Injection Molding Spec sheets
Injection Molding Spec sheets
(OP)
I build alot of injection molds in Asia, and one problem I run into is that the tool maker rushes to send me parts off of the tool (that I approved the tool design to) before some things are complete. I am sure this is for payment.
For example, the first samples from my last project the tool was ran without water lines being hooked up and a very long cycle. I have requested a video of these samples which has helped to some degree.
What I would like to know is, is there anyone that has made a tool approval spec sheet?
This would have things like cycle time and ejection methods, maybe steel temp after so long of a run, things of that nature.
I do travel to Asia freequently but I feel for the times I cant I need to make these tool shops accountable.

RE: Injection Molding Spec sheets
I'm afraid this is one of the drawbacks of having tools made a long way from where you are.
The real solution is to have your tools made locally. Or spend a lot of time attending tool trials in person.
What is the point of a tool trial sheet - anyone can put anything on it!
Is it really cheaper having tools made far away? Not in my experience after all the costs are added up.
I assume you are in the USA?

It depends on who you deal with wherever you are, but this is more critical with distance. Aus is closer to China than are most others here.
