Types of Forgings
- Open-Die Forging: Transform metal with ease by employing open-die forging, where metal is skillfully deformed between flat or contoured dies. This method is perfect for crafting large, simple shapes while offering excellent strength and ductility.
- Closed-Die Forging: Achieve intricate designs with closed-die forging, where metal is enclosed within a die cavity, effortlessly taking on more complex geometries with tighter tolerances.
- Hot Forging: Forge forward with hot forging, where metal is heated above its recrystallization temperature, facilitating easier deformation. This method is a staple for large-scale production.
- Cold Forging: Strengthen your products with cold forging, where metal is shaped at room temperature. This enhances strength through work hardening but requires greater force.
Process
The forging process typically involves several precise steps:
- Heating: Begin by heating the metal to the ideal temperature, preparing it for the forging journey.
- Shaping: With precision, shape the heated metal using advanced mechanical presses or hammers, defining its new form.
- Cooling: Allow the shaped part to cool naturally, followed by optional heat treatment to enhance properties.
- Finishing: Elevate the forged component with finishing touches like machining or surface treatment, achieving the desired final specifications.
Dimensions
Forged components boast a wide range of sizes, from petite fasteners to grand structural parts. Standard dimensions span from mere millimeters to several meters, tailored to each unique application.
Applications
Forge ahead with confidence as our forgings are essential in industries like aerospace, automotive, and construction, prized for their unparalleled strength, durability, and reliability.
