What is Sheet Metal Fabrication?

Sheet metal fabrication refers to a process of processing metal sheets, mainly including methods such as shearing, punching, bending and forming. The process includes various cold stamping die structures and process parameters, as well as new stamping technologies and processes. The main processes of sheet metal fabrication include cutting, bending edges, bending forming, etc. ‌12
The application of sheet metal processing is very extensive, and common application areas include automobile body, chimney, iron furnace, etc. These products are typically made of thin metal sheets that undergo plastic deformation through manual or die stamping to form the desired shape and size, and may be formed into more complex parts through welding or minimal mechanical processing.
The specific operations of sheet metal fabrication include terms such as flattening, drilling, chamfering, etc., which play an important role in the processing of metal sheets.

Definition and Basic Concepts of Sheet Metal Fabrication 
Sheet metal fabrication is a comprehensive cold working process for metal sheets (usually with a thickness of less than 6mm), including cutting, punching/cutting/composite, folding, welding, riveting, splicing, and forming processes. Its prominent feature is that the thickness of the parts is consistent. Sheet metal parts are usually processed through stamping, bending, stretching, and other methods, and the thickness remains unchanged during the processing.

Application fields of sheet metal fabrication 
Sheet metal fabrication is widely used in various fields, such as electronics, communications, automotive industry, medical equipment, and construction industry. Common sheet metal products include TV cases, computer cases, mobile phone cases, metal cabinets, etc.
 

Equipment and process flow for sheet metal fabrication 
The main equipment for sheet metal fabrication includes shearing machines, CNC punching machines, laser cutting machines, bending machines, etc. The process usually includes the following steps:
 

Design: Design workpiece drawings according to requirements.
Cutting: Use a laser cutting machine or CNC punching machine for preliminary cutting.
Stamping: Stamping materials into shape using a punch press.
Bending: Use a bending machine to bend the material into the desired shape.
Welding: Connecting various components together through welding.
Surface treatment: Polishing, spraying, baking paint and other treatments are carried out to beautify the appearance and prevent rusting.
Advantages and disadvantages of sheet metal fabrication
Advantages:

Lightweight: Sheet metal parts are lightweight, making them easy to transport and install.
High compressive strength: possessing excellent mechanical properties.
