What is Sheet Metal Fabrication?

Sheet metal fabrication refers to the process of creating metal structures by cutting, bending, and assembling flat metal sheets. It’s a versatile method used for producing parts and products that range from simple brackets to complex, high-precision components. The metal used in sheet metal fabrication can be of various types, including stainless steel, aluminum, copper, and mild steel, depending on the desired properties such as strength, corrosion resistance, or heat conductivity.

The sheet metal fabrication process typically involves the following stages:

1. Cutting: Metal sheets are cut into the desired shape using lasers, shears, or water jets.

2. Bending: The metal sheets are bent or folded into shape using press brakes or other bending machines.

3. Assembling: After the parts are cut and bent, they are joined together using welding, riveting, or fasteners.

The process can also include other operations like punching, stamping, and finishing, depending on the specific requirements of the project.

Common Sheet Metal Fabrication Techniques Used in Bangalore

There are several sheet metal fabrication techniques that are commonly used by companies in Bangalore, depending on the requirements of the project. Let’s take a closer look at the most popular ones:

1. Laser Cutting

Laser cutting is one of the most advanced and widely used techniques in sheet metal fabrication. It involves using a high-powered laser beam to cut through metal sheets with extreme precision. Laser cutting offers several advantages, such as clean cuts, high accuracy, and the ability to cut complex shapes. It is used in applications where tight tolerances and smooth edges are required, such as in the automotive and aerospace industries.

2. CNC Punching

CNC punching is a highly automated technique that uses a computer-controlled machine to punch holes, shapes, and patterns into metal sheets. It is highly efficient and suitable for high-volume production runs. CNC punching is commonly used to produce perforated sheets, panels, and parts that require precise hole placements.

3. Bending

Bending is a process that involves deforming the sheet metal into an angle or shape using a press brake or other bending equipment. The metal is placed in a die, and pressure is applied to form it into the desired shape. Bending is widely used in the production of metal enclosures, brackets, frames, and other structural components.

4. Welding

Welding is a process used to join two or more metal parts together by applying heat and pressure. Common welding techniques used in sheet metal fabrication include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and spot welding. Welding is a critical step in assembling metal parts, especially in industries like automotive, construction, and heavy machinery manufacturing.

5. Stamping

Stamping is a mass-production process that involves pressing a metal sheet into a mold or die to create specific shapes. This process is ideal for creating high-volume components with consistent quality, such as metal panels, car parts, and appliance casings.

6. Waterjet Cutting

Waterjet cutting uses a high-pressure stream of water mixed with an abrasive material to cut through metal sheets. It is highly accurate and can cut through a wide variety of materials, including metals, ceramics, and composites. Waterjet cutting is used when heat-sensitive materials need to be cut without affecting their properties.
