Training for processing of battery holder with wire

We had a training class for processing of battery holder with wire tonight.

First step, we need to do the processing for the wire, we have the cutting machines with twist and tin function together, the machine is automatic, we just put one roll of wire on the machine and set the length, then put the button, we can get the wire with tinned ends. 

Second step, we need to do the processing for mounting the wires (red and black) and springs on the plastic Battery holder, in order to make sure our wires and springs are mounted on the plastic holders steady, we have two workers to mount the red wire and black wire separately. 

At last, we need to test the battery holder circuit to make sure the products are qualified.
