Injection molding tooling cost?
(OP)
How to reduce injection molding tooling cost? or how to negotiate the tooling cost with tool maker?
(Do you think if we do any kind of CAE or any other work related to injection molding tool will help us to reduce cost?)

RE: Injection molding tooling cost?
If you design the tooling you should save around 10-15% of the tool cost (at least in the UK).
I am sure a toolmaker would love you to do this as it then absolves him of any responsibility as to it's function (i.e. does it actually work??) Remember the old adage: "Beware of drawings as not only do they contain drawing errors, they contain all your design errors too!!"
Tooling sourced from low cost economies (e.g. China) is also cheaper but also fraught with difficulties regarding project control and many other factors (although I have bought tools from China and they have been excellent quality)

RE: Injection molding tooling cost?
Except to buy the tool from china/korea , how can we negotiate the tool price with toolmaker?
If CAE cost is so less than why some companies do Mold flow, shrinkage, warpage, cooling analysis inhoise instead of at tool maker?
RE: Injection molding tooling cost?
a) It justifies their job
b) They can make pretty diagrams of flow, warpage etc which probably are not too accurate anyway.

Tooling cost bears a direct relationship to part design too. Make the parts simple to make!!

If you like to use the toolmaker only as your workbench - May be
But !
"I am sure a toolmaker would love you to do this as it then absolves him of any responsibility as to it's function"
- make all moldflow and complete drawing of the mold / tool
- supply the steel to the toolmaker and care for the heat treatment
(if you by a lot of tools you can make an agreement with the steelmaker and get some extra bonus)
- supply all components to the toolmaker (limit switches, hydraulic cylinders, ejector pins, hot channel ...)
- make the sampling of the tool in your plant
- make the dimensional report in your plant
- make all final adjustments in your plant
- make all documentation (drawings, handbook) and spare parts by yourself
- take care about all accessories for handling
Please don't forgot: manage by yourself all changes from final customer
Your toolmaker "would love you" - he has to think only about machining and assembly
Sure, you don't have any problem to manage all this activities and you will get the tool in SHORTER times with BETTER quality and CHEAPER than from your toolmaker.
BUT SEROUSLY:
why everybody is asking for price reduction (at the end you get what you paid for) and
nobody is asking how to improve the mold.
A well done mold with good components from a good toolmaker will cost more, but this tool can make you save a lot of money during the lifetime of the tool (lower cycle time, less downtime for maintenance, less scrap - you will save a lot of money - but OK, it's very difficult to calculate and demonstrate this savings, it's easier to demonstrate the reduced tool price).
RE: Injection molding tooling cost?
For example, we did a mold for a washing machine tub. We recommended better gating and a slight wall stock reduction which meant quicker cycle. The mold ran a 60 second cycle 24/7. The first year they saved over $1million in material alone! I just wonder if a bargain basement design firm or mold-maker would have offered the same recommendations?

As for your question
(Do you think if we do any kind of CAE or any other work related to injection molding tool will help us to reduce cost?)
That will also have to do with the size of your purchasing orders. The bigger the PO more motivation for them to give you a better price for the tooling project.
