Hi I am interested in manufacturing small aftermarket automotive parts, nothing specific but for example, seat brackets and lambo door kits. I am trying to decide between a laser or a tool based cnc. I am new to this subject and have a lot more research to do. I was wondering if laser cnc machines can make molds or do they just cut/engrave? For example lets say I have a 2" thick and 5" x 5" w+l piece of metal and want to make a circle in it that is 1" thick and 3" around, can this be done with a laser or do I need to do it with a CNC machine. Also do the laser cutters do laser welding or is that a whole other machine?
