Processing examples of D6000 gaskets
【Processing Case Overview】 This is a processing case of a flange gasket using the non-asbestos joint sheet "D6000." Due to its ring shape with numerous bolt holes, the accuracy of hole positioning and mass production capability are crucial for this product. By adopting press processing, we ensure uniform hole pitch and high reproducibility, achieving stable quality for mass production. It is used as a sealing material for equipment applications where reliable fastening and airtightness are required. 【Product Features】 D6000 is a gasket material widely used as a non-asbestos joint sheet, known for its excellent balance of heat resistance, pressure resistance, and oil resistance. It demonstrates stable sealing performance in various piping flanges and equipment connections. Additionally, it has excellent compressive resilience, providing high follow-up during fastening and maintaining a stable sealing state even after bolt tightening. It also boasts excellent processability, compatible with various processing methods such as punching and water jet cutting, making it a versatile material that can accommodate a wide range of standard and custom shapes.

basic information
【Processing Method】 Press Processing Press processing is a method of machining that uses molds to punch materials, making it a highly efficient processing technique suitable for mass production. By creating a mold once, the same shape can be repeatedly produced with high precision in a short time, allowing for both cost reduction and quality stability. This method is particularly optimal for mass production projects, especially for products like flange gaskets that have many bolt holes, as it ensures uniformity in hole positioning and dimensional accuracy. 【Q&A】 Q1. Is it possible to process large-diameter flanges? A. We have a track record of producing large-diameter gaskets and can respond with optimal processing according to size. Q2. Can you handle products with many holes? A. We can ensure stable quality with uniform hole placement through press processing. Q3. Is mass production possible? A. Stable supply is possible through mass production processing using molds. Q4. Can you produce using other materials? A. We accommodate a wide range of materials, including rubber, resin, and various sheet materials.
