Forming

In the forming stage, the prepared sheets are reshaped into the desired forms using various techniques:

Bending: Achieved through brake presses, bending transforms flat sheets into specific angles, typically up to 120 degrees. Thinner sheets are more manageable, while thicker sheets require more force and precision.
Stamping: This process uses dies to create shapes and features. It can involve cutting, punching, or forming operations, which can be tailored for mass production.
Rolling: Involves passing sheets through rollers to create curves or reduce thickness. This technique is particularly useful for fabricating cylindrical shapes.
Welding: Used to join multiple pieces of sheet metal together, welding techniques vary based on the materials and final application.

Assembly

After forming, the individual components are assembled. This stage may involve:

Mechanical Fastening: Using screws, bolts, and rivets to join parts together.
Welding: As mentioned, welding can also play a role in final assembly.
Adhesives: In certain applications, adhesives may be used for additional strength and sealing.

Proper assembly techniques are vital for ensuring the structural integrity of the final product.

Finishing

The finishing stage enhances the aesthetic and functional properties of the sheet metal. Techniques include:

Coating: Applying paint or other finishes to improve corrosion resistance and appearance.
Polishing: Used primarily for aesthetic finishes on stainless steel or aluminum products.
Deburring: Removing sharp edges and burrs to ensure safety and improve the quality of the product.
