Types of Forgings
- Open-Die Forging: Experience the robustness of our Open-Die Forging, where metal is artfully deformed between flat or uniquely contoured dies. This method excels in crafting large, uncomplicated shapes, delivering exceptional strength and ductility for your demanding applications.
- Closed-Die Forging: Our Closed-Die Forging is a masterpiece of precision engineering, enclosing metal in a die cavity to shape it with unparalleled accuracy. This process is ideal for creating intricate geometries and maintaining tighter tolerances, ensuring every detail is flawlessly executed.
- Hot Forging: Embrace the efficiency of Hot Forging, where metal is heated above its recrystallization temperature, making deformation a breeze. This method is the cornerstone of large-scale production, ensuring swift and seamless manufacturing processes.
- Cold Forging: Discover the power of Cold Forging, where metal is expertly shaped at room temperature. This technique enhances strength through work hardening, although it demands higher forces. It's perfect for applications requiring superior strength and precision without the need for heat.
Process
The forging process typically involves several meticulously planned steps:
- Heating: The initial step is to meticulously heat the metal to the precise temperature required for optimal forging.
- Shaping: Next, the heated metal is expertly shaped using highly efficient mechanical presses or powerful hammers, forming it into the desired configuration.
- Cooling: After shaping, the forged piece undergoes a controlled cooling process, often followed by heat treatment to enhance material properties.
- Finishing: The final touch involves additional processes such as precise machining or advanced surface treatment, ensuring the product meets exacting final specifications.
