Teflon capsule O-rings combine the advantages of both Teflon and rubber, possessing the chemical resistance of Teflon while also incorporating the elasticity of rubber. This allows for performance that leverages the benefits of both materials. Additionally, they can be produced at a lower cost compared to expensive perfluoroelastomers. The sizes correspond to standard sizes such as JIS, and the coating materials are available in two types: PFA and FEP, while the core rubber is available in two types: silicone and Viton.

We have achieved oxidation-free cutting up to SUS16T. With oxidation-free cutting (clean cut), there is no formation of oxide films or burn marks on the cutting surface. It is linked with the stocker system, allowing for automatic operation at night. We support large format processing up to 6,200 × 3,050. For example, for a φ3,000 ring, we can achieve precise laser cutting after welding the plates together. It is a simple and highly flexible laser cutting process! ● For more details, please download the catalog or contact us.

The brilliant cut has achieved unprecedented school rules and high-precision cutting. It is capable of cutting SUS10T, SS19T, and aluminum up to 10T, and can also drill and notch pipes up to φ200 in conjunction with the turntable. We accommodate various processing needs. The brilliant cut can also serve as an alternative to machining. By employing a cutting method that achieves a cutting surface roughness equivalent to ordinary machining finish (▽▽: Rz25μm or less), we have significantly improved the cutting surface roughness on thick plates. Additionally, optimal focal position settings have enhanced taper accuracy. For more details, please download the catalog or contact us.
