Processing of high-hardness parts such as roll presses used in coaters (coating machines) is possible! We excel in difficult machining processes such as interrupted cutting due to our expertise.
Seiwa Co., Ltd. specializes in processing single items and small lots, accommodating various materials. We are particularly skilled in lathe processing of die steel (SKD11, SKD60) after hardening, as well as lathe processing of SUS630. With a large number of machine tools, including NC lathes, we can respond to short delivery times. Additionally, we collaborate with reliable partner companies to handle heat treatment, allowing us to provide integrated production and delivery when you request our services. We manufacture press rolls used in roll presses for coaters, and thanks to our years of knowledge and technology, we can deliver them at low cost. Press rolls require lathe processing of SKD11, which can be challenging. If you are considering a new roll press system, please reach out to our experienced team. *For more details, please refer to the PDF or contact us.*

basic information
**Friction Shaft** We also manufacture 3-inch and 6-inch friction shafts. A friction shaft is a replacement for a winding shaft that achieves "high productivity" and brings about the effects of high quality and high profitability. It will transform your current "winding machine" into a facility for profit expansion. Please consider Seiwa's "KS Air Friction Shaft." We also accommodate the manufacturing of shafts with link widths tailored to other inch sizes and products, so please feel free to contact us. **Delivery Destinations** - Battery manufacturers - Chemical manufacturers - Plastic manufacturers - Automotive manufacturers - Pharmaceutical manufacturers - Paper manufacturers - Slitter manufacturers
