Plasma-resistant O-ring Fluoro Power DPR (special fluorine rubber)

Plasma-resistant O-ring Fluoro Power DPR (special fluorine rubber)

Special material (fluororubber + fluororesin) without the use of a compound material with O-ring cherry seal.

This is a special material that has excellent plasma resistance while maintaining a high cost advantage. Because it does not use any blending agents, it excels in low particle generation and demonstrates outstanding plasma resistance in dry processes for semiconductor and liquid crystal-related equipment. It is effective as a lower compatibility option for the non-filler type heat-resistant perfluoro material "FluoroPower FFN (FFKM-Plasma Resistant)." Sakura Seal Co., Ltd. offers a wide range of O-rings, from extremely small O-rings to large diameter rings, not only in standard sizes according to JIS standards but also in various sizes, supporting appropriate O-ring selection in terms of both material and size. * Various types of fluororubber, including perfluoro, are the materials that Sakura Seal Co., Ltd. specializes in the most. * We also accommodate shapes other than O-rings.

Heat-resistant O-ring "SGOINT(R)"

Heat-resistant O-ring "SGOINT(R)"

High intensity, high conductivity, high durability! Basic grade and steam-resistant grade are available in the lineup!

"SGOINT(R)" is a new concept heat-resistant O-ring that uses high-purity, shape-retaining single-layer carbon nanotubes manufactured by Zeon Corporation as a reinforcing filler in fluororubber (FKM) base material. The basic grade has excellent sealing properties at high temperatures and exhibits characteristics equivalent to those of higher heat-resistant products as long as the temperature is below 230°C. Additionally, there is a steam-resistant grade that offers stable steam resistance. 【Features】 ■ Suppression of "extrusion failure" in O-rings ■ Compatibility of high conductivity and low hardness ■ Maintenance of high temperature at 230°C while expanding the low-temperature range *For more details, please refer to the PDF document or feel free to contact us.

[Step-by-step explanation with images!] Reverse Engineering

Explaining the steps of reverse engineering with images! At GM, we create drawing data that can be modified using industrial CAD systems from measurement data.

We will create drawing data that can be modified in an industrial CAD system from measurement data using either "full reverse" or "simple reverse." - With full reverse, we will produce it for industrial applications. - With simple reverse, it will be output in the same shape as a polygon, making it cost-effective. For your company's challenges such as restoring items without data or drawings, and creating data from physical objects, please let GM Corporation assist you in reviewing the traditional manufacturing process. 【Procedure】 ■ Scan → ■ Point Cloud → ■ Curvature Analysis → ■ Manual Surface Creation → ■ CAD Data Production → ■ Shape Inspection Comparison For more details, please contact us or download the catalog.

Storage and reverse engineering of clay models and design shapes.

Storage and reverse engineering of clay models and design shapes.

Reverse engineering for industrial products!

We will create drawing data that can be modified using industrial CAD systems from measurement data. Please let GM Corporation assist you with your challenges, such as restoring items without data or drawings and creating data from physical objects, by reviewing the traditional manufacturing processes. [Challenge] We created prototypes like clay models, but when modifications are made, the original models are lost. We want to preserve the current shape. [Proposal] Save high-precision 3D data using 3D scanning. By performing reverse engineering, editing and modifications as 3D data become possible. For more details, please contact us or download the catalog.
