[Bulkar No. 6500 Processing Example] Large and Irregular Gaskets

[Bulkar No. 6500 Processing Example] Large and Irregular Gaskets

By combining water jet processing and adhesive processing, we can flexibly accommodate the production of large and complex-shaped products.

This is an example of producing a large and complex U-shaped gasket measuring 545mm x 709mm from a non-asbestos joint sheet "Valqua No. 6500" with a thickness of 3mm, based on the customer's drawing. The processing involved drilling 17 holes with a diameter of 21mm. Using our water jet cutting machine, we achieved high precision cutting directly from CAD data. Valqua No. 6500 is a non-asbestos general-purpose joint sheet made by combining organic and inorganic fibers with NBR and other materials. It demonstrates good sealing properties against general utility fluids and has a long track record in a wide range of applications, including petroleum refining, chemical plants, ships, and general piping. [Processing Features] - Proposal for cost reduction - Low cost and short delivery time without the need for a die - Direct processing from drawings - Easy repeat orders with data storage *For more details, please download the PDF or feel free to contact us.

Processing examples of synthetic cork gaskets (5K-25A FF)

High-precision support with water jet processing.

■Overview of Processing Example Product Name: Synthetic Cork Gasket Dimensions: 5K-25A FF (Thickness 6.0t) This example involves the production of a synthetic cork gasket for piping flanges conforming to the 5K-25A FF standard. It uses thick synthetic cork material with a thickness of 6.0t, requiring precision in the central hole and bolt hole positions based on flange standards. Water jet cutting is employed for processing, ensuring uniform cutting surfaces and high hole position accuracy even with thick materials. While maintaining the material's compressive resilience, it achieves stable sealing performance and ease of assembly. ■Product Features (Synthetic Cork) Synthetic cork is a sheet material made by uniformly mixing and compressing cork particles with synthetic rubber (such as NBR). It combines the compressive resilience of cork with the flexibility of rubber, demonstrating stable sealing properties. Its moderate elasticity makes it easy to maintain uniform surface pressure during bolt fastening, making it suitable for gaskets in automotive parts and machine covers, as well as oil pan gaskets. The oil-resistant type is common, but it is not suitable for high-temperature steam or strong solvent environments. It is widely used in applications requiring vibration absorption and sealing properties.

Due to the small diameter and specified inner diameter tolerance, water jet processing was adopted to achieve both shape reproducibility and dimensional accuracy. By adjusting the cutting conditions and cutting sequence, a finish that considers assembly compatibility has been realized.

TOMBO No.1995 Example of Processed Cut Gasket

TOMBO No.1995 Example of Processed Cut Gasket

Improving piping workability with water jet processing.

■Overview of Processing Example Product Name: Slit Gasket / Dimensions: Outer Diameter φ340 × Inner Diameter φ285 × Thickness 1.5mm, Bolt Holes φ12 × 12 Locations, PCD315 / This processing example involves the production of a slit gasket made from TOMBO No.1995 using water jet cutting. It is designed for retrofitting existing piping, allowing for installation without disassembling the piping by incorporating a slit in the gasket, which results in reduced construction time and improved maintenance. The 12 bolt holes are also processed with high precision. ■Product Features TOMBO No.1995 is a general-purpose joint sheet made from a blend of inorganic fibers and aramid fibers with oil-resistant rubber (NBR). It is suitable for fluids such as water, oil, and brine, and excels in a balance of processability, sealing performance, and flexibility. It is commonly used as gaskets for piping flanges and equipment in various industrial fields.

V6500 Joint Sheet Processing Example of R-Type Irregular Gasket

V6500 Joint Sheet Processing Example of R-Type Irregular Gasket

No. 6500 Joint Sheet R-Type Irregular Gasket Processing Example | Curved Shape Support by Water Jet Processing

Overview of Processing Example Product Name: R-shaped Irregular Gasket Dimensions: 479 × 753 (Reference) Material: No.6500 0.8t This case involves the production of a gasket with an irregular outer shape that includes an R shape and a multi-hole configuration, made from No.6500 joint sheet using water jet processing. For this project, which required precision in the outer shape including curved sections and accuracy in hole positioning, stable shape reproduction was achieved through data processing.

Case Study of Processing Steam Gaskets T1120

Case Study of Processing Steam Gaskets T1120

Case Study of Processing Steam Gaskets | Water Jet Processing for Center Holes and Multiple Holes

■Overview of Processing Example Product Name: T1120 Steam Gasket Dimensions: 128 square (Center hole φ76, multiple bolt holes) Material: TOMBO No.1120 Processing Method: Water Jet Cutting The outer shape is square, featuring a large diameter center hole in the middle and multiple mounting bolt holes arranged around it. Since this product is used in steam lines, dimensional accuracy to ensure stable sealing performance and positional accuracy of the center hole and bolt holes are critical requirements. This product uses T1120 material, which emphasizes steam resistance, aiming to maintain stable performance even under steam conditions. Water jet cutting was selected as the processing method. Since T1120 contains fibrous materials, it tends to exhibit variability in edge quality and dimensional accuracy when processed with cutting tools. By using the non-contact method of water jet cutting, it became possible to reproduce the shape, including the center hole and multiple holes, according to the drawings while minimizing the load on the material. As a result, this contributes to stabilizing processing accuracy and improving assembly compatibility.
