I'm not familiar with the term "Pinnacle Die", but your pictures look what I would call a "Steel Rule Die" if it's thin rule in wood or a "High Die" if it's a thicker rule made entirely of steel. Either way, they're cutting by compression against a sharp edge. Holes are typically "tagged" by grinding a small void in the cutting edge in a few places so the scrap stays in the part until it's manually removed after it's out of the die. The raised edges are inherent in the cutting process since the material has to go somewhere. Reducing the cutting angle may help, but the dies will not last as long. Ejection rubber around the outside may help, but I doubt it.
Good Luck,

Using steel rule dies rather than your "pinnacle dies"(I'm not familiar with that term, but I think I know what you refer to) would solve most of your problems. These use thin cutting blades with sharp cutting edges, which are embedded in a plywood sheet to form the cutting shape. The sharp edged blades displace very little material when cutting, which is what causes the raised bumps on cut edges. This can be further minimized by using single bevel blades rather than double bevel. A single bevel will displace material to only one side of the cut, which can be your trim waste.

Foam rubber pieces are usually strategically placed next to the blades to clamp the material while cutting and to eject the cut pieces from the cutting die.

I have been surprised by how low cost these dies are as well as their precision and productivity. The shapes are created by laser cutting slots in the plywood that holds the blades. Pinnacle dies are more robust for tough and thick materials like leather.

You could possibly try some sort of vacuum fixture that'll pull all the chad away from the die.

Yes, steel rule die. Called "Label die" here http://www.sharpdie.com/?page_id=912

A Pinnacle die is one that is made from a single sheet of material, with all but the cutter etched or milled away. This is more flexible than steel-rule dies, but seems to have the problem of a wider cutting angle.

Given the way they are made it may be difficult to deal with because the adhesive is probably being transferred to the die. Maybe there's a compatible wax or other release that will prevent the adhesive sticking.

Pinnacle die is different from steel rule. I appreciate the suggestions guys, but I can't just change all of our tools from pinnacle to steel rule :/

could you elaborate on that?

Quote (3DDave)

got any ideas on waxes?

1. Steel rule dies are sometimes fitted with small stiff coil springs to eject waste.
I suppose you could use a simple port and a timed air blast.

2. Does that mean it's time to sharpen your pinnacles or replace your platen?
Or increase the counterpressure or replace the cushion under the platen?
