Carbide Step‑Type Lower Punch for Powder Metallurgy Automatic Press
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.
Carbide Step‑Type Lower Punch for Powder Metallurgy Automatic Press
Our carbide step‑type lower punch works as a matched die component with step‑type upper punch on fully‑automatic mechanical powder metallurgy presses. It bears bottom‑side compaction and ejection for stepped annular and inner‑hole powder compacts. Widely applied for automotive oil‑impregnated bearings, gear blanks, flange rings, as well as new‑energy related annular powder‑based parts.
Multi‑step end faces replicate the bottom profile of target workpieces. Central through‑hole accommodates core rod for inner‑hole forming. High‑precision surface finish reduces wear and guarantees stable green‑part quality in multi‑cavity or large‑tonnage single‑cavity mass‑production.

Features
- High Wear Resistance: Premium cemented carbide substrate resists abrasive powder erosion, extends service cycle under continuous pressing.
- Multi‑Step Profile Accuracy: Multi‑level step end face precisely reproduces bottom contour of annular compacts for consistent part geometry.
- Reliable Ejection Performance: Optimized flatness and surface finish enables smooth green‑part ejection without scratching or chipping.
