general question

(OP)
I have general question, if someone can help.

I'm from Customer side & we are the plastic part deisgn responsible. We awarded tool design, fabrication to one of the tooling company.

Now, what would be the customer role after awarding the businees to tooling company?

Definitely, different dept would have different role. Like checking tool dwgs,make sure guide pin locatios, parting line, tool schedule?

Can somneone give me proper details - what things need to consider during tool maturation?

RE: general question

From a military defense procurement perspective, your contract should contain, as a minimum, a preliminary design review (PDR) and a critical design review (CDR).

A PDR is where the supplier shows that his preliminary design meets all the requirements.

A CDR is where the supplier has completed his design drawings and is ready to procure/fabricate the design.

You can refer to MIL-STD-1521, which is available here: http://assist.daps.dla.mil/quicksearch
although the site is currently down.

or here:

MIL-STD-1521 is, of course, gross overkill, but it'll give you some ideas.

However, you are limited by what your contract specifies, so you need to review your contract first.

I apologize but My question refering to automotive underhood component

RE: general question

Three people, or groups of people, are involved in design and production of plastic parts.

The customer must talk to the molder.

The molder must talk to the moldmaker.

I have mostly worked for smaller outfits, where the process is perhaps a bit simpified, but in my experience, it should not ordinarily be necessary for the customer to talk to the moldmaker, or to see a mold drawing or the mold itself.

I have on occasion been forced to buy the tooling separately and then persuade a molder to use it, but that process has always turned out to be much more expensive, in money and in time, than just working with the molder, paying him for the tooling, and allowing him to make or buy the tooling and to deal with the moldmakers.

RE: general question

par1,

It doesn't fundamentally change the design/build process.  A designer starts with requirements that he allocates and partitions to his design.  He comes up with a preliminary design, runs tests, does simulations, etc.  He finalizes the design, builds it, and tests it for compliance.
