Forged Gears
Songjie Forging is a leading professional forged gear manufacturer based in China, with decades of experience in special steel production and precision component machining. Deploying advanced open-die forging technology, closed-die forging capabilities and seamless ring rolling processes, we control raw material quality directly from steel mills to produce high-quality custom forged gears.
Our forged gears feature continuous metal grain flow lines, outstanding strength, toughness and fatigue resistance. They are the ideal choice for heavy-duty operating conditions including metallurgy, mining, power generation, shipbuilding, rail transit, industrial transmission and heavy machinery. The gears ensure maximum reliability of your mechanical equipment and minimize downtime.
We provide a full-range customized service covering gear blanks through to finish-machined forged gears, supporting a wide selection of carbon steel, alloy steel and special steel grades. All products comply with international standards such as ASTM, JIS and ISO, and undergo stringent quality inspection throughout the whole production process.
