Carbide Step‑Type Lower Punch for Powder Metallurgy Automatic Press for Annular & Inner‑Hole Compact Forming
This cemented carbide step‑type lower punch matches with upper punch set for fully‑automatic powder metallurgy presses. It supports dry compaction of stepped annular and inner‑hole green compacts, for mass‑production of oil‑impregnated bearings, flange rings and new‑energy powder‑formed components.
