Precision Hot & Cold Forging with Integrated CNC Machining
At Weforging, we specialize in both hot forging and cold forging processes, producing high-strength forged components for demanding industries. Our expertise covers large gear blanks, flanges, piston rods, and industrial fasteners, ensuring exceptional toughness, dimensional accuracy, and consistent quality. With advanced CNC machining integration, we deliver complete forged solutions trusted by OEMs across automotive, energy, marine, and heavy machinery sectors.
What Is Hot Forging?
Hot forging is a manufacturing process where metal is heated above its recrystallization temperature, typically between 900°C and 1250°C, and then shaped under compressive force. This high-temperature process allows the material to flow easily into dies, producing parts with improved grain structure, high toughness, and superior fatigue resistance. Hot forging is especially suitable for large components such as gear blanks, flanges, shafts, and heavy machinery parts, where strength and durability are essential.
What Is Cold Forging?
Cold forging is performed at or near room temperature, using high-pressure dies to shape the metal without heating. Unlike hot forging, this process provides exceptional dimensional accuracy, smooth surface finish, and significant material savings. Cold forging is commonly used for fasteners, small shafts, pins, and precision connectors, making it a cost-effective choice for high-volume production. Additionally, cold forging increases material hardness through strain hardening, ensuring long service life and reliable performance in automotive and industrial applications.
