anyone used PHENOLIC before
Hi am making profile dies for pullmax type machine they are 0.5x2x2 i would like to find material where dont live tooling marks in steel or aluminum , but strong enough to move 18 gauge metal , delrin is little to soft for more pronounce shapes that i would like to archive i wonder if anyone used phenolic material or any other stuff that would work that type application
i wonder what material Stan Fulton using for his aluminum tumbnail dies . Thanks ! |

Don't know what kind of die you are making but I have used PVC with success on stainless steel. You still have to watch the feed rate and the speed. The dies I made were used in a Nadia style holder. UHMW also works well on steel and aluminum without marking, it is a little softer than the PVC. You can get a better finish on the dies made from PVC. They sand very nicely.

Phenolic is pretty tough stuff for sure. In the business I spent a bunch of years in, we used it for wear points, that is to reduce wear on surrounding components. Never really used it for tooling there as it wasn't very inexpensive and we were cheap. I'd categorize it as one of, if not the, hardest plastics out there. Harder than bone and harder than acrylic. But it's so strong it won't shatter. Mills like aluminum to me but stinks a bit during milling and real bad during sanding.
It'll loose it's sharp edge about like aluminum, but holds it better than wood I think. I'd think it would hold up for short runs like a person would be doing in the hand metal shaping business. Would be real good with rounded edges.

Sollis, are you trying to make trim as in bright work on a car? Are the die to fold over the underside to hold the clip in? If so the PVC is not strong enough to do that, at least not with stainless. The metal will try to dig into the die material. It does work well to form the shape of the molding.

I worked with some phenolic years ago. I may be wrong but I remember it as being very brittle.

McMaster Carr stocks various grades of phenolic material. The G-10, G-11 stuff is epoxy and glass cloth. Machine this stuff with carbide. The linen cloth reinforced material is not as strong but easier to cut. I think that either material would work well for forming tooling. The cloth matrix makes it not brittle. I've used this material to make production tooling for machining operations. It can be drilled and tapped and the threads stay usable for many cycles. The material is similar to circuit board plate.

I got that material today I just made quick die to see what it would to this is 1/4 step worked good and die hold up good ,the material 60 thousand, but man its stinks when you grind that think I learn aluminum file works good to shape contour
