I'm sure all they had to do was alter an ejection knockout pattern, maybe tweak a sprue radius, sprue bushing, maybe change out some water fittings. I think maybe they added some air poppets. Nothing major at all, and nothing that affected the shape of the discs at all. I listened to the lab report on what was going on, and based on my considerable experience in the field, I had a pretty good understanding as to what they are saying.

The differences in the discs are 99% caused by new processes on new machines. Nothing from actually retooling a mold.

I hope you are right. From what it sounded like to me though, there were a few discs they weren't happy with the flight of, and wanted them to be more "as intended". The Volt was one of those, that had gotten much more understable than intended. Molds break from time to time, I'm guessing variations in the molds over the years caused it to actually be a little different, and they returned it to its intended flight.

But it's also hard to see with the Crave. PP Craves almost always (with a very few exceptions) had 0 turn, yet when they added flight numbers, they had -1 turn. Seems like MVP didn't want the Crave to fly like it always had. I can't imagine them using the same mold if they wanted it to fly differently. In either case, it doesn't seem to me that they'll be fixing the Crave to have 0 turn, since they stamped -1 on the plate, so I'm still going to be mad at them for it.

By me proceses, are you talking cool down times? Injection speed? New plastic formulas? I wish DG companies would film more how it's made videos. I wanna see behind the curtains.

down 2 my last 2 Clashes (they are new so hopefully won't need to replace for a while) what is a good replacement for them when the time comes.

All of the above, probably. Clamping pressure is another one. Switching parameters from one type/brand/style of machine to another isnt always straightforward, either.

I'm guessing that was all due to parameter changes. Not saying the couldn't have or didn't tweak the actual geometry of the disc, but I'm guessing it's highly unlikely. It's expensive and somewhat risky to make modifications like that for something fairly trivial.

Also.....short of dropping a bomb on it, molds usually don't just "break". Unless they were the cheapest made aluminum things ever. Which I'm guessing MVP knew better than to do. Or that have a billion shots on them. The shop I used to work at had a mold built in the early 80's, that pumped out several thousand parts a year and was still kicking. Ugly as sin, but pumped out parts.

The notion of a mold breaking beyond repair just from normal cycles is incredibly unlikely. I've even seen one dropped, 3 separate times, from a height of probably 30 feet, onto a concrete floor. Basically just sustained cosmetic damage and a minor bent guide pin. Mold was fine.




Never made discs, but I'm happy to try and "peel back the curtain" as best I can as far as molds and injection molding goes.

They did spend a giant amount of money on some climate control for the new Factory. They did share a post about that

I might be remembering incorrectly, I thought I saw someone on the MVP Facebook talk about a mold breaking, but that might have been a guess and not real data.

But thanks for the insight!

I mean, it's not impossible. I just don't know really how it happens, without some seriously shoddy toolmaking. You're talking a several hundred pound chunk of steel. Things can break, (like ejector pins or slides or things like that) but it's hard to foresee anything breaking beyond repair. Again, unless they had a suuuuperrr cheap prototype mold built or something.

But it's hard to say for certain. I'm just taking educated guesses.


And you're quite welcome! I love to geek out on this stuff whenever I can haha.

Mine flies very similarly to my Servos. But from the description, I do feel like my Clash might be a little more neutral than the target stability. It takes a very leisurely approach to fighting out of a turn. The newer Servo (have both with and without flight numbers) might even be more Clashy than the Clash if we’re going by the ideal.
