Hi Jesse! Injection molding process technician here. The sprue bushing is made as an insert for probably a few reasons. Chief among them, you could try different bushings with different size sprues/gates. That would affect pressure loss and gate seal time which can change a myriad of different aspects of the part. Also, if any part of the sprue or where the nozzle mates to the bushings is damaged, it is easier and cheaper to fix.
Man as a mold maker watching you guys take this apart was pure entertainment. Sometimes you've just got to hit stuff with some oomph. Brass hammers will be your best friend
As a disc golfer who used to work in the Automotive industry, specifically Thermoplastics and interior components, I thoroughly enjoyed this video. It gives additional appreciation for what you guys and gals do, and how difficult it is to make a professionally approved disc. Cheers
Bro that’s just nuts! Thanks for the behind the scenes look. The word that keeps coming to mind is grown-up. From learning to weld in your garage to dealing with 700lb molds and lots of words I don’t understand… what a journey!
Thank you for this video very cool to see the molding process keep up the good work you've come such a long way from your garage man it's awesome to see
My guess is that MVP doesn't have the injection circle because they are using that center mold on multiple disc. Example. Envy and proxy have the same center but different gyro rim mold
Jesse, how do I DM you? I don’t see an email address and I don’t have instagram. I am an engineer that specializes in injection molding. I was going to offer my email or cell number. I can probably save you some frustration if you run into problems. I am an avid disc golfer, and would love to offer any help. I could have helped you out with the different standards of date stamps lol. Also, MVP uses what is called a hot runner. Basically they keep the nozzle hot at the point of injection into the part. So there is no sprue to trim/regrind. I’m sure you have engineer contacts that helped produce the mold, but I’m someone who won’t be annoyed being texted at odd hours to help troubleshoot. I know what’s it’s like to be new to molding and getting going from scratch is tough. Would be happy to help if I can be of use!
Cool insight. I hope we get to see it in action. Kind of weird how you were both fumbling your way around it like you’d never seen it before or it was some sort of alien artefact with no instructions.
Having worked in a rubber molding plant for 22 years I can so relate to the chain adaptation. I can't tell you how many times a new mold would come in and the operators first response is... what kind of an idiot engineer designed this? Sometimes it seemed like they had no clue how a press worked. So... back to the machinist for jerry rigging your $25,000 mold.

An expanded diagram would make a BADASS T shirt!

Yes! This is Awesome! I've always wanted to see this much detail!

Dunno if anyone told you this yet, but these videos have a real SmarterEveryDay vibe, and you even look quite a bit like Destin.
I love this kind of stuff!

I think MVP uses hot runner for the overmold but the substrates definitely look like they have a cold sprue that is cut off.
This is really interesting and mindblowing. I cant help to think who built this machine and how?
This was fun
Great insight! Thank you TrashPanda!
I am not sure how to approach this, but man do I wish I was part of these processes... The nerd in me needs this 😅
The videos are the best!
I have been waiting for this

Had me nervous in the hook when I saw you working the file on an expensive piece like that. It's hard to put the metal back on 🤣
I worked in a plastic factory briefly 20 years ago can confirm it gets old real quick but cool to see the design side
Do you have any other new disks in the works?, I think a name like the Aether would be cool, I’ll 100% be buying whatever you come up with in the end.
I’m still building molds on the floor at the shop I work at lol hurts my back.. was promised a table but it hasn’t come yet
With such an important piece, I'm surprised there aren't torque specifications for bolts and an order in which to torque.
Rocking the velcro Janoskis sick favorite shoe ever
You all need to AI in Mike Rowe style voice over in the montages!
Awesome...
I'm guessing that the sprue bushing is for different nozzle sizes, higher flow rates, or something like that, though I could be completely off mark.

I understand you are a small shop. Generally not a good idea to PM your tools on the floor.
I dig it.
Could use more Jesse Pinkman, but otherwise awesome information!
