You've taken a very difficult topic and presented it in a way that makes total sense. This is an excellent tutorial.

[alexanderbuschpilot]

That helped me 100%. I had been looking for this for a long time. Many thanks for that. 😎👍

[IamSpartacus]

The videos that you do are so impressive and very informative. I have managed to make so many things, especially with plastic injection moulding tools thanks to your videos. Really appreciate your work thank you!

[crazylegsmurphy]

This was amazing. It helped me create a 2-part mold I've been unable to figure out for days.

[bluesinter]

Perfect Lars. Exactly what I need in a week. I have a CNC and need to develop a new part. Thank you.

[nikodotcom]

Dude, Lars, this video was cool. Keep up the amazing work. Are you one of the developers for 360? Also, I can't speak for everyone, but your attention to detail and the explanations about your thought process are more than appreciated, no need to apologize for the in depth analysis. We're all nerds here!

i been using autocad to drawing 3d model (and i am stuck how to create a mold in autocad, it look not easy)but after your video i know more about fusion 360 mold create and your video so clearly to tell me how and why to do it(think i will import stl to fusion then create a mold), hope i can finish my own project soon and smoothly with keep watching your video.

Great to see this mold tutorial. I was a moldmaker myself for about 15 years (1990-2005) and in the late 90's we used Cimatron, with is really really fast to design mold as it was concentrated on mouldmaking. Including the electrodes designing, parting surfaces, inserts, ejection rods, cooling circuit, also the CAM etc. So when I saw you had to wait 4 minutes to devide the blocks i'm wondering how to proceed to build a complete mold with all the parts, electrodes, cam programs etc. In Fusion360. Hope to see more of video tutorials in that direction by you. Thumbs up for thisone.
Another thing I'm missing in Fusion360 is the standard hole creation like for bolts witch connect to or more pieces together to be able to make in a few clicks f.i. M12 to hold the insert in the moldblock.
Same to add ejector pins in that mold with all the thru holes and chamfers, the pin itself.
Is there a way to select a point and add a bolt to 2 or more pieces including all the correct holes for all the parts?

[jerwoolman]

Thanks for all the videos Lars! You've been a great learning resource for me for sure! I think for me coming from Solidworks and using mold tools, Fusion 360 seems to be a bit smarter than solidworks for creating shut-off surfaces and parting lines. Most of the parts that I've split in Solidworks needed a lot of special manual operations and were not easily split with the mold tools. In this respect creating all of the parting surfaces in fusion in my opinion is much easier than in Solidworks.

[jairosan]

Thanks Lars. I will use this technique to create a fixture for a second op. The part is concave and I don’t have another way to hold it but double sided tape

[josehorta]

Hi Lars. First of all thank you for sharing all that knowledge. Definitely I've been learning so much with your videos.
About the plastic parts and shrinkage - should we scale the whole part uniformly or we should differentiate along the mold opening direction, or any other particular rule?
Once more thank you for all your sharing.
Cheers.

Damit. 3days before this video and it would safed me so much time. Thanks for your re video Lars

[meherabhossain]

I was looking for it for a while and got it A LOT

[joaopcrodrigues]

Hello Lars, thanks for the video, but I might have missed something. I have my piece, filled the holes, created the surfaces (even combined them into a single surface, I created the block, but in the Boundary fill, after selecting the block and the surfaces, I only get two little grey cubes. If I understood correctly, I should get three, one for the object cavity and two for each mold. Is there any trick? Should the surface get any thickness?

[mohitajay]

Hello lars, i was wondering if I could get my hands on the model you used in this video. It would really be helpful to have it as an exercise. Thanks in advance!

[loganmarriott]

Thank you, I’ve been looking for details on abnormal parting lines.

[SuperRistopaha]

Hi Lars,
thanks so much for this video, I just got around to watching it now. I have two questions:
1. Is there a way to use the draft analysis tool to help you in locating your parting line position directly or is it more like a helper tool to let you think about where you will place the parting line but in the end you have to place it based on some geometry? Hope that makes sense?
2. Did I miss something or what is the specific reason for using the boundary fill tool in the end? Would it be possible to do a normal extrude ->> up to surface on both sides of your part / parting surfaces?

Thanks and keep up the good work!

[neilcunningham]

Lars... Question I need to make reverse Geometry of a body. Not making a mold I am needing to make a drill jig/holder for a body., The left and right sides bolt together through the body. So how would i do this?

[derricksalmon]

Have not been able to find the livestream for patch/surfaces. Can you tell me which number it is?
Thanks - always inspired by your insights

[UpswingRC]

Thanks Lars, you solved a problem that bothered me for a long time.
