Foxconn manufactures to Apple's specifications using equipment and materials paid for by Apple.
This is not how contract manufacturing usually works. In Apple's case, I really don't know.
Most of the time, a contract is agreed upon and the bill is paid according to the terms. In my manufacturing experience, I rarely pay before my items are in my hands. Chinese companies usually want the money up front but Apple has buying power, trust and history, so they probably do terms. Apple needs leverage over charge backs (defective units being returned), so having terms is in their best interest. Think light bleed, defective units (in general, scratches and just plain lack of QC, in some cases.
I'm sure they have a very good relationship though.
Apple doesn't own the equipment. Not sure where you got this idea from? Foxconn owns the equipment. Mainly, a bleep-ton of CNC machines and probably some casting and injection molding machines. You won't find this equipment on Apple's inventory list. I'm sure they help pay for it but they don't own it, not outright. I don't mind being corrected, if you have a citation.

huh? it's a public forum. not sure why anything you or i have said would need to be continued in private.. it's on topic.
Ok.
Do you have experience with mass-producing parts in Asia, specifically China? I do.
How can you compare custom wood-work with mass produced parts by automated machines and Chinese workers, earning about $2/day (I forget the actual rate)?

Do you mass-produce 10's of thousand of your wood products?
If Apple is given dimensions on, say the waterproof speaker, in the Apple Watch, they can adjust the case to accommodate the speaker or they can order enough, so that the manufacturer will augment the design, to fit in Apple's design envelope. This is one way. The most economical.
The other way, is for Apple to reinvent the wheel (that speaker) and make the design 100% custom... Which will cost a considerable amount more but will still use a product from a Chinese company.
I'm just wondering how you can compare your job to something of a scale of millions or units. Scale and location of manufacture drives the price way down. Communist manufacturing and labor, paired with millions of units, makes things ridiculous cheap.
