For GM, their growing manufaturing and sales base in China trumped all short term costs. The real goal was to develop the local manufacturing base in China, then do car assembly, then engineering ... until an entire car can be engineered, sourced and built there. This makes sense longterm, but the short term plan was to import the parts back into the US for assembly here, and the near term costs were simply overwhelming.

Injection Mold Manufacturer is a leader among moldmakers. Our main focus is creating the highest quality products. Injection Mold Manufacturer is an america injection mold company located in Los angeles. Our company concentrates on mold design and mold manufacture. The main products are Plastic Injection Molding, Injection Molded Parts and Custom Injection Mold.

Our company quoted building a tool 2 weeks ago and our price was $32,000 when the China price came in they were only $4,000 less (this was specifying that they use the same quality components as us). By the time you add on shipping you jump another $2,000-$3,000. In addition to the shipping you have time delays in communication, proper communication, hoping they do everything correct, shipping time, etc, etc... The inherent costs are ridiculous. Companies do not consider this, they simply look at mold cost to mold cost. It doesn't make sense and I am glad that some are finally figuring that out.

As to the Chinese partners ,yes,most of the American firms have parter firms in China, while as you said ,the partner cost will be increased much especially,because both of them are growing at the same time ,so the American firms will turn to the new parters,that's why they will get so many introduction emails every day. Hope this comments would help all to understanding Chinese factories and try your best to be patience to commuction with them ,then you will found you get exceed your expection. If you are a seller, do you know what are the customer's mostly concern aspects on selecting an plastic injection mold maker in China? If you are a buyer, how do you select a reliable mold maker in China?

Part size, and cycle time are also crucial to determining material delivery methods. I have found using different materials for tooling components will also decrease cycle times by as much as 40%. There is alot to be said with the initial mold design pertaining to cost of components, the mold build and cycle time saved. Many customers wont spent the extra revenue on the proper manifold system, heat pipes, or even AmpCo inserts. To best determine what is best for the overall performance of the mold and production of parts, you should consult a full service tooling supplier.
