Processing example of D6000 3-pass gasket

Processing example of D6000 3-pass gasket

Case study of 3-pass gasket processing | Responding to complex shapes with water jet processing

■Overview of Processing Example Product Name: 3-Pass Gasket Dimensions: Outer Diameter φ990 × Inner Diameter φ960 × t3 This processing example involves the machining of a gasket with a 3-pass structure that divides the flow path. The client operates in the piping and equipment-related field. The product specifications require a configuration that includes a large-diameter ring shape along with internal partition shapes, necessitating reproducibility of the flow path shape and continuity of the seal line. The product feature is the ability to finish the outer shape, inner diameter, and internal shape as a single unit while accommodating the flow path division due to the 3-pass structure. The machining method selected was water jet cutting. This method allows for machining without thermal impact, making it easier to ensure shape reproducibility even for complex shapes, and enables machining of holes, inner diameters, and outer shapes according to the drawings. The effects of the machining include stable dimensional reproducibility of the internal shapes, ensuring assembly compatibility, and contributing to uniformity in finished quality.

D packing

D packing

Compared to punched rubber sheet gaskets, it has a more stable sealing performance at lower surface pressure!

The "D Packing" we handle is a gasket made by press-molding EPDM rubber into a specific cross-sectional shape. Its structure, featuring two O-ring shaped protrusions, demonstrates excellent sealing performance even at low tightening surface pressures. It can also be used with resin flanges and resin-lined flanges. Additionally, we offer the "D Packing PTFE Coated," which is made by press-heating and molding a PTFE film onto EPDM rubber molded products to create a bonded unit. 【Specifications】 ■ Maximum operating pressure: 0.98 MPa (approximately 10 kgf/cm³) ■ Operating temperature range: -40℃ to 100℃ ■ Available sizes: - 5K: 15A to 300A - 10K: 15A to 300A *For more details, please download the PDF or feel free to contact us.

Processing examples of NBR rubber C-shaped gaskets

Processing examples of NBR rubber C-shaped gaskets

Supports multiple hole processing with water jet cutting ■ Overview of processing examples

Dimensions: 81W × 96L (Plate thickness 3t) This case is an example of a manufactured plate gasket made of NBR rubber with C chamfering (C2) processing. It has a shape of 81W × 96L, with three φ10 holes and six φ5 holes arranged in the structure. Since hole position accuracy and processing reproducibility are important for multiple diameters of hole processing, water jet cutting was adopted. This method allows for processing without thermal impact, ensuring a uniform cutting surface while maintaining the material's elastic properties. Furthermore, the C chamfering processing helps to reduce interference during assembly, contributing to improved workability and stable sealing performance. ■ Product Features (NBR Rubber) NBR (Nitrile Rubber) has excellent oil resistance, making it an ideal synthetic rubber for seals in fuel oils and lubricants. It also has high mechanical strength and wear resistance, and is widely used in O-rings, gaskets, hoses, etc. However, its weather resistance and ozone resistance are low, making it unsuitable for outdoor use; it is mainly utilized in indoor hydraulic and pneumatic equipment.

[Water Jet Processing Example] Gasket with Handle

[Water Jet Processing Example] Gasket with Handle

We will introduce a case where having a handle made it easier to insert and position the gasket between the flanges!

We would like to introduce a processing case of "V6502 Black Super" conducted by Daiko Co., Ltd. Based on the customer's drawings, we manufactured a flange gasket for 10K-50A from a 3mm thick non-asbestos joint sheet "Vulcan No. V6502 (Black Super)." It was processed into a shape with handles using a water jet cutting machine. Having handles makes it easier to handle and manage the installation of the gasket. Additionally, since the handles protrude outside the flange, it helps prevent human error by forgetting to insert the gasket. [Case Overview] - Material: Vulcan No. V6502 (Black Super) - Product: Flange gasket for 10K-50A (with handles) - Work Details: Processed into a shape with handles using a water jet cutting machine *For more details, please download the PDF or feel free to contact us.

■Overview of Processing Example Product Name: TOMBO No.1995 Gasket Dimensions: 22×16×1t (Inner Diameter Tolerance 0 to +0.5) This processing example involves the production of a small-diameter ring-shaped gasket using TOMBO No.1995. 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.

Processing examples of partially cut gasket lower parts.

Processing examples of partially cut gasket lower parts.

Special shape support through water jet processing.

■Overview of Processing Example This case involves the processing of a gasket with a lower cut using the V6500 joint sheet. The outer circumference is primarily circular in shape, but it features a linear cut at the lower part of the gasket, which was specified to avoid interference with the equipment structure and surrounding components. The bolt holes are evenly spaced, requiring a balance between hole position accuracy and outer shape precision. In this case, water jet processing was adopted without using a die. By continuously processing the arc section and the lower cut section, we achieved the reproduction of the shape as per the design data and improved positioning accuracy during assembly.

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.
