Hot plate plastic welding is one of the machines that caught my attention. I read and learned that this machine is used to weld sizable and crooked shaped plastic parts with difficult curves and joint lines. It must be cool to work on this thing. The kind of welding I do at work is steal welding; once in a while I weld some broken brackets and parts for the busses and since I don’t do it often I basically lose my touch and steady coordination, which can be hard at times. Anyway, it’s nice to learn something new each day. At least in the future when I encounter such machine I will have an idea of what it is for. I don’t think my work will buy a machine like this though.
