Experience With Connecting Factories with Each Other

[u/Aorus_]

I have a supplier who makes carbon fiber tubes and can connect them with cnc'd parts. I tell him what kind of hybrid carbon fiber / cnc'd part I need and he is able to make it. His factory only does carbon fiber work and they subcontract the cnc work out. This supplier, quite frankly, shits the bed quite often. Misses critical details. Has bad english. The whole 9 yards. I keep him around because of the ability to give him projects that involve cnc'ing and carbon fiber, as I use both often. I had a thought. Would it be reasonable to find a factory that does just cnc work and a factory that does just carbon fiber work and introduce them to each other? Would it be likely that they would, through each factory's engineers talking with each other, be able to make a mechanically sound product? Can anyone speak about their experience connecting chinese factories with each other for the purpose of combining their specialties?

We make all sorts of sub-assemblies that require multiple inputs, some of which come from in-house capabilities and some of which are outsourced. Often companies will provide suggestions for suppliers they have had good luck with and we will reach out and vet them, and then add them to our supplier list. The customer only buys the product they want and we manage the supply chain. I avoid the situation where the customer manages our supply chain as much as possible, because while I can normally dual source a material or component, it gets weird if I have to send a non-conformance or other form of non-compliance warning to a customer.
