    plastic extruder barrel and screw made out of grade 7075 aluminium?

    It's been quite a few years since I've worked on extruders, but I don't think aluminum would survive the cleaning process when things go wrong, like a loss of power.

    Hi ALL, can a FPBW in plate also

    I'm retired now, but 30 some years ago I was an AWS (American Welding Society) CWI (Certified Welding Inspector), and there was no Butt Weld, it was a Butt Joint with a Groove Weld. Unless something has changed.
