I've dealt with Chinese and American injection molding companies at work. I've had molds made in the US and the parts made locally. Finding an American injection molding company is easy. They are just very expensive by comparison. I've had a mold made in China and then sent to a US company to produce the parts here. No, the Chinese government does not own part of it. You do pay a premium to take possession of it though. I've also had molds made in China and the parts manufactured there. There are huge cost differences in each approach and which is the best choice is product specific. Each one has merit and US manufacturing is not always a viable option.
I will say that in regards to quality, that comes down to who you work with. I've had good products made in China and horrible ones made in the US at a higher cost. I've also experienced the reverse scenario.
A few years ago I got a mold quote for a project at work. A US company quoted us $40k for the tooling alone. It would take 6-8 weeks before they could begin the tooling and another 6-8 before we would have samples. The parts would then be made here as well.
I also quoted having the tooling made in China but sent here so the same molding place could make the parts. They wanted $25k and could have the tooling to the molding company in 6 weeks.
The last option was having the tooling made in China and the parts manufactured there. They wanted $2000 for the tooling but we didn't take possession of it. These were small volume prototypes so we went with this option. I had the actual molded parts in hand in less than 30 days from ordering the tooling and that time included shipping the parts from China.
Depending on the scenario, the only viable option to make a business model work is Chinese manufacturing. It's a risk of course but the price disparity may make that risk acceptable.
