Default What is a microbead?

What is a microbead on a disc, and can it be confused with extra plastic extruded between mold pieces? Because I may have misunderstood something I read in this forum and removed a microbead thinking it was extra plastic on a DD Defender. But I don’t know....

Md3 is a pretty good example. Its a bead but just very small. And vs. flashing (the extra plastic that shouldnt be there in a perfect world), the flashing will usually be much sharper. It should be pretty clear what is trimmable and what isnt.

Flashing and micro beads can be difficult to tell the difference. I think the early Gators had a micro bead as well as Aviars and Stingrays.

Does an FD have one? Or is that sharp edge the flashing?

If it’s a sharp edge it’s probably flashing, if it bumps out horizontally at all that’s probably a micro bead.

Flashing sands paper off pretty easily a micro bead does not.

Ok. This was not a microbead, it was the flashing. Razor sharp, invisible edge on the inside lip of the rim.

Someone said the Harp has a microbead. I throw the harp and wouldn’t know it has one. Looking at it right now I don’t know what I’m looking for.

This is a big bead on the rim, the micro bead would be the same thing but much smaller.

If it's so small you aren't sure whether it was a purposefull feature of the mold versus flashing from the molding process, I'd guess it's flashing, though a few molds are questionable. Like, why design a tiny linear burr on the edge of the disc? Anything smaller than the Voodoo's bead, and I'm calling it squish out, maybe from ill fitting plates or worn out ones.

Wizard (big bead) vs Voodoo (micro):

I don't think it's easy to confuse flashing and beads. The bead is designed into the disc, as others have shown. A micro-bead is a really small bead, or sometimes a little nuiance in the wing that feels like a bead. (Others have mentioned examples, but my personal favorite is the Predator.)

All the flashing I have seen extends vertically, down toward a table or the ground if you set the disc flat. The horizontal line your disc shows is what is called the "parting line," or the residual area of plastic between the top and bottom components of the mold. To be honest, I don't know where that flashing comes from. But, in general, flashing is inconsistent around the 360 degrees of the disc. Again, it extends vertically, whereas the "bead" or micro-bead is more of a horizontal feature--i.e. you feel it best by feeling horizontally along the wing down toward where it would be sitting on the ground.
