Description of ceramic slit guides:
We have been producing numerous textile ceramic spare parts in production textile machinery over 15 years, including more than 1000 different types of ceramic wire guides, ceramic yarn guides, ceramic thread guides, also we support customized ceramic components with improved working surface and cost-optimized. These textile ceramic spare parts offer a series of advantages: excellent wear resistance, superb high hardness, great heat resistance, acid resistance, and low friction coefficient.
Whatever, it's prototyping with small lots or cost down needs for mass production, we could provide you an ideal solution.
Main features of ceramic slit guides:
1. Lowest possible yarn breakage rate with low yarn tensions
2. Highest yarn cleanliness without any fault silk occasion
3. Long service life on both special yarns and raw materials with aggressive additives
4. Exceptional wear resistance and hardness better than metal ones
5. Excellent mechanical strength, fracture toughness and bending strength
6. Good insulation, free of static electricity, resistant magnetic
7. Superb thermal conductivity coefficient and thermal shock property
8. Corrosion resistance in harsh working conditions
9. Excellent thermal shock resistance and good thermal stability
10. Nox-toxic, healthy material, eco-friendly material
11. Meet with RoHS, REACH regulation completely
Specification of ceramic slit guides:
1. Dimensions: max. size can be 100mm
2. Optional raw materials: zirconia(ZrO2),high purity alumina(Al2o3),titania(TiO2)
3. Another type of products: traverse guides, pigtails, eyelets, 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
