Our company concentrates on mold design and mold manufacture. The main products are Plastic Injection Molding, Injection Molded Parts and Custom Injection Mold. I can state from experience though that the US OEM's really didn't believe in their own cost models - sort of a "torpedos be damned" attitude. 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.

As a Chinese moldmaker,I have talked about this topic with one of my American partners, yes,he found the cost in China has raised those year, while he told me that the quality and effcient has improve as well .while, anyway, it's a problem for our cooperation, then we discuss how to low the cost ,so we discuss the molds, as Chinese standard and skillful technical to build the molds is really a big discount(eg, an USD8000 mold ,in Chinese standard would be USD4000-5000),because Chinese product is always share a good reputation ,yes,we focus on the product ,the shrinkage,the surface artistic and other factors ,then we make a nearly USD20,000 deal. Which it's helpful for Chinese and USA partners .Of course, it suits the small parts and the quantity should be make sure big enough, anyway, Chinese factory should living on the products.

You have to look at the part for starters. What is it, and what are the expectations on quality and use of the finished product. Obviously you would not want to use regrind product on a class a surface, or any type of show part that is not painted or plated in some form or fashion.

I think there are a few good points here. One thing to keep in mind is what is the GOAL. How much material could you save by having a hot runner to each part? Is it worth the expense of the hot runner? Will you actually save that much money by using a hot runner? Another thing to consider is hot runners will typically vary more during production. There are simply more things to go wrong with hot runners(more variables to account for). Cold runners are simple and will not change. Another thing to consider is the rheological factors. By using a hot runner you might find that higher shearing laminates will bias one portion of the part over another portion of the part and this could possibly differ from one cavity to the next. Of course this could all depend on the configuration. You can reduce a few of these variables by going to a hybrid system or a hot - to - cold. But once again I would say everything depends on what is the final GOAL. If there is not much to lose by creating some scrap/regrind.... I would say Hot - to - Cold or Full Cold runner. If you have a concern of cost of scrap/regrind and the part does not call for absolute precision then maybe a full hot system. Just be sure to concentrate once again on what is the GOAL.
