High-density Gear
High-density PM gears for automotive, industrial and precision motion systems — uniform density, superior wear resistance and high fatigue strength with near-net-shape complex tooth profiles.
- Materials
- Proprietary iron-copper PM powders
- Features
- High-density uniform microstructure, helical/bevel/spur profiles with tight tolerances, low-noise meshing, optional surface treatment or impregnation, scalable high-volume production
- Application
- Automotive transmissions (gear trains, differentials, timing components), industrial motors and actuators, robotics and precision machinery, household appliances and office equipment, power tools and conveyors.
Frequently Asked Questions
What materials and process are used for High-density Gear?
High-density Gear is made from Proprietary iron-copper 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 High-density Gear 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 High-density Gear?
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.
