Ultrasonic welders are used for all sorts of stuff from plastic packaging to face masks and so on. They can basically weld many materials together with intense vibration.
Asking because I royally hate sewing machines, and most of my projects could go pretty fast and efficient if I used a sonic welder. I think. ;)
I don’t find many people using these for MYOG, but since folks around here are often more savvy with tech, someone might have experience. If you have used one, what’s your experience? Do they weld permanently enough or do the welds come loose without extra care or steps? Stuff like that.
They run from around $400 and up, with $600 being the cheapest one you can get that has timing controls. Cheaper than $600 only allows a set timer and has to be done multiple times for extra welding.
