Closed Die Forging

Closed die forging (impression-die forging) is a controlled manufacturing process where heated metal is placed between precision-engineered dies and shaped under high compressive force.

Unlike casting or fabrication, closed die forging refines the internal grain structure of the material, aligning it along the geometry of the component.

Performance Advantages :

Superior Mechanical Strength

Higher Fatigue Resistance

Improved Impact Performance

Dimensional Consistency Across Batches

How Vinir Stands Out

01

In-house die design and machining for controlled geometry

02

Hammers from 1T to 12T and hydraulic presses up to 3000T

03

Integrated heat treatment and machining under one roof

04

Structured process control for high-mix, low-volume programs

05

43 years of forging expertise across regulated industries
