【Technical Data Presentation!】Compression Permanent Deformation of O-Rings

【Technical Data Presentation!】Compression Permanent Deformation of O-Rings

For customers in the Tokai area: Evaluated using the compression permanent strain rate (%) as a guideline for deformation (collapse) volume! We propose suitable products according to your application.

Our company estimates the lifespan of O-ring seals based on the compression set percentage. O-rings are used in a compressed state, and the sealing is achieved through the reaction force of the compressed O-ring. As the O-ring is used in a compressed state, it gradually experiences wear, leading to a decrease in reaction force. When the amount of wear becomes significant, the sealing function diminishes. The amount of wear (compression) can be evaluated as a percentage of the compression set. We can recommend suitable products based on your application. Please feel free to contact us when you need assistance. Attention customers in the Tokai region, especially in Shizuoka, Aichi, and Yamanashi prefectures! You can start with a consultation. Please do not hesitate to reach out. 【Test Overview】 ■ Samples (Fluoroelastomer O-rings): (1) NOK, (2) Company A, (3) Company B ■ Material: FKM hardness 70° ■ Wire diameter (thickness): φ2.4 ■ Test environmental conditions: 25% compression at 200℃ AIR ■ Measurement time intervals: After 24 hours, after 72 hours ■ Measurement items: Compression set percentage (%) = 2. Residual compression amount / 1. Compression amount at the time of testing x 100 *For more details, please refer to the PDF document or feel free to contact us.

We will perform machining on the poka-yoke ring made of POM (Delrin) colored material.

We will perform machining on the poka-yoke ring made of POM (Delrin) colored material.

We will machine the poka-yoke rings from POM (Delrin) colored material. Due to the characteristics of the material, we will strive to meet your requirements for tolerances and distortions as closely as possible.

We manufacture poka-yoke rings from POM (Delrin) colored materials. Available colors include red, yellow, blue, green, gray, black, and white. We can produce them in your preferred color. Poka-yoke devices used in equipment and jigs often have relatively simple shapes, allowing for quicker turnaround times in many cases. POM (Delrin, polyacetal) is a well-balanced material among engineering plastics and is also cost-effective, often compared to MC nylon. For mass production using NC lathe processing (Okuma), we calculate the number of pieces from bar stock, timing the supply of bar materials based on processing time and quantity to increase machine utilization. The factory operates on holidays, Saturdays, Sundays, and public holidays, and we can accommodate requests for necessary items right after the holidays. By responding quickly to issues such as unpreventable order omissions and jig damage, we aim to minimize risks and meet your requests as closely as possible. We have been in operation since our founding in 1971. I deeply feel that this is thanks to the support of our users. We look forward to your continued patronage.

Reverse engineering

Reverse engineering

Visualization of mold wear and the creation of high-precision replicas for the protection and exhibition of cultural properties.

"Reverse engineering" is a technology that involves 3D measuring (scanning) a physical object and creating a 3D model based on that measurement data. When a physical object exists but there is no 3D data or dimensional drawings, or when the entire product shape is overlaid with CAD data for comparison and verification, there are many ways to utilize this technology. It can be applied to various industries and sectors. 【Applicable Industries】 ■ Automotive (Vintage) ■ Aerospace ■ Space ■ Interior Design ■ Railways, etc. *For more details, please refer to the PDF materials or feel free to contact us.
