Planetary Gear

Planetary gears are the core transmission components of the planetary mixing system in kitchen mixers, responsible for transferring power from the central sun gear to the mixing tools. Our powder metallurgy planetary gears feature an optimized tooth profile design, ensuring smooth transmission under high-speed and heavy-load conditions. Special surface densification treatment and food-grade lubricant impregnation processes enable the gears to maintain excellent performance even in humid kitchen environments.

Product Feature And Application

Powder metallurgy pressing is a high-efficiency, near-net-shape manufacturing process for metal parts, ideal for mass-producing high-precision, structurally complex components. Its core advantages include:
（1）Material utilization exceeds 95%, with almost no machining waste, aligning with sustainable manufacturing principles.
（2）Suitable for mass production, ensuring stable part dimensions, uniform mechanical properties, and strong quality control.
High Precision & Good Surface Quality
（3）Achieves high dimensional accuracy in a single pressing (typically IT7-IT9 tolerance), with excellent surface finish, reducing the need for secondary machining.
Ability to Form Complex Geometries
（4）Capable of producing parts with steps, curved surfaces, tooth profiles, and irregular holes ( gears, gear rings) through precision mold design.
（5）Allows optimization of hardness, wear resistance, and strength by adjusting powder composition, ratios, and post-treatments (e.g., carburizing, sinter hardening).
Application Examples in Household Mixer Accessories
The transmission system in household mixers requires low noise, high wear resistance, smooth operation, and controlled costs. Powder compaction molding provides an ideal solution for such precision gear components
