Normally there's a button on that machine, each time you push it, one metal dome will be put on target position and then go to next position, without re-load or pick a metal dome individually.
Using metal dome in tube will accelerate the speed of metal dome assembly to save money and time. With a dome placement pen, or auto pick gun, dome in tube is convenient for assembly. Normally it's 1,000-1,500 pcs dome per hour, or can can be up to 2,000/hour, compared to human hand 300-500pcs/hour. To get a more fast speed, you need to use dome in Tape & Reel packing.
