The description of ceramic wire guides
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.Datasheet of Technical ceramics
