Product Description

The introduction of the ceramic wire pulley
 

Advanced ceramic melt spinning parts, including traverse guides, pigtail guides, air-jet nozzle, spin finish applicators have been extensively using the polymer fiber production. With our veteran knowledge of materials and growing experience for the design of the physical application in the production, we can design the contact surface with yarn, thread to be the ideal state with the diamond polishing finish.

We offer a number of ceramic yarn guides for thread guides, yarn forming, and yarn modification via different shaping methods in different technical raw materials as per customers' needs.

All these ceramic yarn guides are designed for use in processes at low yarn tensions with no damage. It helps decrease and maintain times and improves the production efficiency greatly.

Remark:

We have been producing a variety of ceramic yarn guides, including ceramic pigtails, ceramic traverse guides, ceramic bobbins, ceramic hooks, and so on.
