C-shaped cross-section low tightening pressure metal seal C-ring 'C-FLEX TM'

C-shaped cross-section low tightening pressure metal seal C-ring 'C-FLEX TM'

We introduce C-rings with sections and thicknesses that take into account compressive loads.

The sealing concept of "C-FLEX TM" is the elastic deformation of a metal seal with a C-shaped cross-section. It is compensated by the internal pressure of the equipment to accommodate low design tightening pressure and uneven surfaces of the flange. It is utilized in a wide range of applications, including crude oil extraction, industrial turbines, valves, aerospace, automotive, and SOFC fuel cells (750°C for 40,000 hours). 【Features】 ■ Unique C-shaped cross-section structure ■ Cross-sectional diameter and thickness designed for low tightening pressure ■ Compatible with internal pressure, external pressure, and axial direction ■ Low design tightening pressure ■ Pressure range: from medium vacuum to 200 MPa (2000 bar) ■ Temperature range: -273 to 730°C (-46 to 1350°F) ■ The structure enhances sealing performance by providing auxiliary force from the operating pressure on the equipment side to the C-FLEX. *For more details, please refer to the PDF document or feel free to contact us.

Nickel low design tightening pressure (low Y) Texseal spring-loaded C-ring

Nickel low design tightening pressure (low Y) Texseal spring-loaded C-ring

By applying TEXEAL® (patented texture processing) to the conventional HelicoFlex, we enhance the sealing performance.

"HELICOFLEX TEXEAL" is an innovative technology born from years of sealing expertise, contributing to a reduction in maintenance burdens due to its low design tightening pressure. It can accommodate a wide range of dimensions, and by incorporating it at the design stage, it reduces the overall cost of the equipment. It decreases lifecycle costs and improves sealing performance without increasing tightening torque. [Features] - Reduces overall equipment costs by incorporating it at the design stage - Compatible with nickel instead of silver in nuclear applications - MTBF (Mean Time Between Failures) - Reduction in LCC (Lifecycle Cost) - Optimizes sealing performance without increasing tightening torque *For more details, please refer to the related link page or feel free to contact us.

[Technical data presentation in progress!] Ozone crack

[Technical data presentation in progress!] Ozone crack

For customers in the Tokai area: It's important to choose materials suitable for the usage environment! Please consult us if you are having trouble with rubber materials.

At our company, we select materials based on our extensive knowledge and proven track record in sales and verification. Some rubber materials can develop cracks on their surface when exposed to ozone or ultraviolet light. This occurs because, when left in the atmosphere, ozone causes a chemical reaction in the rubber, leading to molecular-level breakage. It is important to choose materials suitable for the usage environment of the rubber. If you are struggling with rubber material selection, please feel free to consult us. A must-see for customers in the Tokai region, especially in Shizuoka, Aichi, and Yamanashi prefectures! You can start with a consultation. Please do not hesitate to contact us. 【Testing Conditions (Excerpt)】 ■Test specimen: O-ring P-24 (Inner diameter 13.8 x wire diameter 3.5) ■Rubber materials: Nitrile (NBR), Fluoroelastomer (FKM), Silicone (VMQ), Ethylene Propylene (EPDM) ■Elongation rates: 10%, 20%, 30% ■Testing location: Outdoor exposure ■Evaluation criteria: Degree of cracking *For more details, please refer to the PDF document or feel free to contact us.

【Processing results available】 Thread cutting chamfering

【Processing results available】 Thread cutting chamfering

Introducing the benefits of the screw cutting process! We have experience in screw cutting and chamfering processing.

Our company has experience in thread cutting chamfering processing. In thread cutting, it is necessary to create a relief groove at the end of the thread, but establishing a relief groove can reduce strength and increase the risk of breakage. Therefore, we would like to introduce the benefits of a processing method that chamfers the end of the thread, eliminating the need for a relief groove. 【Processing Benefits】 "By chamfering, it is no longer necessary to create a neck that is narrower than the inner diameter of the thread at the incomplete thread section at the end of the thread, which increases the strength of the thread and reduces negative impacts on seals." Masakatsu Yamagishi, (1986) Introduction to NC Machine Tools (Illustrated) p.100. Tokyo Denki University Publishing. *For more details, please feel free to contact us.

Attention engineers who are struggling without drawings or CAD designs despite having the product!

Reverse engineering of mold parts is possible! *Flyer with examples available.

Reverse engineering refers to the process of restoring an existing product. It is carried out when there is a product but no drawings or CAD files available. When you have a product but lack drawings or CAD files, please make use of reverse engineering. 【Procedure】 ■ Meetings are extremely important. This is because the cost can vary significantly depending on how detailed the intended use is, how rough the design can be, and what tolerances need to be included. *For more details, please contact us or download the PDF to view.

[Example] Reverse engineering based on 3D scan data.

I will introduce two methods of reverse engineering based on 3D scan data.

There are various methods for reverse engineering, and the choice of method affects the output data. Therefore, it is necessary to select the optimal method according to the purpose of data use and required accuracy. We will introduce two methods of reverse engineering based on 3D scan data, along with their procedures and characteristics. <Reverse Engineering Based on Cross-Sectional Contour Shape> [Step 1] Acquisition of shape data (point cloud data) using a laser scanner. [Step 2] Polygonization and mesh correction. [Step 3] Modeling is performed using 3D modeling software and 3D CAD software. A sketch of the cross-section is created on a reference plane, and solid shapes are generated using functions such as extrusion and rotation. <Reverse Engineering Based on Surface Shape> [Step 1] Acquisition of shape data (point cloud data) using a laser scanner. [Step 2] Polygonization and mesh correction. [Step 3] Modeling is performed using 3D modeling software and 3D CAD software. A surface that fits the mesh to the surface shape is created for all surfaces to generate a solid shape.
