We have over 15 years of experience in the production of ceramic yarn guides for the textile and wire industries and can help you find the right solution for your guiding issues.
Advanced ceramic yarn guides including ceramic pigtail guides, ceramic roller guides, ceramic eyelet guides, ceramic traverse guides, ceramic hook guides, etc., have been widely used in high-speed spinning machines. With our extensive material knowledge and growing production experience, we can design the contact surface with the yarn/thread to ideally have a mirror polished surface.
We offer a number of ceramic yarn guides via different shaping methods in different technical raw materials as per customers' needs.
The main features of textile ceramic parts
Our ceramic yarn guides are designed for use in processes at low yarn tensions with no damage. It helps decrease and maintain times and improve production efficiency greatly.
