Cool projects that you have done.

Nothing special just a plastic injection mold with +or- .001 tolerance.

@Whisperfan, if I didn't say it before, I'll do it now, or again... your rests are beautiful pieces of work. I know the care and effort that went into them. And the crisp corners, the knurling, fit & finish, everything associated with the adjustments, reminds me of fine Swiss tooling and fixturing. You can be very proud!

@EoD; always loved mold work. Love the way the female cavity is brought to an insane finish. You could take those molds and frame them, put them in a museum. Awesome work.

One thing it reminded me of... there was a guy on eBay years ago - he may still be there - that sold the aluminum cuts, odds & ends, that went into those molds. They called it "fortal" aluminum, basicaly 7075-T6. He sold boxes of assorted pieces for pretty cheap, and that s--t is GLORIOUS to machine and makes some truly awesome parts. It's my favorite metal, bar none.

I've turned mold aluminum into that sharpening machine I posted earlier, turned it into guns, many, many other things. Made me a fan of 7075 in general.

Q for you... are those shallow channels cut to expel air from the mold during filling?

[Eyes Of Death]

Baffled Yes the .001 DOC are the air bleeds. This mold is hard to set up and run. I think i need more or wider air channels. This mold runs LDPE and it flashes with to much injection pressure.

And this is the Fortal 7075

Thanks! Is there a significant difference between the "Fortal" aluminum, and regular ol' 7075-T6?
