Steel wind turbine forging axis, forged shaft
Forging is manufacturing process where metal is pressed, pounded or squeezed under great pressure into high strength parts known as forgings.
The forging process can create parts that are stronger than those manufactured by any other metalworking process.

Open Die Forging / Hand Forging
Open die forgings or hand forgings are made with repeated blows in an open die, where the operator manipulates the workpiece in the die. The finished product is a rough approximation of the die. This is what a traditional blacksmith does, and is an old manufacturing process.
Open-Die forging
Characteristics of Open Die Forging
Merits: No special tools(cost, fabricating time)
Simple forms
Problems: High machining costs
Material not optimally used
Grain flow (fibre structure) not optimal
Applications: For low production series
Test samples and prototypes
Especially Large dimensions
Alloys: Mainly medium to high-strength materials
Impression Die Forging / Precision Forging / Closed-Die forging
Impression die forgings and precision forgings are further refinements of the blocker forgings. The finished part more closely resembles the die impression.
