Here are some of the problems (and my pet peeves) that can be found during a machine set-up. I have run into each of these many times over the years. Wrong part value: This can usually be traced to a purchasing, incoming inspection, or kitting mist

Hi, The answer is very complex depends on the type of machine, the operator's capabilities and process. There are machines that let you perform the above side then stick carts into the machine and produce. Event such a process is the length of a few

This number is going to vary hugely depending on the machine, how you operate and how many feeders you have. Smaller outfits might have a single operative whose job it is to setup, load, run & program the line. Regardless of how changeover focused t

That's what we do with our MSHII's...setup one carriage offline while the other one runs. We also have setup carts to load the feeders ahead of time and haul them out to the lines. Of course, when we exceed the carriage capacity of 75 slots for an

Unfortunately 95% of our runs require both sides of our Universal HSP's. We also have carts that hold one carriage worth of feeders on each side. Parts that carry over from one product to the next are flagged and relocated in the machine per the ne
