it's so refreshing to see it in the industrial sense. I've really only seen them in academic labs. Very helpful video to get out of the academic bubble.
Love the video, thanks for all the information you guys put out. I really do enjoy watching and reading everything you create even Jasons how to clean a mold (LOL)
there could have been some alternate factors pointed out in the video, but for a new molding professional I think they could have a generally better understanding of the two morphologies. Decent job Marty
I was going to point out that the spelling of amorphous was incorrect at the beginning, then I noticed it was corrected later on in the video :). Before talking about the post mould shrinkage of plastic, it may have been helpful to explain that as the plastic is heated up, the volume increases. Also some discussion and explanation that amorphous and semi crystalline plastics have a glass transition temperature and what that means. Thanks for sharing this presentation, I am currently in the process of giving theory training to apprentices in our company. I have been explaining why some plastics are transparent and some are opaque. I will be showing them your video sometime soon.
Hi, thank you for video. I have a question. If during the injection we do more cooling, semi-crystalline are could increase o no? Cooling can effect more creating semi-crystalline area?
Cooling has an impact on the amount of crystallinity. The faster the cooling ( colder) the less crystal development. Hotter molds allow more time for the crystals to grow. It is important to run the mold at the correct temperature recommended by the material supplier.
Can you make a video on how to determine process windows for semi crystalline , crystalline and amorphous plastics material for injection molding Thanks for making videos Love and respect from India
All materials are either semi crystalline or amorphous. Process windows will be highly dependent on tool design and material selection. A video would be near impossible as your specific results will need to be catered to your situation.
I was never so clear about Amorphous and Crystalline materials and their behaviour. Thanks for this video. Really helpful.
We're so happy it was helpful! Thanks for watching!

I can understand about the explaination on this video. This is simple but a lot of information. Thank you
We're so happy it was helpful! Thank you for watching!!
Hey I know this guy. Marty assisted with the MM1 I took a few years ago. Good to see he's still around.
Awesome!! He sure is, and we're lucky to have him! :)
Excellent lecture.
We're so happy you enjoyed it, thanks for watching!

We agree that this doesn't cover EVERYTHING, but we just wanted to give a basic overview. Thanks for watching!
excellent explanation, thank you
We're so glad you enjoyed it! Thanks for watching!

Thanks so much for watching and for the feedback! We hope this is helpful for your apprentices. 🙂

That's a great idea!! We'll add it to the list! Thanks! 🙂
Sorry Marty, shouldn't the PP sample be 6.2715 long?
Good catch! 🤣
Hi sir, background noise disturb a lot.
Thank you for the feedback!! 🙂
