The new sounds are really good, but have few small suggestions/problems.
-First the sound of door opening for the robot port is to loud and I can hear it from very long distance even if I am in center of my factory with lot of noise. Suggestion to lower the sound somewhat and limit its range more closer to the robot port.
-The second one is the sound of robots, the bip bop bup. Its sound very annoying, but the bigger problem is that it is somewhat loud also and it makes them stand out more in all the sounds. I just want to sit in factory and listen to its noise, but this robots ruin it all

The second thing is changes to electronics. I liked the old one better, because they where easy to see what is what. The problem is that the electronic circuit and advance circuit are very similar in color now. I am not color blind but i have problems noticing what is what on my belts. Suggestion is make the advance circuit blue, but for processing unit make somewhat different new look. The older version look was really good because while processing unit had similar color to advance circuit, it had little different shape, so you can see easy what is on your belt.
Edit:
Two more things
The alien attack sound is also very loud and somewhat annoying
The color of plastic is almost same as steal. Maybe change it a little, more darker or something
