How can I get connected with quality Chinese manufacturers?

Question

I own a engineering company and need to find low cost metal, plastics parts makers.

Answer 1

Try Alibaba.com for direct connections.  If you need better services and extra helps such as quality control and English communications, you might want to use a sourcing agent.  Try to avoid individual agents, they might not be stable in the long run.  

You might also need the sourcing agent to take total responsibility for quality and delivery.
