Please, don't go this route. It will be not the machine that you expect. If it is Chinese good machine, you should be able to find distributor close by, if it is a clone of a well known machine, they will have problems selling it to you. Man Corp and

For me it looks like a scheduling issue. You can do time studies on your assemblies and predict the best workload, based on scheduling the jobs in the right sequence. Also it sounds like you have only one operator. Train more people to operate will h
