Powder Metallurgy Gears
A versatile family of PM precision power-transmission gears for mass-production, high-reliability mechanical systems — spur, helical, worm and internal profiles with built-in splines, hubs or cams.
- Materials
- Iron-based, alloy steel, stainless steel and specialty PM powders
- Features
- High wear resistance with controlled porosity, stable tooth-root fatigue strength, quiet meshing, steam treatment/infiltration/heat treatment options, extremely stable batch dimensions
- Application
- Industrial automation and servo systems, automotive actuators and small transmission modules, home appliance drive systems, printing and scanning machinery, robotics and precision instruments.
Frequently Asked Questions
What materials and process are used for Powder Metallurgy Gears?
Powder Metallurgy Gears is made from Iron-based, alloy steel, stainless steel and specialty PM powders and is formed by MIM/PM (metal injection molding / powder metallurgy) near-net-shape and sintered to a relative density of ≥ 98%, which keeps mechanical properties close to wrought material.
What tolerances can Powder Metallurgy Gears hold?
Typical as-sintered dimensional tolerance is ±0.3–0.5% of the dimension. Tighter tolerances are achievable with secondary sizing or machining, agreed per part during quoting.
What is the MOQ and lead time for Powder Metallurgy Gears?
MOQ is 1000 pcs. Mold lead time is about 20 days (mold fee typically RMB 20–40k depending on part geometry), and production lead time is about 7 days once the mold is validated; secondary processing adds 3–5 days.
