An explosion ripped through a large manufacturing facility owned by key Apple supplier Hon Hai, better known as Foxconn, killing two and injuring 16, Chinese state media reported.

The cause of the blast was still under investigation on Saturday morning local time and Apple had no immediate comment.

Local media said that production had been halted at the facility, which was said to be used for making the iPad 2 tablet.

If the shutdown is lengthy, it could have an impact on Apple’s ability to keep up with demand for the second-generation gadget. Apple’s delivery times have improved in recent weeks after a rocky launch period.

Depending on the cause, the accident could also bring more attention to working conditions at Hon Hai, which has been faulted for a rash of suicides and other problems.

So far, though, none of the finger-pointing at Apple’s suppliers has done anything to damage the company’s brand appeal.
