Cutting is a crucial step in metalworking, ensuring the material is prepared for further fabrication, such as welding, bending, or machining.

4. Forming (Bending, Rolling) Definition

Forming is a metal fabrication process that changes the shape of metal without removing material. It includes bending, rolling, stamping, and forging to create curves, angles, or specific designs. Bending is done using press brakes, while rolling shapes metal into cylindrical or conical forms. Forming is used in industries like construction, automotive, and aerospace to produce structural and functional metal components.

5. Casting Definition

Casting is a metal fabrication method where molten metal is poured into a mold and allowed to solidify into a specific shape. It is commonly used to produce complex and large components that would be difficult to manufacture through machining or welding. Various casting methods include sand casting, die casting, and investment casting. Industries such as automotive, aerospace, and machinery manufacturing rely on casting for mass production of metal parts.

6. Punching Definition

Punching is a metal fabrication technique used to create holes, slots, or other cutout shapes in sheet metal. A punch press applies force using a punch and die set to remove material in a precise pattern. This process is widely used in manufacturing metal enclosures, brackets, and decorative panels. Punching is highly efficient for mass production, ensuring uniformity and accuracy while reducing material waste.

7. Shearing Definition

Shearing is a metal cutting process that removes excess material by applying a high-force blade to make straight-line cuts. It is primarily used for cutting sheet metal, plates, and bars without melting or chipping the material. This method is widely used in manufacturing structural metal parts, automotive panels, and HVAC ducts. Shearing ensures clean and precise edges, making it an essential technique in metal fabrication.

8. Stamping Definition

Stamping is a metalworking process that uses dies and presses to shape or emboss sheet metal into specific designs. It includes operations like blanking, bending, coining, and embossing. Stamping is commonly used for producing large quantities of metal parts, such as car body panels, electronic components, and appliance casings. The process is cost-effective, fast, and ensures high precision, making it ideal for industries requiring mass production.
