> This role reversal is an indicator of how the technology, trade, and know-how for injection molding has shifted to Shenzhen. Even if US has the manufacturing capacity, key parts of the knowledge ecosystem currently exist only in Shenzhen.
This is what really saddens me about outsourcing manufacturing from America, is that we lose the knowledge about manufacturing technology. Although we may be at the forefront of software development, in many areas of manufacturing technology the cutting edge development happens in China now.
I'd really like if we could bring about a revival in manufacturing engineering in the US. Other than the ecosystem effect, the main way that China has an advantage is labor cost, so I propose that we could build up a "Shenzhen of America" in the San Diego / Tijuana free trade zone. The repetitive work that takes a lot of hours would be done on the Mexico side, where labor is now almost as cheap as China. The manufacturing engineering and tool-making would both happen on the American side, bringing these jobs back to the USA from China.
San Diego / Tijuana are shipping ports on the Pacific, facilitating importing electronic components from China, Japan, and Korea, and then we could do all of the PCB fab, PCB assembly, injection molding, and final device assembly (as well as all tooling for all of these processes) over here in the Americas.
I'm very supportive of China's development but competition is good and as American citizens we can't just throw in the towel, we have to build our manufacturing knowledgebase back up and be willing to actually compete.
