jet plates, dog tails, air nozzles and so on
4. Tolerance: general tolerance ± 1% of the dimensions, or better
via a precision process
5. Surface finish: mirror surface, better than Ra0.1 at working
contact surface
Description of ceramic buncher bows:
Ceramic buncher bows are made of high aluminum oxides, or zirconium
oxide ceramics. Both technical ceramics have superb high hardness,
wear-resistance, and low friction coefficient because of their
special microstructure after high-temperature sintering.
In order to cater to different cost needs, the polishing grade is
to be classified to coarse polishing ( better than Ra0.8), fine
polishing (better than Ra0.4) and diamond polishing (Better than
Ra0.2). In the meantime, there are both sides diamond polishing and
single side diamond polishing.
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 improve production efficiency greatly.
