Hello.
I just wanted to query the forum here for a few items that I am researching.
I manufacture polyurethane foam and I would like some information on any existing technology that will scan foam for dimensional purposes as well as any x-ray or similar technology for identifying internal defects.

Wasn’t sure where to put this as a discussion within the forum, but maybe someone can advise.

Thanks,

Welcome to the Cove, Avogel! :bigwave:

I'm not familiar with available technology that will measure what you're looking for. Hopefully, though, someone here in the Cove will be able to help.

Hello Avogel,

I am not an X-ray or scanning expert. But I did some research.
Maybe it's of use to you, maybe it's not. Disclaimer: I am not affiliated with this company.

I'll continue to look around.

Stijloor,
The size of my product varies around 5-6" thick. And our process runs about 54fpm. I am only at the beginning stages of researching this and not even sure if the technology is there yet. I would like this system to replace a 100% visual inspection requirement looking for internal defects as well as component placement.

Thank you for your findings thus far, It makes me want to beleive that it is possible.

Hello Avogel,

You may want to contact a manufacturer and find out if they are interested in developing a system for you. Can never hurt to ask. If it's commercially viable...who knows....

Here are some thoughts to consider
First classify you defective conditions with the thought of what is the change in density thru the cross section.
The change in density leads you to your x-ray type systems that are detecting changes in absorbtion of the radation as it goes thru the material. Higher density more xray absorbtion void or lower density and less xray absorbtion.
An differnat approach is to see how well the foam blocks a high intensity light source from being detected from the oppsite side. As long a you can detect that there is or is not a light source and if the "defects" allowed are large enough you might have an additional option. If you can see the "glow" of the light thru you material you might get some image recognition software to pick up these shawdows or brightness changes.

Either of the above can automate the process and tie to a marking sytem inline.
