Nozzle can be divided into ruby nozzle and carbide nozzle, when the choose and buy should choose which kind of, want to consider the following several ways: the first thing is to see your quality request, winding coil by some coil quality request is higher, FBT industry should consider ruby nozzle, for example, if the electronic parameters of coil requirement is not so high, so choose the cheap and fine alloy wire mouth can completely meet the requirements.On the other hand is to look at the cost control requirements, if not very strict cost control that had better choose ruby nozzle;Vice can choose two kinds of alloy wire mouth nozzle performance compared with wear-resisting degree and the coefficient of friction so ruby nozzle greatly superior to alloy nozzle (the present experimental and theoretical data show that ruby nozzle wear life of the alloy nozzle is 10 times more)。
