Of course, the application scope of the rapid widening at the same time, the problems caused by too many for example, dispensing needle drawing and tailing, as the common problem of dispensing needles in production for a long time, seriously affect the dispensing quality and production efficiency. So there is no way to avoid what is happening or reduce this problem?
Of course, here by the system dispensing technicians to a simple exposition to solve the dispensing needle drawing and tailing solution.
