Drop forged hydraulic cylinder yoke

Drop forging, also called closed die forging is a metal shaping process where a heated metal billet is placed between dies and struck by a hammer or press to form the desired shape. It is commonly used for high-strength components like hydraulic cylinder yokes, connecting rods, gears.

The hydraulic cylinder yoke is a critical component that connects the cylinder to other heavy-duty machinery, such as construction equipment, excavators, loaders, cranes, agricultural machinery, tractors, harvester, mining & industrial hydraulic lifting equipment.

Close die forging or mold forging process
Material Selection	Choose the appropriate metal (e.g., carbon steel, alloy steel, aluminum, or titanium) based on the component’s requirements. Ensure the required steel meets the required chemical composition and quality standards. Baoding Guokun will test the material’s chemical composition before storage. Baoding Guokun has years of experience working in the following grades of carbon steel, alloy steel and stainless steel. We are able to drop forge almost every type and grade of carbon steel material available on the common market, such as 4140(42CrMo4), 8620, 1018, 1035 or C35, 1080, 4340, 1137, etc.
Billet Preparation	Cut the raw material into billets of the required size. And heat the billet to the forging temperature (typically 1100°C–1200°C for steel) to make it malleable
Die design and preparation	Design the dies (upper and lower) to match the final shape of the component. Dies are typically made from high-strength tool steel and are precision-machined.
Forging	Place the heated billet into the lower die. Apply pressure using a hydraulic or mechanical press to force the metal into the die cavity. The metal fills the die, taking the shape of the mold
Flash Formation & Trimming	Excess metal, called flash, flows out of the die cavity through small gaps. Remove the flash and excess material using trimming dies or machining
Cooling	Allow the forged part to cool slowly (for some materials) or control the cooling rate to achieve desired properties.
Heat Treatment	Perform heat treatment processes like normalizing, quenching, and tempering to enhance mechanical properties (e.g., hardness, toughness)
Finishing	Machine the forged part to achieve precise dimensions and surface finish. – Apply surface treatments (e.g., sand blasting, coating) if required
