This video showcases Innovation Technology in the transmission component industry: Gear Manufacturing using Iron Powder Press Molding (Powder Metallurgy). We discuss how fine iron powder is compacted under high pressure, sintered, and finished to produce strong, porosity-controlled gear components that are manufactured automatically with high precision and minimal waste.

In the production of gear components for automotive and industrial machinery, mechanical strength and accuracy of the tooth profile are key parameters. This Innovation Technology using Powder Metallurgy (PM) allows for the creation of gears with a near net shape directly from the mold, minimizing the need for expensive machining. PM utilizes highly precise dies and accurate hydraulic pressure control to ensure uniform density in the iron powder, which is crucial for the gear's strength after the sintering process (heating until adhesion). This method offers significantly higher material efficiency than cutting from a solid block.

So, how does this Innovation Technology work? The process begins with fine iron powder mixed with binders and lubricant, which is then fed into the high-precision steel press molding die. The machine automatically applies extreme pressure (up to hundreds of megapascals) to compact the powder into the gear shape, called a green compact. This component is then heated in an atmosphere-controlled sintering furnace, which transforms the green compact into a solid metal gear without reaching its melting point. Robotic automation ensures that the delicate green compacts are handled carefully and at high speed, guaranteeing dimensional precision and quality consistency between gears.

Broadly speaking, Metal Powder Press Molding is an embodiment of innovation in gear manufacturing. It is a technology that provides extraordinary capability to produce gear components with unmatched material efficiency, mechanical strength, and tooth profile accuracy. Its direct impact is on the availability of high-quality transmission components at a competitive production cost for the global supply chain.
