I know I'm very very late on this subject. But I had read it then and recently I was thinking about quality control in Chinese factories.
I would like to know the defect rate for factories making under contract "things" for foreigners (Apple electronic, BMW engines, you name it) and how this compare with European or US factories?
I own a Chinese brand Chinese made electronic multi meter since more than 15 years. Faultless and recently checked against a calibration standard. Spot on. IT replaced a Fluke (made in USA) that failed totally right after the warranty run out. (I complained to Fluke at that time and got a polite "go to hell" answer. So I bought the Chinese thing because it was so cheap the risk was minimal...
Having worked in the industry, I wonder how come you can make Allen keys,some of them good some of them bad on the same production line ? Idem for more complex parts. For example an engine made for BMW in a factory making quite the same engine for a Chinese brand having different building quality ?
I'm very puzzled.
So if anyone has an explanation, I will be glad to hear it !
