In a previous article we discussed the difference between the Eclipse process of individually drawing (pressing) the bowls of double bowl sinks and then welding then together.

This process while cheaper produces a lighter and therefore noisier sink.
Here is a short video of a portion recent presentation we did on sinks and faucets where we discussed the topic.
