Core advantage

1.  Material and process characteristics

Diverse materials : Using iron, copper, stainless steel or mixed alloy powder (such as Fe-Cu-C, Fe-Ni-Mo, etc.), the material ratio can be customized to optimize strength, wear resistance and corrosion resistance.

Near-Net Shape : Direct pressing, reduce the amount of machining, reduce material waste and production costs.

High density and uniformity : Increase gear density (up to 7.4 g/cm³ or more) through cold isostatic pressing, warm pressing or repressing and refiring processes to ensure stable mechanical properties.

2. Performance advantage

High strength and wear resistance : By heat treatment (such as carburizing, quenching) or surface treatment (steam oxidation, phosphating) to enhance the hardness of the tooth surface (HRC 50-60), extend the service life.

Low noise operation : Precision mold molding ensures profile accuracy (DIN 6-8), smooth meshing, reducing vibration and noise.

Lightweight design : Porous structure can contain oil (oil content 10-20%) to achieve self-lubrication and reduce maintenance requirements.

3. Complex structure adaptability

Can form bevel gears, bevel gears, internal gears and gears with convex/shaped holes in one piece, avoiding the limitations of traditional cutting.

Typical application scenarios
Automotive industry: transmission gear, starter gear, oil pump gear, differential pinion.
Industrial Equipment : reducer gear, motor transmission parts, automatic mechanical drive unit.
Consumer Electronics : Home appliance motor gear, power tool transmission system, office equipment precision gear set.
New energy field : electric bicycle central motor gear, UAV power transmission components.
