Where in China to order the manufacture of high-quality plastic housing for an electronic device?

Question

Frame

There is a certain electronic device for which an elegant case is needed (we will make a 3D model ourselves). Estimated order quantity - from 1000 pieces. Sending inquiries to local firms that are engaged in plastic molding or molding in silicone molds did not yield results. Most simply ignored the request, or wrote a "just to get behind" response.
I had a similar experience with the production of boards, but in the end I found a good Chinese manufacturer with excellent quality. Now I want to find the same supplier of cases.
On Ali, he found manufacturers of standard cases for which the device could be adapted. Even ordered samples. As a result, I received a product not with the characteristics that were originally declared. Therefore, if someone had experience in successfully solving a similar problem, tell me please.

Answer 1

Sending inquiries to local firms

From time to time, requests for prices for goods come to our work, to which it is impossible to answer. The goods are not in stock, everything is made to order, there is no price list either. To calculate the price, you need a detailed technical specification or long-term communication with a specialist.
If answers like "send a drawing of the product to calculate the price" or "come to us, we'll discuss the details" you think "if only to lag behind" - then yes, only to China.
