Equipment for protective mask ultrasonic reproduction

The copied device has the following fatal shortcomings.

One is that the quality of purchased raw materials cannot be guaranteed,

The core technology of the second production process has not been mastered.

Mask machine equipment often shows instability in medium and high power operations, and the product qualification rate is low. Sometimes the equipment is damaged. Such as transducer power transformers, the parameters of the magnetic materials used cannot be measured, magnetic saturation magnetic flux density (Bs), magnetic induction intensity (Bm), useful permeability (Ue), residual magnetic flux density (Br), coercive force (A / M), etc., the winding process is properly messy, and these home-based workshops cannot do it.
