What is sheet metal processing?

Sheet metal processing refers to the process of cutting, bending, stamping, stretching, welding, and other processing processes on metal sheets to produce the desired shape, size, and structure.

The working principle of sheet metal manufacturing process

The sheet metal manufacturing process relies on appropriate molds and processes to perform precise cutting, bending, stamping, and other operations on metal sheets. The goal of these processes is to convert the original metal sheet into components or products that meet the design requirements in terms of shape, size, and structure through appropriate processing methods and tools.

Steps for sheet metal processing

stores reserve

Select appropriate metal plates, perform material pre-treatment according to product requirements and design drawings, such as cutting into the required size plates.

Design and mold manufacturing

According to the design requirements of the product, draw engineering drawings, and make corresponding molds or fixtures. The mold is used for cutting, bending, stamping and other processing processes to ensure that the metal sheet can achieve the required shape and size.

cutting

Use cutting machinery, laser cutting and other processes to cut metal sheets into the required shapes and sizes according to design requirements.

Bending and Forming

Bend metal sheets into the desired curves, angles, or shapes through mechanical bending, rolling, bending, and other processes. This is usually achieved by placing the sheet metal on the bending mold and applying appropriate force.

Stamping and stretching

Use stamping molds for processing such as punching, stretching, convexity, and concavity to create the required holes, concave and convex shapes, or textures. This is usually achieved by placing the sheet metal on the stamping die and applying pressure or impact.

Welding and assembly

Connect and assemble metal plates through welding processes to form complete components or products. Various methods can be used for welding, such as argon arc welding, laser welding, etc.

surface treatment
Surface treatment of metal sheets, such as spraying, electroplating, polishing, etc., to improve appearance, corrosion resistance, and decorative properties.
Inspection and Quality Control

Inspect and control the quality of manufactured sheet metal components to ensure they meet design requirements and quality standards.

Types of sheet metal

Sheet metal bending

Bend the metal sheet according to the design requirements to form an angle or curve. This type of sheet metal is widely used in the manufacturing of products such as chassis, cabinets, and covers.

Sheet metal stamping

Use stamping molds to process metal sheets through punching, stretching, convexity, and concavity processes, forming the required holes, concave and convex shapes, or textures. Stamped sheet metal is often used for manufacturing electronic equipment casings, automotive parts, etc.

Sheet metal welding

By welding processes, multiple metal plates are connected together to form a complete component or product. Sheet metal welding is widely used in fields such as automotive manufacturing and aerospace.

Sheet metal stretching

Extend the metal sheet through a stretching process to achieve the desired length or shape. This type of sheet metal is used for manufacturing products such as pipes and conduits.

Sheet metal rolling and bending

Roll metal sheets through rollers or rollers to bend them into the desired shape. This type of sheet metal is often used for manufacturing cylinders, curved components, etc.

Sheet metal punching

Create holes on metal sheets through punching technology to meet different connection or fixation requirements. Sheet metal punching is commonly used in the manufacturing of electrical boxes, ventilation holes, etc.

Precision cutting of sheet metal

Use high-precision cutting techniques such as laser cutting and water jet cutting to accurately cut metal sheets to meet high-precision dimensional requirements.
