In the industrial world, various types of manufacturing processes are being used to convert raw materials into finished products. Manufacturing processes are generally designed in such a way as to produce high-quality products and services at competitive prices, ultimately satisfying the customer or end-user requirements.
The manufacturing processes are broadly classified into two types:
- Primary Shaping Processes
- Secondary Forming Processes

Primary Shaping Processes
The following manufacturing processes come under this:
- Casting Process
- Forging Process
- Rolling Process
- Drawing Process
- Extrusion Process
- Bending Process
Secondary Forming Processes
The following manufacturing processes come under this:
- Machining Process
- Surface Finishing

Heat Treatment Processes
Heat Treatment is the property enhancement process that provides the desired strength to the metal or casting products. The following heat treatment processes come under this:
- Hardening
- Tempering
- Normalizing
- Quenching
- Ageing
- Carburizing
- Case Hardening
Machining Processes
The various machining process carried out to remove the metal to give the final finished shape to the product.
- Turing
- Drilling
- Shaping
- Grinding
- Milling
- Boring
- Reaming
- Facing etc.
Surface Finishing Processes
- Buffing

Manufacturing Process Casting
The casting manufacturing process is broadly classified into two categories:
 1) Ferrous Casting Processes- that contain Iron as the main constituent.
For example Sand Casting, SGI Casting, CI Casting, etc.
2) Non-Ferrous Casting Processes – that do not contain Iron as the main constituent.
For Example Aluminum Die Casting, Zinc Die Casting, and Copper Die Casting.
