Forging Introduction

Forging is the name for processes in which the work piece is shaped by compressive forces applied from dies and tools. It is one of the oldest metal working operations dating back all the way to 4000 B.C. Simple forging can be done with a hammer and anvil, as in a blacksmith. Most forgings however, require a set of dies and equipment such as a press.

During forging operations, grain flow and grain structure can be controlled, thus forged parts have good strength and toughness. Forging can be used to manufacture highly-stressed critical parts, for example, aircraft landing gears, jet-engine shafts and disks. Typical forging parts we have been doing include turbine shafts, High Pressure Grinding Rolls, gears, flanges, hooks, and hydraulic cylinder barrels.

Forging may be done at ambient temperatures (cold forging), or at elevated temperatures (warm or hot forging, depending on the temperature). At Rongli Forging, hot forging is more prevailing as it is more cost-effective. Forgings generally require additional finishing operations such as heat treatment to modify properties and machining to achieve more accurate dimensions.
