Because Yan Gao-frequency Bian Xiao answers for you: Master Gao-frequency voltage, many enterprises and factory owners are recruiting. Because they are familiar with the operation of Gao-frequency machines, they can do proofing of various PVC/EVA products. It is even more difficult to recruit teachers who can do, repair and modify voltage molds. I suggest that you recruit some positions through the recruitment network to raise the salary of high-frequency voltage masters, which will attract some high-level technicians to apply. Our company has recruited high-frequency technicians before.
