a high-performance rock wool insulation material called "MG Belt" using its unique technology. *For more details on the column, please refer to the related links.

In insulation and soundproofing work for plants and factory equipment, the material's "thermal insulation performance" and "sound absorption performance," along with "ease of installation" and "shape retention (durability) after installation," become extremely important. In particular, for complex shapes and vertical surfaces, such as the walls of boilers exposed to high temperatures and the heads of large tanks, the fixation and retention of insulation materials have been long-standing challenges. To meet the conflicting demands of "high-performance insulation" and "reliable workability and durability," Nichias Corporation has developed the "MG Rass Board," which is a high-performance rock wool insulation material reinforced with metal. *For detailed content of the column, please refer to the related links.

In plant, factory, and building construction, the greatest enemy of insulation materials is "water." Fiber-based insulation materials such as rock wool and glass wool experience a rapid increase in thermal conductivity once their air layers are replaced by water, resulting in a near-total loss of their insulating function. To address this fundamental issue in outdoor and humid environments, Nichias Corporation has developed the "MG Hassui Board." This high-performance product retains the excellent basic performance of Nichias's renowned rock wool insulation material, "MG Board," while adding powerful "water-repellent performance." In this article, based on Nichias Corporation's official product catalog, we will thoroughly explain why the MG Hassui Board is chosen as an insulation and sound absorption solution for outdoor equipment and humid environments, from the core of its performance to the critical temperature limit of "150°C" that you must absolutely know when selecting it. *For detailed content of the column, please refer to the related links.

"Rubber gaskets and packing" support the performance and safety of equipment. However, even when grouped under "rubber," there are many types, each possessing completely different characteristics (such as oil resistance, weather resistance, heat resistance, etc.). If this selection is incorrect, it can lead to serious issues such as "rubber swelling due to oil" or "cracking due to ozone." In this article, we will compare and explain the characteristics of nine major types of rubber materials, providing the foundation for a "selection guide" to help you choose the right product for your application. *For more detailed information, please refer to the related links.

In the industrial sector, there are extreme high-temperature and high-pressure areas that cannot be reached with composites made of rubber, resin, or non-metals, such as plants, offshore facilities, and pressure vessels. To contain fluids with absolute reliability under such harsh conditions, the "metal gasket," composed entirely of metal, was designed, with the "ring joint gasket" being a representative example. In this article, based on the official product documentation from Vulcan, we will thoroughly explain why ring joint gaskets exhibit high sealing performance, the secrets of their structure, the differences between the two important shapes, "octagonal" and "oval," and the correct material selection and usage to fully utilize their capabilities. *For detailed content of the column, please refer to the related links.

Leakage from gaskets in plant and factory piping flanges is a serious issue that directly leads to production stoppages, energy losses, and significant safety accidents. Many of these troubles are caused by "inadequate management of tightening force," that is, poor construction. In this article, we will explain why "torque management" is essential for gasket sealing, the fundamental theory behind it, and an overview of the three common types of tightening failures (insufficient, excessive, and uneven tightening) along with their examples and countermeasures. *For detailed content of the column, please refer to the related links.
