Plastic Injection Molding - China

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 molding 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.

A lot of good points have been brought up but there is a lot of key information missing to properly answer the question.

I'm personally a fan of hot runner molds, especially in multicavity tools in the right application.

There are a lot of things that need to be considered up front though.

The resin that the part is being molded from has to be considered, production quantity (assume it's high as you're considering 4 cavities), program life, color changes, staff familiarity with hot runner systems, etc.

And as Kevin stated we need to know what the goal is to give you some more solid advise.

Hot runner / drop systems have there pro's and con's hopefully with a little more info we could be of more help.

• Business Description: Many US producers have led customers thru the costing models, noting freight, quality, material variations, in transit losses, increased need for documentation and communications and increased management costs plus much more.
  
  Most guys will compete on an apples to apples basis, but quotes must be detailed for many to see the problems and the spreadsheets done for the purchaser to see the differentials.
  
  ACO Mold LLC is a leader among moldmakers.
  
  Our main focus is creating the highest quality products.
  
  ACO Mold LLC is a china inverter company located in Shenzhen.
  
  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.
  
  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.
