Our Roll Forging Process
Each stage of our roll forging process is carefully controlled to deliver high-strength parts with excellent dimensional accuracy and minimal material waste.
Raw Material Selection
We source high-quality billets or bars with specified chemical compositions and mechanical properties tailored to customer requirements.
Cutting & Heating
The raw material is cut to the required length and uniformly heated(between 980°C and 1300°C) in a controlled environment to achieve optimal plasticity for deformation.
Roll Forging Operation
Heated billets are passed between rotating grooved rolls. The material is progressively compressed and elongated to achieve the desired shape and profile.
Controlled Cooling
After forging, parts undergo a controlled cooling process to relieve internal stresses and ensure consistent metallurgical properties.
Heat Treatment (Optional)
For enhanced performance, we offer tailored heat treatment options such as normalizing, quenching, and tempering, depending on the application.
Machining & Finishing
Forged parts may undergo CNC machining to achieve tight tolerances. Additional finishing processes ensure surface quality and dimensional precision.
