Reliable technology that meets needs from general-purpose parts to super-large components!
We would like to introduce our "high-frequency hardening of rotating wheels," which can accommodate everything from single orders to mass production. Due to the short-time partial heating treatment characteristic of the high-frequency hardening method, which utilizes self-heating, the amount of distortion is minimized compared to conventional furnace-heated products, allowing for a reduction in labor and costs in subsequent processes. Based on our extensive experience, we design coils to quickly create hardening patterns that meet your specific needs. 【Features】 ■ Heating patterns suited to product shapes ■ Cost reduction due to low distortion ■ Capable of handling everything from single orders to mass production ■ Reliable quality ■ Quality assurance through automatic distortion removal machines *For more details, please refer to the PDF document or feel free to contact us.
