Do you know if there is any decent plastic molding industry in Vietnam? I have something that needs off the shelf electronics (may buy them in China) but will have to meet manufacturers in person for the final assembly and plastic casing, which on a small series is probably going to be a sizeable portion of the cost (and seriously, that's more about ideology than cost anyway).
Even ordinary quality level plastics parts can often be easier to import from China there, moreover now. Even things like plastic bathtubs is a challenge at the moment. Not many options for small businesses there other than to work with garage factories, with all resulting complications.
I will be glad to get in touch with you if you really need to make it there, and you are really ready to pay. For a project under $100k you will likely pay a fee from 10% to 20%. Disclaimer, this is not a binding commercial offer
For plastic mold injection it's less about the infrastructure and more about how competent and reliable the supplier is. Circuit board assembly requires parts to be sourced. With plastics it's possible to be more logistically self-sufficient. You should be able to find what you need in Vietnam, but unfortunately I can't point to any specific sources.
