Process FMEA (PFMEA) For Plastic Injection Molding - Seeking Example

[KidPaddy]

Hi guys!
Anyone out there who has samples of FMEA PLAN regarding Plastic Injection.......tnx .....more power to all!

 

[Marc]

You are wanting a Process FMEA example, correct?

 

[KidPaddy]

Yes sir that is correct, but specifically that is patterned after plastic injection.......thank you very much.

There are some samples here:
Generic Molding FMEA - Can some one provide me with an example?

FMEA - plastic molding - Not sure how to start

much aprreciation for the directions sir_knight

Measuring when parts are warm

I have just started working in plastics. I am looking for suggstions in education myself in this porcess. Such as correlation on measurements done when the part come out of the mold vs an hour or day later. Also, color standards.
Can anyone point me to a few good books or web sites or share their experiences in controlling and measuring molded parts?

Thank you visual boards standard

Wow, plastics is really something. I am wondering if anyone can share their best practices in regard to visual boards. They have boards with defects and boards for color They're all over the place but it is doubtfull to me that the
boards are makign an impact on training or improving rejects. Then there is storing them all and controllign them.

Any ideas?

This is a tough call without knowing more about the culture. It could be that while there's no apparent usefulness, they serve as a sort of security blanket. It's usually not a good idea to evaluate color at the machine; different lighting sources can have a profound affect on color perception. There's a phenomenon called metamerism that will cause wildly different results when viewing samples under different light sources. It's best to use a controlled light source and objective measurement and make sure that your evaluation method jibes with your customers'. You can see some examples here.

As for the sample boards, if you can look at reject data before and after the boards were in place you might be able to form an objective opinion as to their utility. Another option would be to selectively remove some boards and see if there's any adverse effect. You might also want to talk to operators and get their feelings; there might be usefulness that you're not seeing.
