Alumina Ceramic Eyelet Wire Guide for Winding and Textile
Textile ceramic eyelet apply to the coiling machine and spinning and weaving machinery, is in common use fault silk another piece, is used to demand no high fault silk occasion. Silk thread slides when the job, in China eye outside, for reducing friction, must raise material hardness, smoothness and form. Our company selects and uses 99%'s Al2O3, hardness greater than HRa88, density 3.85, surpasses essence throwing Ra0.2.
The textile ceramic eyelets is used to set less (friction is also less) location of pressure right. For cost reduction, according to using a request, smoothness polishing handicraft is allotted being (0.8 throw Ra) roughly, is throw (Ra accurate 0.4), surpasses essence throwing (Ra0.2).
Ceramic eyelets Be that single face is super-accurate at the same time mark throw and two-sided super-accurate throw. Specification of China eye many, select and use specification listing in common use in sopport a customer the day afer tomorrow now, also may demand making to order according to the customer.
