4:15 You just created counter draft on the outer surface, making it impossible to open the mold with the split line being in the obvious upper corners. In order to have the outer surface drafted as shown you would need slider movement to the sides. Sorry, I have been working with injection molding over 15 years. :)
what if the model you need to make have internal draft angle but outside can't be simply ejected with drafting and require multi piece mold to be made? in this case let's say 6 part mold where front and back, would be interchangable as well as left and right, but a model already have natural parting line for top and sides build in how to inject plastic into such a mold toy train bodies , architectural models , things with a lot of windows and thinn surface details that stick out and would hold 2 piece mold
Wouldn't this affect the product's final output? If it has a GD&T symbol of straightness and flatness etc... the product needs to be perfectly straight or flat. By adding draft angle wouldn't it affect this property?
Thanks for the video, it's useful to learn about the reasons why draft angles are necessary! Would you guys be able to make one on the tolerances needed when 3D printing and injection moulding two parts that fit together?
i dont mean to be so off topic but does someone know of a way to log back into an Instagram account..? I stupidly forgot my password. I would love any tips you can offer me.
@Otto Leonel i really appreciate your reply. I got to the site thru google and I'm trying it out atm. I see it takes a while so I will get back to you later with my results.
I keep hearing different degrees of angle from different people. One company told me a 1 degree draft angle would suffice, but here your inner draft angles were 1.5 degrees. Is there a set standard?
Love the use of the 3DP examples, very clear!

But angle is different between top and bottom of draft area then how to maintain uniform wall thickness of the part?
Thank you! Very clear :), enjoyed learning about this thanks to u!
Great video guys! At 3:59 did you apply a negative draft angle on purpose or it was supposed to be positive?
Hi João! Thanks for the compliment. The draft angle you are talking about is positive. We did not ad a negative draft angle. Hope that helps!
Thank u very much sir it's very helpful for me
What program did you use to create the diagrams with black background?
great video thanks, when the series will continue?
Why are opposite Side Draft Angles here? On other videos, Part like your. Draft angles ( outside and inside are in same direction

Hi Kamaal, great to hear you appreciate the video. That is definitely a very interesting topic and we will add it to our ideas!

@Otto Leonel It worked and I now got access to my account again. I'm so happy!
Thanks so much, you saved my ass !
Gracias!
Please do some videos about slider and lifter.

Hi Richard, thanks for your question. In short: no. It depends on the design of your part and the surface finish.
very good vedio，can you do it more,thanks
Hi bro can you make a video on positive & negative draft angle
I think if you change video topic to something like what is draft analysis, you would be able to draw in more people into this video.
Thanks for the tip Yorem! We might try that.
