Excuse me, where can I find a factory for foreign processing? I do mechanical processing, and I have a CNC lathe processing center ... how to find a business?

My former boss was in sales, that is, he took orders for others to sell products in the factory, and then did a batch of work himself. Causing that big factory to become a small factory. He is very rich himself. There is also an opponent who has the same experience as him. You can talk to the bosses of other factories one by one. It's been like this from the beginning. It will be much better after we have established a long-term cooperative relationship in the future.
