I was commissioned to make an injection mold for a guitar pick by Justin from NEO Guitar Concepts. At the end of the video, you'll see Justin playing the guitar with one of these picks. I show how I modified a guitar pick CAD file supplied by Justin, designed the injection mold, made the injection mold, and then molding some test guitar picks.

These are extremely helpful videos that demystifies injection molding prep work that is mostly skimped over by a lot of instructional videos.
So cool to see a guitar pick made in such a detailed fashion. Thanks for the video.
Amazing how much clamping force is needed just for a little part like that.
Very fancy
Enjoy these mold projects
Great video John! Makes me wanna make my own mold and try it out. Thanks for the information on the clamping pressure - that will come handy!
It's a rule that has helped me a lot.
Very interesting video. So many details.
It is bizzare in a good way that there's a channel on youtube about designing injection molds.
I finds it amazing that so many people watch. Thanks!
Realy helpful
Nice product design and fab overview!
Thanks, Dave!
Nice to see from design-programming-milling-injection to finish product.
Thanks.
Well done!!
I find all this fascinating! Great work.
Brilliant presentation! Very nice work. Fusion looks like a blast to use. I'm stuck in NX at work but I may give it a shot here at home.
Fusion is nice, but not as nice as SolidWorks. I do, however, love the CAM in fusion.
@@JohnSL solidworks was my bread and butter through school and I still own a license. I just wish it crashed less often 🙈
❤very nice
👍👍Thanks a lot sir for sharing this video so please keep uploading video like this. Can u make one video with derail what runner, subrunner and gate size shiuld me.
Great video!! Thanks for the great content
Awesome! We've been talking about making guitar picks at some point too... Not sure if there's any money in it, but it would be a fun experiment.
I'm not sure either. But it was fun.
Another way you can find the surface area in fusion360 is to select the body or component and right click.
Then select Properties and the surface area is physical tab under area.
Is there a rule of thumb for calculating the largest surface area you can inject into?
For example, What if the volume of the pick was the same, but the surface area much wider and longer. Surely there is a limit to how far the plastic can travel in the mold, even if it's still within the shot size limit?
The rule of thumb is based on the cross section rather than the surface area of volume. That's because it's the cross section in the same plane as the parting line that creates the pressure trying to force the mold halves apart. The rule of thumb that I learned is 2-2.5 times the cross section.
Great video!
But I have to ask, that guitar pick has a big deep rectangular recess in it, what is that for?
Just seems weird because it is probably not the most ergonomic shape for grip. Does something go in the recess?
I was wondering that as well, and honestly don't know the answer. It's what the customer supplied and ask for.
👍👍👍👍
Nice video ! This rule of 2,5 times… works for how much injection pressure ?
It's a general rule of thumb and I haven't found corresponding injection pressures that go along with this rule of thumb. Now I'm curious. I'm going to need to try out some mold flow simulations to see what they say.
Where can I learn how to make aluminium mold
I have other videos. If there is an aspect I haven't covered, let me know and I'll see if I can make a video.
John really need your help
I wish you where my best friend im machanic iron worker and run into so meny times i need somthing made that you could make
Why is it that a person like me! “With a Brain injury” that has worked in FRP by myself 12+ years. can’t find the help to grow? Or someone as yourself Sir? I love all that you do and only dream of what I could have been! But I really wish someone would look at me?
