Automotive Sprockets

Our company specializes in producing iron-based powder metallurgy automotive parts, especially in the production of automotive sprockets, with professional characteristics. Automotive sprockets are essential components in engine timing systems and accessory drives, precisely controlling valve timing and power transmission. Using advanced powder metallurgy technology, we produce camshaft sprockets, crankshaft sprockets, and balance shaft sprockets with integrated features like tone wheels and sophisticated oil passage designs. This net-shape manufacturing ensures dimensional accuracy, material consistency, and optimal chain engagement throughout the engine's service life.

Product Parameter (Specification)

Product Feature And Application

High wear resistance and strength are achieved through optimized material formulation and heat treatment processes, resulting in a tooth surface hardness of HRC 40–60 while maintaining a tough core for excellent impact and wear resistance. Precise tooth profiles and strict pitch tolerances are ensured via precision mold manufacturing, allowing for smooth chain engagement and reduced noise and wear. The design offers flexibility by enabling the single-step molding of complex features such as wheel hubs, flanges, reinforcing ribs, and various shaft hole types, which reduces subsequent processing and assembly costs. Compared to traditional cast or forged components, powder metallurgy sprockets provide weight reduction at equivalent strength, contributing to lower rotational inertia. Moreover, the powder metallurgy process ensures excellent consistency, delivering high dimensional and performance uniformity across all mass-produced sprockets.
