1. Description
Our ceramic guide for textile machinery has many performance,high dielectric strength,excellent electrical resistance,abrasion resistance and high electrical insulation.And the ceramic guide for textile machinery has high accuracy can reach to Ra0.2.
The ceramic guide for textile machinery is used in knitting machine,winder guides for PA thread, twisting machinery, sensible fiber at low speed, weaving machinery, texturing machinery and spinning machinery.Please remember our ceramic guide.
In order to meet the needs of high quality and productivity of metal wire drawing machines production,our company has successfully developed the Al2O3 ceramic guide for textile machinery drawing capstans with the strong technical supports from the relative university and research institutes.
1. High strength and fracture toughness
2. High hardness and wear resistance
3. its coefficient of thermal expansion almost attain the common metal
4. Low thermal conductivity Featured with high strength and fracture toughness, ceramic guide for textile machineryhas been well known as the ceramics steel.
