CLOSED DIEFORGING
Controlled Shapes. High Strength. Repeatability.
We manufacture precision closed die forged components with controlled grain structure, high mechanical properties and excellent dimensional accuracy, suitable for critical industrial applications.
OVERVIEW
Closed die forging is a metal forming process where the heated material is placed in a precision die cavity and shaped by controlled high-pressure forces. This process ensures superior mechanical properties, uniform grain flow, high strength and repeatability, making it ideal for critical components.
We manufacture closed die forged components in a wide range of sizes and material grades for pumps & valves, oil & gas, power, heavy engineering, mining, marine and process industries.
