This is the procedure to assembling the machine. Our production line is not a flow-line production. Because we think it is boring for the workers. So we put some procedure together to let 1 worker to finished to avoid that the worker only do 1 moves for a whole days. And we are using the piece-work system not a time-work system. And it give workers more motivation to do it good and more. that is why our month capability can be 13,000 pcs per month based on about 120 workers. And cost of labor is lower then makes our price is more competitive.
