Durability is of chief importance to auto component manufacturers.
When engaged in high-volume production of taillights for consumer automobiles, manufacturers need to engineer the process to minimize the chance of accidentally damaging delicate inner components. This is especially true when building taillights, where the two leading welding methods produce less-than-ideal results from a quality control perspective.
Auto manufacturers have tried using many different welding processes over the decades – General Motors famously adopted ultrasonic welding in the 1970s, but gave up on the process when new technology made better, more consistent results possible.
Now, most automakers and component manufacturers rely on..
